I have a 5.0L Mercruiser Alpha 1 w/ Hirel TBI on my 19' Rinker runabout. Currently has a High Five 21P prop and the hole shot is weak, struggling to pull a slalom skier out of the hole.
Turning 4,800 RPM WOT and about 3,000 RPM hole shot while it sits there pulling the skier out of the water...
LOVE my boat: Chaparral 21-footer with 260 HP V8. Problem is she is a bit much for my aging Grand Cherokee to handle, to the tune of a $2000 transmission rebuild last week.
Looking to scale down to something more manageable in the 19-foot range. Finding that alot of the boats in this range...
Have read thru the other threads on this topic, so thanks for the insights. To recap, my engine idles/revs great with no load and runs great once it planes out and reaches some RPM, but bogs down badly during holeshot.
I had a good local boat shop do a tune last summer and they also rebuilt...
