Q:
I just had the jackplate installed on this boat. I only gained 2
mph. I also a |
83
200 Evinrude |
year ago had the powerhead
rebuilt. I believe this boat should be a lot faster. |
|
I am thinking about 63-64
mph. What do you think? Should I go with a 25" |
23"
Rapture |
Rapture? Would you
recommend a different brand of prop. I do not have a psi |
8"
jackplate |
gauge also, so I have no
idea what my water pressure is. Thanks for your help. |
4"
below pad |
A:
The Champ should be 65 easily with the 200.....but the
Rapture is never |
57
mph @ 6000 |
going to get you there.
Swap to a 24 Raker for best results...and you may need |
|
to come up a tad on the
plate. As long as you keep swapping impellers annually |
|
and have no overheat horns
you should be ok at 3.5" under........ |

Q:
I recently acquired this boat to introduce my family to
water sports and |
16" Fish |
re-acquaint myself to
sport fishing. This is my first boat and I am somewhat |
83
115 Johnson |
ignorant on proper setups
(a rookie), hopeful that you can dig into your archives |
|
and make suggestions. To
the best of my knowledge all components are stock |
17"
3 blade Alum. |
from the respected
factories or dealer. My holeshot when loaded for fishing or |
56
mph @ 6000 |
attempting to pull a skier
SUCKS (takes forever), in comparison to other boats. |
|
I also have a tough time
on plane at slow speeds 20-25 mph. I'm considering all |
|
or part of these options -
1. SE Sport hydrofoil for lift, 2. drilling the prop for |
|
water aeration, 3. upgrade
prop blade and pitch, 4. check out prop height over |
|
pad. Would like to
enhance performance at both low and top end but low end |
|
is priority. What do
you recommend for proper setup and what is my redline |
|
number? Thanks for
your help! |
|
A:
The prop you have now may not be aluminum....your engine came factory |
|
with an SST...stainless,
Teflon coated....either way there are much better props to |
|
be had. 5500 is
about all I will spin a V-4 'Rude....it's a good engine but the 90 |
|
degree takes some time to
ramp up. |
|
Anyhow.....try a 19"
Viper by OMC and see if it doesn't help across the board.... |
|
this prop is made for
getting a load moving and will still outrun the prop you |
|
currently have plus won't
fall off plane.....I don't really like whale tails..... |
|
but in your case with a
load and skiing it will probably do wonders...after you |
|
swap props. |

Q:
Previously had a 6" jackplate-due to a problem (underwater
debris) I had to |
191 DCX Elite |
replace the plate, went to
a 8" plate, top speed dropped from 68.0 to 63.5. |
97
200 Merc EFI |
I have extensively
experimented with different plate settings to no avail. I am |
|
unsure how to measure to
propshaft height as this is my first hi-perf boat. |
25"
Trophy |
A:
You have way too much slippage.....25 Trophy at 5800 should be around |
8"
jackplate |
70 mph.....assuming your
prop wasn't damaged and repaired in the jackplate deal |
63.5
mph @ 57-5800 |
you probably need to lower
the engine drastically, like 1" for starters.....if the prop |
15+
psi |
was repaired then try
another non-repaired prop of the same caliber........ |
|
As for the measurement of
propshaft to pad.....lower the engine to parallel with the |
|
ground......use a straight
edge from the bottom of the pad to the lower unit...the |
|
difference between the
straight edge and the shaft is how much the shaft is over or |
|
under the pad....on the
Champ 3.5" under is a good starting point. |

Q:
I live and fish on a 7000 elevation lake. I originally had a
22" Laser II prop |
97
115 Merc |
at wot it turned 4500 at
46 mph. Holeshot was lousy with more than one person |
|
in the boat. I tried
a Rapture 19", wot 4600 at 40 mph, holeshot so so. |
15" Rapture
|
With a 15" Rapture,
wot 4600 at 34 mph. Great holeshot with loaded boat. |
1" off transom
|
Any ideas on how to get a
little more top end and keep the good holeshot. |
34 mph @ 4600
|
I had a mechanic hook up a
remote tach to test the accuracy of my tach and it |
9# psi
|
checked out ok.
Thank you........ |
|
A:
I'd be looking for a Tempest or Trophy over the prop you have now.... |
|
5250 is your redline....so
I think something in a 19 pitch modern bass boat prop |
|
should help
greatly.....the Champ hull rides with a lot of wetted surface...so you |
|
need to free the hull up
with transom lift. |

Q:
My boat is same as Fish Hunter (walleye/dual console) but without
carpet. |
Coastal Champ |
Just got the boat.
Had on the water twice. The water pressure gauge does not |
99
200 Merc EFI |
read steady. Bounces
from 2.5 to 8.5 (I believe not near enough pressure). |
|
I want to change the
impeller in water pump. I believe the engine may be mounted |
23 Trophy
|
too high also.
Running too many rpms. I want to try a 25" prop and drop engine |
Even with pad
|
down a little. Boat
handles great and no chinewalking at all. Speed increase not |
60 mph @ 6100
|
really the concern,
although would like to go a little over 60; water pressure is |
|
main concern. What
should I be reading and do you think engine too high with |
|
gauge "bouncing"
from 2.5 to 8.5? |
|
A:
I think you're too high with the engine...that's why the varying psi
readings..... |
|
I think a new impeller is
due also....but lower the engine substantially and see if the |
|
23 won't turn an efficient
5800 rpms....I don't necessarily think the 25 is |
|
warranted.....10 psi is
about the min I will run a 2.5 liter Merc. |
Second question ...... |
Q:
I lowered the engine as you suggested. The propshaft is now 2"
below the pad |
|
instead of even with it.
Water pressure is now up to 18-20 psi at WOT instead of |
|
bouncing from 2.5 - 8.5. I
changed the impeller in water pump. The old one was |
|
fine. Engine was
just too high. Before I e-mailed you I bought a 25" Rapture. |
|
I tried this with the
propshaft 1" below pad. Only got 5600 rpms and 56 mph. |
|
Lowered the engine another
inch and tried my 23" Trophy and got 6000 rpms and |
|
62.5 mph. What do you
think so far? Should I try a 3 blade in a 24" pitch? |
|
Engine height seems OK?
Thanks for the help! |
|
A: I'd say you're on the right path.....18 psi means you
could actually raise the |
|
engine some more....15 psi
is about the min. I like to see them run....but they will |
|
live at 10. |
|
I'd try a 25 Trophy
next...if the 23 is doing 6K look for 5700 with the 25 and |
|
almost 65 mph...if the
holeshot is ok and you like the handling characteristics I'd |
|
say you'd be done.....on
the other hand....keep trying props! It only costs time |
|
and you will get a feel
for what's best. |

Q:
Just bought the boat and was wondering what prop you would suggest for
best |
02

overall performance.
I fish local tournaments with a full load in the boat. |
Optimax |
The dealer will allow me
to swap props until I find the one I want. Thanks.... |
|
A:
In my brief Champ experience I've come to believe the Champs like the |
23" Trophy
|
3 blade.....I'd try a
23" Tempest....the 23" Trophy probably ain't bad tho..... |

Q:
Todd, I'm having a 2002 200 Yamaha EFI VMax installed and looking for |
02
200 Yamaha |
advice on a prop.
Before this motor, I had a 200 Ficht, ran a 24" Raker and |
|
turned 5800-6000 by
myself. It would get a little squirrelly at WOT but it was |
6" jackplate
|
driveable. I'm
looking for good all around performance, good holeshot and top |
|
end. Don't know much
about the Yamaha props, appreciate your suggestions. |
|
A:
I'd say the 25" Yamaha ProSeries is the ticket....steer clear of
the XL.... |
|
too much diameter and loss
of rpms. The 200 Yam should be a tad stouter than |
|
the 200 Ficht.....look for
5800 for a good all around operating rpm. |
98
Champion 202 DC |
Q:
I am trying to improve the speed on my boat. The speed is with a full |
98
200 Merc |
tournament load and two
people. It does not lift very good either. If you have any |
|
suggestions please tell
me! |
25"
Tempest |
A:
You're basically doing what a 202 with a 200 should do....with the
exception |
6"
jackplate |
of adding 2" more of
setback with spacers....and you might come up a tad on the |
2
1/2" off transom |
plate.....the setback
should help lift and speed....your might borrow a new 24" |
64
mph @ 5600 |
Tempest to try to get you
on up towards 5800 and full operating range....that may |
13#
psi |
not be as fast as the 25
at 5600 tho..... |

Q:
I've tried a 24 Raker that speedoed 62 @ 5200 rpm. The Renegade
doesn't |
187 Elite |
ever feel like it gets the
boat up on pad, with the Raker at 5000 rpm it feels like it |
01
150 Johnson |
leaps up and you have to
drive it just a little. I think the Raker gives better |
|
performance, only downside
- it seems to slip occasionally in turns and big waves. |
23"
Renegade |
But wonder if maybe a
25" Renegade or similar will give better performance than |
8"
jackplate |
the 23" without
gaining so many rpms. Factory recommends 5500 top. |
3.25"?
below pad |
Any suggestions would be
greatly appreciated, maybe something simpler I am |
6"?
above transom |
missing because I am setup
ignorant. Thank you........ |
60
mph @ 5800 |
A:
My first guess is that you are jacked too high for the 23" 4
blade....excessive |
20#
psi |
slip. The 150 OMC
will spin 5800 all day long....I wouldn't limit it to 5500. |
|
The 24" Raker will
run higher than the Renegade....I think you should lower the |
|
engine about a half inch
and try the 23" again.....however....I think a Merc 23" |
|
Tempest will be the 'cat's
meow'......it will take a Merc flo torque hub for the OMC |
|
to find out tho. |

Champion 206 |
Q:
I don't feel I'm turning enough rpms. The above speed is very
little gas, |
02
225 Yamaha |
livewells empty, all my
tackle and when it's WOT it starts to walk. I had it up to |
|
71 gps but I trimmed back
down to control it. My problem is when I fill up with |
27"
Yamaha |
40 gal of fuel, extra
person, livewells full, I have complete control but I'm only |
10"
jackplate |
getting about 5200-5300
rpms and I don't get the lift that I should. |
69
mph @ 5400 |
What could I do? The
jackplate is raised about 1.5" above the flush position. |
19#
psi |
I hear about double cup
props and re-cups; will any of this help? |
|
A:
Cupping the prop will kill the rpms even worse.....it would
help lift, but |
|
Champs aren't big lifters
anyway.....they aren't made to be. |
|
I think you simply need to
drop to a 25" Yamaha PS prop....stay away from the |
|
XL Yamaha. If you're
at 5400 now.....the 25 should put you closer to 6K....that's |
|
where the big Yam makes
power....at 5200 you might as well have a 175 on the |
|
back. Play with
plate heights also.....take her up some. |

Champion 184 |
Q:
Had my carbs rebuilt and oil injector disconnected and was told that I
should |
87
150 Merc |
try a different prop. I
have a 23" on now and mechanic told me it is too much for |
Black Max |
that motor to turn.
I don't have a great holeshot. He said I should use a 20" |
|
Tempest or Trophy. I
measured the propshaft by lowering the motor till vertical |
23"
prop |
and running tape along
bottom of boat and measuring to center of propshaft, if that |
1"
bracket |
is the correct way to
measure it! Any advice would be appreciated. |
3.5"
below the pad |
I am eventually going to
get a 10" jackplate. |
55
mph @ 5000 |
A:
A 23" Tempest should work well with your rig.....if you
had a jackplate..... |
|
The easiest test in the
world is to try another prop....and you need to get the 150 |
|
up to 5500 or so......so
I'd say a 21" Trophy or Trophy would be the props to try. |
|
Also I think I'd look at a
6" plate over the 10".....the Champs are tail heavy |
|
already and that much
setback will bury the engine deep in the water while idling. |

Q:
I traded in the dog of a 4 stroke I had when I asked questions before.
The |
00
135 Merc Opti |
boat ran horrible. Was a
115 - 4 stroke Merc. Now I have a 135 Merc |
|
Optimax, what a
difference!! What do you think I should be running. It only has |
25"
Tempest |
had 8 hours on it, will it
come alive more after 10 hours of break in and double |
6"
CMC |
oiling? And no
matter how high or low I set motor I only get about 12# psi max, |
4
3/4" off transom |
maybe 13. I'm
running with 2 holes with 7/16 plugs and 1 fully open. |
2
3/4" below pad |
Killer holeshot, motor
feels very strong on this small boat, but was looking for |
60.5
mph @ 5400 |
65 on top end, dealer told
me I could see these numbers. |
10#
psi |
181's with a 150 run 65,
so how about a 171 with a 135 running 65? |
|
Or am I dreaming! I
couldn't run it lower, about 3 1/4" below pad because of |
|
bad chinewalk. Any
help would be great! Thanks Todd!! |
|
A:
Yeah.....I think 115 4 strokes are for pontoon boats.....maybe
the 225 |
|
4 strokes will impress
me.....but so far no 4 stroke does. |
|
I think you're close to
all you're going to see....I disagree with 150 hp 65 mph |
|
181's.....62, yes......not
65 and not in summer. I think you need to give a 23" |
|
Tempest a try and see if
gaining some rpms helps your HP output...5400 is a tad |
|
under what I'd run it. |
|
If you learn to control
the chinewalk and can jack it anywhere it wants to go you |
|
may pick up a couple more
mph.....also try a 24" Trophy to see if more transom |
|
lift will free you up a
tad.....I think you're in the prop experiment stages and small |
|
jack plate changes. |

Q:
Boat is loaded for tournys. Suggested prop for highest top end? |
93
200 Merc EFI |
|
|
A:
The 202's I've done like the 3 blade....your biggest problem is lack
of rpms.... |
25" Tempest
|
you have an engine that
redlines at 6K and isn't making full power at 5300....I think |
62.8 mph @ 5300
|
the Tempest is the prop to
run.....I just think you need to drop to a 23". |
15# psi
|
Yamaha props do well
also....the ProSeries. The 23" should get you to 5700 rpm.... |
|
up to where you're at 200
hp instead of 175 hp at 5300. |

Champion 202Elite |
Q:
How high is reasonable to lift the motor? I installed
the jackplate but the |
225 Merc EFI |
water pressure was this
low before, so I asked some questions and was told that |
|
the 3L block didn't have
high pressure. Now lately the overheat buzzer comes on |
25"
Tempest |
after a 10 min run at 5000
rpm and the w/p is getting even lower, 6-8 at 5000. |
6"
jackplate |
I am going to get it
looked at today, but am I eating up the impeller or what's up |
2"
off transom |
with my engine height?
Is 2" too high? |
69.9
mph @ 5800 |
A:
12# psi in the turns is the lowest I will go with a 3 liter.
10 is too low. |
10#
psi |
You may need to go down a
bit. |
|
I think you need to
install a new impeller now and see what happens.....the numbers |
|
look pretty good on the
setup tho....about what I'd expect to see on a 202/225. |

Q:
I am turning about 300 rpms too much at WOT with the 25" Yamaha. |
01
225 Yamaha |
This is with 2 people (450
lbs) and all of our gear. Holeshot is real good. I was |
|
wondering if you think I
could twist a 26" Trophy? At these speeds I do not have |
25"
Yamaha PS |
any chine unless I over
trim. |
8"
jackplate |
A:
The 26" Trophy would be a good choice....but I'd like to
hear what a 27 |
69
mph @ 5900 |
Yam does.....in theory it
should cost you about 400 r's.....but maybe not. I turn the |
21#
psi |
Yams I do up to 6K and try
to set them to run at 5800.....so I don't think you're in |
|
any danger....the 25 Yam
is a hard prop to beat and 69 is about where I'd say you |
|
should run. |
|
If it was me I'd jack it
to 18# psi and run it cloer to 5800.....the 26 Trophy should |
|
knock you down to 5400. |

Q:
Boat seems to perform well at WOT, but the holeshot SUCKS!!! Thinking
of |
196 Elite |
trying PowerTech TR04
24" pitch. The boat seems a little large for the 200, but |
01
200 Merc |
that's the rating.
Have seen this model perform better. Any suggestions would be |
|
a help. |
25"
Tempest |
A:
From what I know of Champs and Mercs you're doing exactly what you
should |
6"
jackplate |
be doing. My only
realy suggestions would be to pull the PVS plugs till you find |
69
mph @ 5800 |
a combo that lets you spin
up some r's at holeshot....and to try a 25" Trophy to |
15#
psi |
gain some more transom
lift the free the boat up. |
|
Prop swaps are going to be
the easiest way to find performance....I'd try the |
|
Yamaha 25" ProSeries
to see if it helps the holeshot also. |

Q:
Prop have cavitation burn on it. I was wanting to know what is
causing it. |
97
150 Mariner |
Someone had told me that
the motor is too high and the prop is coming out of the |
|
water. But I think
the motor could be raised just a bit more. Just got the boat. |
24"
Trophy |
A:
Cavitation burn on one ear or all 4? A disrupted water flow over
the lower unit |
6"
jackplate |
will cause a burn.....but
it usually shows in the case also....2.4 and 2.5 Merc lowers |
5"
off transom |
have a bad spot just
behind the intakes that will burn fairly easily. |
62-65
@ 5300 |
I think you can come up
some more....I honestly don't think you have enough |
20# psi
|
motor or rpms to cause a
high setting burn. |

Champion 202 |
Q:
I know that my boat should run faster because I talk to people that
have this |
98
200 Merc |
boat. What can I do
to speed my boat up? |
|
|
26"
Tempest |
A: I don't have tons of setup experience with the
Champs...but....the 26" is way |
6"
jackplate |
too much prop for the 200.
The 202's I've done in the past have liked the 3 blade |
2"
off transom |
over the 4...so I'd
recommend the 25" Tempest. |
63.9
mph @ 5400 |
The 25" should get
you to 57-5800....an rpm more in the powerband of your engine. |
16#
psi |
This will add speed as
well. I've been in a 202 with 2 men and a 200 OMC at |
|
68 mph with me holding the
gps...so I think you have some to gain. |
