| Well I got a lifting ring for my OPTI, I have been playing with engine hieght, I have been raising it one hole at a time.
Well so far I have it as high as it would go now, I have good water pressure, no blow out in corners etc...
I am running a REV 4 21p.
I have gained some rpm and speed, did not get alot of time on it like this yet, I ran it in the 4th hole friday all day on the river with good results.
I talked to out local high perf merc shop and researched the net and from what I could come up with 12 psi at wot is ok.
BTW I peeked over the transom at WOT and the cav plate plate and it is only 1/2" -1" above the water in the highest position | |
