  • Original Prop Won't Go Back On

    My old aluminum prop won't slide back on all the way after being off for 4 years. It is not corroded or damaged as I can see. F40LA 2014. Yamaha. Any ideas? Splines look OK. It will only slide on about half way.

    Did you grease the splines? I’d clean things up with a wire brush then try with some grease.

          I did try a little banging with a small sledge hammer with a 2x4 in between and it did not make a bit of difference. And yes, I have some grease on it. There are some pics on the engine forum where I first posted this. Thanks
