Post GDSD 11' 3 blade
Has anyone ever tried the GDSD 3 blade on a 31-35hp GDLT?

If you have the available rpms to turn it, anythings possible.

I took a 11x10 2 blade prop and put it on my 31hp gdlt that calls for a 10x6 blade. RPM's dropped from 3850 to 3350 and only pushed my 18ft boat 16mph.

I dealt with trying to get more speed out of my 31gdlt for 5 years and finally realized the only way to do was to sell it and get a short-tail.

Start saving your money and buy either the frame from MB or buy a used surface drive.

surely someone on here has one that is a bit lite for his sd,maybe it would work for your 1 to 1.
shouldnt have to pay too much for a "used up" wheel.
i done gave my old one away.
