Q:
Todd, not sure on speed and water psi, I just got the gauge
hooked up. |

The boat pulls to the right
when I give it about half to 1/3 open; is this prop torque |
| |
or maybe cause the motor is
too low? What will it do to handling at 3.5" below |
| 24"
Raker |
the pad? How do my rpms
sound for the 20' boat and 200 hp motor? When I |
| 5"
below pad |
raise the motor will rpms
increase? Thanks........ |
| 5300
rpm |
A:
You're way too low at 5" under....if you have cable
steering you'll probably |
| |
always have torque.....I
wouldn't rig based on steering torque. You can always |
|
|
add a skeg mounted torque tab
when the setup in complete. |
| |
The 3 liter will spin
6K....start jacking and watch it come to life. |

Q:
Todd, just bought boat, all I have is 150XP Evinrude. I
have not put motor on |
| 87
150XP Evinrude |
yet so I can't give setup,
that's what I need to know. How far to set the center |
| |
of the prop down from the
bottom of the boat? My jackplate is probably 4". |
|
23" SS prop
|
Boat is a 20dc Astro bassboat.
How fast should it run with this motor? |
| |
What do you think about the
automix oil, keep it or chuck it? |
| |
A:
Set the shaft 3.5" under the pad and run a 22" Raker
prop.....it will do |
| |
55-58 mph gps. Keep the
VRO....actually you have no choice....it is the fuel pump |
| |
as well as the injection pump
for the oil also....you can add some oil to the tank also |
| |
for insurance if you believe
failure could be imminent. |

Q:
The information is with 2 guys, about 30 gallons of gas, one
livewell full and |
| 93
200 Merc EFI |
tackle. What prop would
you suggest? Would you add a jackplate? |
| |
Also, please note that I
cannot lower motor any more on the transom. I would like |
| 24"
Trophy PVS |
to get a little more speed.
What would you suggest? Thanks..... |
| No
jackplate |
A:
Swapping to a 25 Trophy will give more speed now...
with no other changes. |
| 1.5
- 2" off transom |
Probably 2 mph.... Your
numbers indicate a slippage problem....at 5900 with the |
| 62
mph @ 5800/5900 |
24 you should be closer to
70....67 or so. I think you need a plate badly....and an |
| No
psi gauge |
h20 psi gauge......after
plating you may or may not need a prop change.....being able |
| |
to get your prop into the
water more and reducing slip may cause the 24 to work |
| |
exceptionally well...you have
have to step up to a 25 anyway with the reduction in |
| |
drag. |

Q:
Just wondered what you think about a size of jackplate for
this boat. I know |
| 96
175 Merc EFI |
this boat was supposed to come
with a Trophy but don't know what size pitch to |
| |
start once I get jackplate.
Also, have you ever seen anyone put a hydrofoil on this |
|
23" Laser II
|
large motor bassboat.
I was told you could prop for speed and let the hydrofoil |
|
No jackplate
|
make up the difference for the
holeshot? Any comments? Thanks for your time.... |
|
4" off the
transom
|
A:
If I plated it....I'd go 6". And I would plate
it!! Replacing the Laser2 with a |
|
62 mph @ 6100
|
Trophy or Tempest prop will
make you think you have another 50 hp compared to |
|
No psi gauge
|
what you're doing now.
I'd say 23 pitch.....don't try to relate to Laser2 rpms to |
| |
Trophy or Tempest r's.....6100
is too high....5800 is recommended. |
| |
I'm not a fan of
hydrofoils....there is always a way to make the boat leave
better |
| |
without adding the
foil....although the solution without the foil would be better
with |
| |
the foil.....I still don't
like them and won't rig one. Dragboats use hydrofoils
all the |
| |
time.....400+ hp.....so having
one on a 175 is not unusual. |
