496 Sea Pump rebuild

That's my first choice also but for $97 this looks like a viable option...I move allot of sand and I'm surprised mine lasted for 450 hours...been contemplating a sea strainer but I'm worried about the occasionally grounding...which happens no matter how many times I've gone down the same river...the sand just moves faster then I can usually remember... Lol
I put a pair of these in my boat this year. I've put about 10 hrs. on it so far with no issues.
My only concern is with their shorter impellor. I asked them who manufactures the shorter impellor and they told me they did (which I find hard to believe). First concern is the quality of the impellor compared to Merc and how long it will last. I then asked them what do I do if they are out of business 2 yrs from now when I want to buy 2 more impellors. Their answer was we wont go out of business. hmmm.
One other thing I didn't feel comfortable with is that when bolted back together with the plate in between the 2 housings, the pulley would be moved out .060, and I had concern about the belt alignment and belt wear. So I ended up pressing the pulley further down on the shaft .060 so it would be back in alignment. There is no machined "stop" on the pulley shaft, so it can be pressed in further. I used a hyd press and dial indicator for this.
If I find the impellors are not lasting as long as Merc, I will just break down and buy the Hardins when the time comes.

So I know I have to do something, but wow - these guys make me nervous looking at them. Hopefully they last and I agree with you, I would have adjusted for the belt alignment as well.
Keep us informed !
Best of luck.
You do have to grind away the thickness of the plate from the bracket that mounts to the pump...however, if you ever elect to replace with Hardin or OEM all you need to do is add a washer to make up for the material removed...simple setup...when I first installed the impeller it was sucking so hard it almost collapsed my garden hose...but after a few hours use its definitely not sucking like new 10 hours ago! I still get a five degree temp rise coming off plane...when this goes I'll try the Hardin one next! But all and all its a quick fix and will deff last one ore two seasons...worth the money? Yes!
