Yeah no worries buddy.. the whole system is brand new so that’s why I’m gonna do some more trial and error before I go that route.. believe me I thought about just buying a assist pump but I have a feeling I’m dragging to much engine in the water with not trimming the engine.. thanks man!

Default AV Plate at Water Surface





Big Sean, as I previously remarked raising the engine may help. Check that the AV plate is at the top of the water. The first pic with black tape on the top of the AV plate was in Oct 2019 shortly after I redid my transom on my 20' Seafari and raised the engine about 0.750", which made steering easier particularly at higher trim angles. At the previous position when trimmed way up, it was like I could not steer off of straight ahead.

The second pic is from a few days ago, actually to show the trim tab. Both pics were at about 28-30 mph.

After years of being obsessive in motor height adjustments and propping I have come to the conclusion that I start with the motor as high as I can mount it. It is easy to determine if you are too high by just putting the hull into turns. If it is anything over a slight cavitation... It is too high. Starting lower than that never lets you know you have hit the sweet spot if you just settle with the hole in-between that seems to be good.

Since the highest mounting height with good traction is the best performing and most economical... Highest available is the best starting point.

Default Kmoose’s Engine Height

As usual Kmoose’s advice is sound and cuts to the chase- start high then go lower if need be. As Bushwacker remarked the dealers always seem to mount them too low.
It occurred to me after posting my AV plate video that my usage is on lakes, those of you in rougher stuff might need it lower. With my High Five 5b prop, I have no cavitation in tighter turns in testing than I would normally attempt. Once height is correct check your prop RPM at WOT. Dealer started with 21p, I am at 17p now.
