Q:
Just bought the Tempest prop. The prop has been modified by
Boger. |
| 94 150 Merc |
Was on a 481V (150 XR6) Ranger. Would
turn 62-62 on the Ranger. What |
| |
should this prop do on my Cat? Prop
has excellent bow and stern lift. |
| 23"
Tempest Plus |
What height should I start the plate
at? Adjust up or down? Adjust till what falls |
| 6"
jackplate |
off; h2o pressure, rpms jump, mph
falls, or combination of all three? |
| 2.25"
off transom |
A:
You should have much better performance than the 481V had...I can tell
you |
| |
that! I'd start 3" under
pad and work up.....till the tail gets big and the h2o starts |
|
|
to drop in the turns. Keep the
rpms in the 55-5800 range. |

Q:
Boat has good holeshot and top end, minimal chine. The problem I
seem to |
| 00 225 Merc
EFI |
have is a lack of bow lift. Not really
looking for speed increase, what I have now |
| |
is plenty fast, but I don't want to
lose any to get the bow up a little more. |
| 25"
Trophy |
I don't know a lot about boat setup or
the results of certain changes. Thought of |
| 6"
jackplate |
lowering the motor 1/2" to an
inch and see what that does or moving up to a |
| 3.25"
off transom |
26 Trophy. I seem to have the rpms to
run a little more prop but I'm not sure how |
| 80+
mph @ 5900 |
that will help my problem.
Thanks for your help..... |
| 15#

A:
You have all the components....my guess is that a bit more setback
would help |
| |
both lift and speed....swapping to a
26" Trophy really shouldn't affect lift......it will |
| |
give another 1-1.5 mph tho....I'd try
to keep the big EFI as close to 6K as |
| |
possible tho. |
| |
When running down the lake do you run
out of trim? Is so, add trim extenders. |
| |
They can be had from Land and Sea but
I make my own...the Mercs generally |
| |
do not offer enough positive
trim....it's worth 2-3 mph on the Tritons with Merc |
| |
power. |

Q:
When fill livewells, boat struggles to get out of hole but this seems
to be the |
| 99 200 Merc
EFI |
perfect place for top end and comes
out of hole good if no water in livewells. |
| |
I raised 1/4", but no help and
loss of speed to 70 mph and 12/13# psi. |

Is this the wrong prop. BassCat
Mfg said use 25" Trophy but would like to make |
| Jackplate |
what I have work. |
| 3"
below the pad |
A:
Have you tried removing PVS plugs to adjust holeshot? That's
about all you |
| 72/73
mph @ 6000 |
can do.....I won't run a 200 2.5 liter
under 15# psi. I'd borrow somebody's |
| 13/14#
psi |
25" Trophy to try.....but you're
running very well where you are. I never rig my |
| |
personal stuff based on holeshot or
midrange.....always for top end. |
| |
I'd rather be a dog when heavy and
have top end over a good holeshot and a loss |
| |
of 3 mph. |

Q:
I'm considering going to a larger setback jackplate and need to know
what |
| 92 200 Merc
2.5L |
would be the most efficient setback
for my boat. I'm thinking 10" but I really don't |
| |
know. At 5800 rpm - 69/70 mph my
water pressure runs about 12 psi. |
| 25"
Powertech 4 Bl. |
If I bump the trim down it jumps to 15
psi but I lose 2-3 mph and lose what feels |
| 5
1/2" off transom |
like a lot of bow lift. I've
also got a torque steer problem. My motor doesn't have |
| 69
mph @ 5800 |
a torque tab. This morning I was
running at WOT and decided to trim down some. |
| 12-13#
psi |
At first all I noticed was more water
pressure, so I trimmed down a little more and |
| |
noticed the torque steer lessened so I
trimmed down a little more. The more I |
| |
trimmed down the easier it became to
steer. I don't know what to do about this. |
| |
I originally set the jackplate to my
max mph and didn't know any better about |
| |
anything else. What can I do to
help my setup without losing mph? I posted on |
| |
Angler World about the torque steer
and they said I should get a torque tab so I'll |
| |
be getting one of those Tuesday.
Thanks....... |
| |
A:
Well, there are a couple of lines of thought here. First
off....I never rig for |
| |
holeshot, midrange or comfort....I
keep all my stuff set for max topend. There are |
| |
those I rig for who could care less
about topend but want a very efficient and |
| |
comfortable fishing platform. |
| |
My suggestion is this.....before
changing setup install the torque tab....I think you'll |
| |
like the results. Next....I
think a 10" plate will work on the Cat...but I'd rather see |
| |
you try 2" spacers for a lot less
money than a new plate.....if they don't help enough |
| |
(they'll help tho), then you can go to
an 8" plate and the spacers and have some |
| |
flexibility about your backspacing. |
| |
The more setback will put the engine
in cleaner water which will allow you to keep |
| |
the trim up and still have adequate
h20 psi....plus speed, plus lift. |
| |
Tab it......then space it.....THEN if
needed plate it. |
