Wondering what anybody's ideas might be on this. Running a 26 ft Wellcraft Nova with a Bravo I, mildly blown 454, and a 23 pitch 3-blade. When I hammer it out of the hole, it goes for a short period and then feels like I have a cavitation issue. If I baby it up until it's on plane, no problems. My trim must have slight leak as the outdrive requires fairly regular adjustments and the trim will "sag" if it sits on the trailer for a few days.
My question, is this a cavitation issue with the prop or is my trim pump not strong enough to keep the outdrive down in the water? I think it's the latter because when this "blow-out" occurs, I've noticed a little rooster tail from the prop angling upward.
Has anyone experienced something like this? Would a new trim pump fix it? Thanks in advance.
