Re: 140 suzuki on 20 MA
Loon what your RPMs top out at ? 13x17 is too small. I think its atleast a 14" prop. When I first ran my boat with a 14x16 I had way too many RPMs. I then went to a 14x18 that came with the motor still over on RPMs. now with a 14x20 I and still running at 6200 so I want to try a 14x22 when I find one ebay. I might be able to get another 1 or 2 mph out of her!
I dont like aluminum props as the tend to flex out at high RPMs
