@@SailHub i love your work - need to get a big Ultra anchor

[@SailHub]

@DirkJacobsz Dirk! Thanks! What a fab comment to wake up too! Yeah, the Ultra is awesome. Shame the price tag is awesome too… We took it off and packaged it up to send it back to Ultra when we sold our boat😔 The new owners loved it so much that they bought it back and it’s now back on the boat again. We’re onto something new now, still boats of course, we’re soon to start building something new, I can say one thing, it’s hard to think of putting anything other on the front than an Ultra!

[@jwdundon]

My pump is pumping like crap, it DOES have some GROOVES (front to back) in the housing, how do i fix those? Sand paper???

[@SailHub]

Well, it may end up being a replacement. The thing here if you try to fix it you may win or end up worse, but really it can’t stay the way it is. If it were me I would get too smoothing out the rough spots with sandpaper as you suggested. You can take away all of the high spots where the impeller rubs and possibly even the smaller low spots, this should help a lot. Regardless of what you do, I think it’s important to see what’s going on with your sea water strainer as it sounds like it’s not been doing it’s job properly.

[@drizler]

How about lightly honing it like an engine cylinder . I’m not saying I’ve done it just floating an idea that I’d consider trying if I had your situation

[@SailHub]

@drizler that sounds great, only it’s not circular. I’m not sure how you would get the honing tool to manage the flat?

[@NinoPrez007]

I installed the impeller housing after summarizing and now I hear a grinding sound and the belts don't spin... I've taken it apart 2 times now and the same result. Any ideas of why?

[@SailHub]

The belts don’t spin… Ok, so it sounds like you have taken the impeller hosing off and it’s drive mechanism? It most likely that the drive gear wasn’t aligned when you re fitted it. Do you have any pictures? If so send them to [e-mail] and I will try yo help. Cheers, Chris

[@NinoPrez007]

@@SailHub I just sent you a picture of my housing. Thanks bro!

[@NinoPrez007]

@@SailHub I didn't have the support bracket in place! I think that's the problem. I will put it back on.

[@SailHub]

@NinoThePrez ok, good luck!

[@NinoPrez007]

@@SailHub I think it is seized.. Nothing spinning...What do you think?
