Anyone changed impellors -496
 

I wanted to find out if anyone here has changed the water impellors on a 496 HO? Dealer wants $500 to put the housing kits in 2 motors. Is this high or is it really that much work? Any info or help would be appreciated.

Thats about right very expencive housing

Re: Anyone changed impellors -496
 

Why do the housings need to be replaced? I thought the 496's had a brass housing.

Re: Anyone changed impellors -496
 

It is a pain in the ass to R&R the impellors on the 496s, but not hard to do by oneself. The brass housings should not be bad, and they cost around $300-$400 for each housing (they are brass), so I doubt they are replacing the housings.

I could see them charging 2 hours per motor plus impellors and seals plus shop fees.

I have twin 496HOs, and I have done mine a couple times.

Thaks guys! The motors are pretty tight...29 Outlaw. He said he would have to remove the rear bench to get to the starboard side. He checked them today and said that he didn't think they were bad yet. How often should you replace these?

I did mine on a 29 on my head. it can be done, but a pain in the a$$.

Re: Anyone changed impellors -496

Re: Anyone changed impellors -496
 

Your are not alone ...... here 546 hrs :eek: ...and never got a trouble.....but i will definitely exchange it this spring !!!!!! :D

Re: Anyone changed impellors -496
 

I have done lots and lots and even more in fountains, active thunders sonics and all the rest all upside down not fun......not to be mean but give him what ever he wants to do it and thank him because belive me you dont want do it....


if you suck sand in it or run it dry it could score the housing in which case you will want to replace both the housing and impeller, if you only replace impeller there is a good chance it will cavitate (Like a prop) and you will over heat

Re: Anyone changed impellors -496
 

The price seems fair. We way up north here in seasonal boating country change the impellers about every 2-3 years or every couple hundred hours.. Sooner if you run really dirty sany waters...

Re: Anyone changed impellors -496
 

Hmm, sounds like I have 200 hours to go. Cool.

Is this short water pump life only in salt or sandy water? I run in crystal clear highland lake reservoir water. Any idea the PM cycle for me?

Re: Anyone changed impellors -496
 

Ok, I succumbed to the fear, and I was right, had 200 hours to go. I went up and looked at it yesterday, no blades damaged no pieces missing, still pliable. Minor wear lines near where blades meet hub. Here goes 300.00+ I dont have. All sarcasm aside, my mech. even said 400 hours is probably ok. Merc recomends every year, but then they have an interest, just like the people who say you need to change your car oil every 3000, oil producers. So do what makes you comfortable, but this is your real world test, F.E.A.R., false event appears real. thanks, JC
