Spin out issue

I have a 2006 225hp Yamaha HPDI on 1998 20 ft Skeeter. Went fishing today but it was short trip. When I hit the throttle to get on plane all I got was a spin out. Loud and no bite from prop. Goes into gear easily and can move the boat at up to fast idle. But the spinning out of prop begins when I hammer down.

Not sure if the hub blew out or what. Took prop off and did not see anything wrong. But the nut on the prop was not as tight as it should have been but the cotter key was in place and only very minor "wiggle" of prop. It was put on motor a few days ago. Would the fact it could have been tighter affect the performance.

Not a mechanic and would appreciate getting some help.

Sure sounds like the hub has spun out to me. Nut would have to be really loose to allow the shaft to spin inside the prop.

Sounds like the hub has spun loose from the prop body.

You need a new prop hub....the rubber has broke down in yours and its spun the hub.

A propeller shop can press one in for you.

Like everyone else sounds like spun hub. There easy to install sometimes the problem is getting old outer. Rubber out.

How do I check the hub? Took prop off and didn't see any damage but will take it off again today. Is a Yamaha prop, 4 blade 26 pitch. Is th hub internal?

The hub is pressed in. May take a prop shop to determine if it's slipping or someone with much more know how than I can offer.

Like everyone has said. You have a spun hub. If you want to verify that, draw a line on the back of the prop (see red line in picture) then try it again. If the line is no longer straight, the hub is spun. Take it to a prop shop to have a new one pressed in.

I appreciate all the input. I am dropping prop off at shop tomorrow. Although I don't post often I do lurk here quite a bit. Will be giving the bass fishing up for the year soon, then onto the crappie.

Maybe I can contribute a bit more if the crappie on Douglas Lake cooperative.

Thanks for the input. Dropping it off at prop shop in morning. Don't post much but I do hang out here a lot. It's a good site and the wealth of knowledge is appreciated.

https://www.crappie.com/crappie/arka...ropeller-help/ I had this problem as well. Sent my prop to Port City in Ft Smith. Here is the link to that thread. Hope this helps.

Could also be that there is something hanging on the bottom of the hull that is causing the prop to ventilate, or there is an issue with the trim on the motor, although I suspect you would notice if it was not trimming down all the way.

Had that problem a few months ago, was running into a heavy chop and had the motor trimmed way up, when I turned to go with the waves, the prop immediately blew out at anything more than idle speed. Took me a few minutes to figure it out, but as soon as I trimmed down it went back to normal.

We send props to general propeller in FL., nibrel and ss . they weld and polish and balanced, looks like new. Aluminum props. we just replace, but they can repair them like new. The nibrel props. we send are replacement cost $800.00-$1400.00, they refurbish them for $125.00-$250.00 , outstanding customer service. We save customers $100.00's of $. Now you do have shipping cost.

It's nibral misspelled.

Got the prop back from shop. Worked great with new hub pressed in. Runs as good or better than ever. Thanks to all who offered some input, it was appreciated.

Good deal
