- (2) Merc 5.0’s
Set up is 2004 Sundancer 300. Twin 5.0 MPI's, Bravo III outdrives and 22 degree dual props.
Boat seems to have a cavitation issue. The boat is under powered in my opinion with the 5.0's and certainly with more than 4 adults, full fuel, etc. Has always had a difficult time getting on plane and I have to use the trim tabs to help it finally get over the hill.
However, 9 times out of ten it will either cavitate or something is slipping causing the rpm to go from approx. 3,400 to 4,200 for example. I'll then back off the throttle, furthing the issue of trying to get on plane. It will also have this issue at cruise in seas greater than 2'-3'. Issue happens on both sides but for some reason appears to be more prevalent starboard.
Thoughts or similar experiences?
