There was great debate over whether to lower the engine a peg, since
now it sits a little higher when vertical, but with the additional
setback (about 7") and additional down tilt, we figured the water would
be quiet enough to give me good performance. I can always lower it a
notch if I don't like the way it performs this weekend.
And the answer is... I don't like the way it performs. Oh, it gets on
plain super fast, but now I have a HARD pull to the right. I know I
should be able to tilt the motor back up to about vertical, but now at
cruising speed, vertical brings the prop up too high and I get excessive
revving.
Am I right in thinking that the hard pull is because the motor is
tilted in too far? Will lowering the motor a inch (or two) actually
alleviate the problem by letting me tilt out farther?
Thanks!
Have you tried adjusting the trim tab?
That might help but I suspect he's getting bow steer. He needs to lower
the motor and make sure he has some bow lift and the bow wake starts
about 1/3 of a boat length from the bow. Once he has that he can tweak
for the performance he wants.
So that being said, if I had neutral steering before I added the 7"
setback from the power tilt unit, Do I need to drop the motor down 1" to
make it equal with its height prior to the modification, or do I need to
drop it farther?
