Johnson Impeller Housing wear

[carbineone]

Hi everybody,new here and have a 1963 Johnson 28HP Super Seahorse I am going to use on my little 10' GW Invader Speedboat.I ordered a new impeller and seals but when I took the bottom end off my wear plate has alot of wear and so does the pump housing.I have unable so far to find a pump housing for the early 28HP or a wear plate..If someone can direct me to where I can find one that would be great.Also is there a chance it will run OK with just the new impeller and some wear on the housing and plate...Motor runs beutiful otherwise so I do not want to mess it up with overheating.is there anyway to make a new wear plate maybe and maybe smooth the housing? Thanks and please help...Bruce

Re: Johnson Impeller Housing wear

the water pump kit comes with a new wear plate.

Your impeller housing is metal correct?

Re: Johnson Impeller Housing wear

Repair kit with housing from any authorized BRP dealer is part #0379774. I see some on ebay search for "379774".

If you just want the housing alone, it's part #0303831.

Yes the impeller housing is aluminum..I cannot find any whole kits..Besides I already bought the seal kit and impeller so really do not want to buy more stuff that I already have..Will search Ebay and see what I can find..Whats a authorized BRP Dealer?Thanks

Thanks,paid 35.00 buy now for the whole kit and if anyone else needs one he has one kit left after I purchased mine.Seems to be a good price...I almost should just buy both as they are free shipping too but can only afford one....Bruce

Re: Johnson Impeller Housing wear

That stuff is all available from any Evinrude dealer. However, you probably got a better price on e-bay.

pump housing is 303831
plate is 303866

EDIT: Heck yes you got a better deal. The list price for the housing is $71.40 and the plate is $32.13.

Re: Johnson Impeller Housing wear

One other question if you guys can tell me..With the bottom end removed for the pump replacement can I start the motor without harming anything for a short time..I want to check some other things on the motor that require a temporary startup.Does not need to run for more than a minute or so to do this.Parts will not be here till next week to put it back together and would like to get a jump on a couple other minor things..Thanks

I overheated and seized a motor (1969 18hp) in less than a minute.

Be careful of a worn housing. They can start to develop small nicks that start cutting the rubber:

You wouldn't think so by looking at it, but yeah. entire outboard corroded from the paint in. I have seen housings that are worse, with razor sharp edges, the one pictured isnt even that bad.
