    Xpress SV16

    I have a 2008 Xpress SV16 with a 2008 yamaha 50 two stroke. Its spinning a 10 1/4 x 14 pitch aluminum prop. When I have someone in the boat with me it is a dog coming out of the hole. With the current prop I get up to 5300 rpms about 29-30 mph before porpoising. My question is should I go to a Stainless prop and what pitch should I go to if so. I had posted this an the Xpress forum but my model is not very common so no one really had any insight. I was just seeing if anyone could offer some insight.
    Thanks
    Spencer

    Did you figure this out? Im running a g3 17', 25hp. I called a local prop guy, asked the same question about stainless. He said no, for that size boat, and hp, save your money. Change the pitch instead. It worked.

    I would agree with you Skunked. On my 90 I was right on the fence as to whether a ss prop would help. I talked to the guys at PowerTech and they’re awesome. They picked the prop for me based on the info I’d gathered and if I didn’t like it, $35 to exchange to a different model but that wasn’t necessary. Top speed only picked up 1mph bit the boat turns, rides and stays on plane at such lower speeds now.

    I have not really had a chance to mess with it. I have been busy with school and work. So based on Skunked's info I might try dropping down to a 13 pitch aluminum prop and see if that helps at all. Thanks for the info guys I might also call Powertech like you did Casslaw.
