My boat is a 2005 Triton TR 196dc with a 200hp optimax. In the summer at lake Powell (3300ft elevation) and 85-100 degrees I switch to my back up prop to carry a load in the heat better. It's a quick silver laser II 23 pitch.
It spun the hub a year ago and before and after getting it repaired it continues to ventilate when getting up on plane. Is this a fixable issue with more cup? I've lowered the engine a bit from where my 25p prop likes to run and it's done nothing to help. Ideas?
