1969 4HP (model 4906B) - equivalent part impeller housing

[Good Trout To You Sir]

Preparing to service 1969 4HP (4906B) with unknown previous history. Anticipating the worst.
Seeking source of equivalent part for impeller housing or complete pump repair kit w/ housing. Perhaps under different part number. Prefer to match to Sierra if I can.
Impeller housing: 0310344. Pricing.....yikes!

Inspect the housing first !

Original water pump repair kit (complete) was part # 382797. That is replaced with a more modern and better pump #0763758.. The new one has a plastic housing with stainless steel liner and a smaller impeller. Because of the SS liner, in the future all you will need is a new impeller. Besides, they pump better.

Are we sure that is the correct kit for the 4 HP motor ???----I thought they only used 2 screws for the pump housing !!

Many thanks, F_R! Trust what you say, and am interested in recreating the thread to your result. New to this, so used manufacturer site and part#s from the old diagrams. They are different from your part numbers. What source(s) should I be using?
Presumably the drive shaft is seized in powerhead. I have reviewed what I can find on methods to remove. Absent solvent application & soak method,nearly all ideas call for removing lower leg prior to pulling, hammering, etc. Anything I should be considering as a pulling-type apparatus suitable for use in the small space where drive shaft is exposed after lower leg is loosened? Thanks again.

According to shop evinrude the pump kit number is 379770.... The one in the photo is 0763758 and it has four screws as racerone pointed out...

Good catch. My eyeballs must have been crossed when I looked at the posting. My info was for a 6hp.

Complete water pump kit for a 4906B is part number 379770. Price is awful. As said earlier, make sure you need a new housing first.

I saw a couple kits of 379770 for 45$ US plus shipping... Just need to look around.... And yes just the housing is listed at much more then that....

I have a couple of the 6 HP kits on the workbench right now.----The wee error was easy to spot !
