Last year I was running 3 blades on my SSM IIs and turning out. This year I am trying a set of 4 blades to try to get the boat to plane a little easier. The engines at twin turbo 454's making (est) 600 HP. Last year when I would trim the drives up it felt like the boat kept going faster. What would people consider too much trim knowing that it is a TRS outdrive (input shaft support bearing in the tailstock vs bravo style gimbel bearing).

Where did you find the 4 blades?

I don't think where the tailstock bearing is makes any difference because it is all being transmitted to the transom any way.

Found them on CL last year. Ill have to cut my anticavitation plates to give them room and I'll have to use a thinnner lock nut on the propshaft but otherwise they fit. I'm hoping they will give me the results I'm looking for
