I have an 85 260 da and have great results with a 15 1/4 x 15, 3 blade aluminum. That was what Sea Ray suggested. What kind of drive? I have an alpha I, SEI replacement.
It's called bow steer. It's common in sea rays built in the 80's. Even single screw. You just have to learn how to trim differently to fix the problem. Over trimming/tabbing makes the problem WAY worse. Good luck with ur new drive.
I have a 2 year old SEI replacement for my alpha I. I noticed some knocking this season that sounded almost like a popcorn maker. WELL........... Saturday my temp spiked and I was smoking. Found out that knocking noise was a damaged impeller. Boat is being pulled to replace. Gotta check with SEI...
