Problem with 250 pump
Hey guys. Bad news. Was having my ultra with 220 hours on original bearings upgraded to the 300 pump set up. I have a solas 16/21 prop on it. While pulling the prop and shaft out the prop wouldn't come off. Here the prop itself seems like it twisted the threads and is locked on. Now I need new prop and shaft with all bearings and seals which I was changing anyway. Also the pump housing seems warped so I pretty much need everything down there. Has anyone seen this with the solas props "back threading" for lack of a better term? I do all ocean riding and bay and saltwater so it gets rough and fast. I never heard of a prop doing this. Is solas have to loose of tolerances that this could happen? Not sure what I am doing prop wise now. Any suggestions? Stock , 15/23. Someone on here has a 15/23 for sale. Very bummed out. Was hopeing to ride this weekend

Use heat on the centre area of the prop to release it...... thry can be FRIGGIN tight

Yep ,propane torch 8-10 seconds on all three sides right in the middle where the threads would be underneath...
Hows your vise,sturdy?

Thanks guys. The thing is it needs a new shaft for the pump upgrade anyways and the prop is due for a new one. Any opinions on prop choice?

Let me know if your need that black iron prop holder, I've lent it a Kawa rider friend last yr and made sooo much easier to take off...that nub gets chewed up real good in these vises..
I can mail it to you...

I had 350+ hours on original prop when i upgraded bearings and prop. I actually had to have my pump machined on a lathe as it had swollen up and WOULD NOT allow a new prop to spin in the pump. You may have to do the same. Also I have a new 15/23 for the 250 if you go that route.
