    I have a short shaft tiller on my 13' gheenoe that won't push this boat. I've tried every trim position on the motor. It won't open up. Every time I get up to speed the motor rev's and the prop loses bite. I had a 5hp that worked fine just needed a little more speed. I've been told it could be the hub or it could be the shaft is too short for the hull? Need some insight before I throw more money at it.

    I would doubt it's the hub I would look at motor height, What pitch prop are you running? Sounds like your blowing out when you try to plane off?

    I can't get the motor any lower without a jack plate.  I think it standard 8 pitch.  I believe it's aluminum.  It has 8 stamped on it. And yes it will move, but when wot it blows out.

    make sure the foot of the motor is as close as possible to the transom "tucked" 8 pitch is about right

    Well, I solved my own problem. Thanks for the insight, though. It always helps if you have the correct prop on the motor. Thanks craigslist. Here's a before and after. I decided to go buy another prop, one that was designed for a Nissan, and not a Yamaha. I didn't inspect the motor close enough when I bought it. There was a gap between the prop and the lower unit itself with the old prop. Then there's a pic of the new prop that's designed for it. No gap. I'm running it tomorrow to see how it works out.

    Motor works great now that the prop has been changed. As far as that prop is concerned it does have 12 splines. I only thought it was a Yamaha prop because of the guy I bought it from. He worked at a Yamaha dealer.
