270 sundancer prop choices
In addition to my sonic I have a 1990 270 sundancer with a single 340 hp 7.4 1.50 Bravo 1 drive
WIth the 15 P 3 blade prop that the seller just
threw on there I am getting 5500 rpm wot in fresh water. It seems like I have to maintain 3500 just to keep it on a plane.
What are the best choices for a 5800# 20deg dead rise boat ? I will use it is salt and fresh water.
19P mirage? 4 blade?? Sea rays prop matrix doesn't list the 270 in 1990
Any help will be appreciated very much

See if you can find what they put on later model 270s. Same size boat and they used the 7.4 for a long time...10 years after yours. I thought most of those were 300hp
