Evinrude 4423 slop between pump assy./pivot bearing.

[unsafeatanyspeed]

Greetings knowledgeable motor folks! I recently obtained an Evinrude #4423 Sportwin that I have no prior experience with. Theres a gap between the pump body and pivot bearing that you can push up to close. The body moves, not the shaft inside it. It also has some port and starboard slop. Is this normal for this motor? If not, is it a huge undertaking to remedy?
Thanks for your time,
Doug.

There’s some fiber liners in there and / or bushings
that may be worn out. I’ve added shim stock behind
the liners before to tighten things up.
There’s also suppose to be a spacer washer at
the joint you’re showing…….. is it there?

Prepare to be boarded!

Thanks Buccaneer. The pump body washer is there, but it doesn’t appear that the pivot bearing spacer is present. Do you know what type of material the spacer would be made of? Perhaps it’s something I could make.

Dowel pin 200735 is probably missing, prevents the sideways motion.

If you have too many, AND not enough, you're a collector.

Thank you Kerry. Now when my wife gives me a hard time for being in the garage too long, I can say ” Kerry and Buccaneer made me do it!”.

Doug, I’ll look in the garage tomorrow and see if I can tell how thick the washer is,
and what it’s made out of. I have a froze up parts motor, but not sure what’s
all there on it.

Prepare to be boarded!

That’s mighty good of you Buccaneer! I’ll wait to hear back from you.
Thanks,
Doug.

Doug, in looking at your photo again, I think I can see both the spacer and wave washer
on yours. It may be that whatever takes up the weight on the top side of your
transom / swivel mount is worn down.

Anyways, I looked at my parts motor, and took photos. The spacer washer
is 1/16″ or less in thickness by looking at it.
I suppose you could add spacers in the bottom to take up the slop, or perhaps
cure what’s ever ailing it on the top side of the swivel mount.
You really won’t know until you tear it apart.

Well Buccaneer, I certainly thank you for your time, effort and knowledge!
I think you just spoke the most beautiful, yet dangerous words I could here. “You really won’t know until you tear it apart”. I’m waiting on a service manual I ordered cause I know enough to know what I don’t know, but impatience is getting the better of me. I’ve never worked on that part of a motor and am fearing the unknown. Of coarse, I could tear it apart and if I get in trouble I’ll know the service manual will eventually arrive!
Thanks again Buccaneer,
Doug.

So I took everything apart to see what I could find…and clean. Everything looked good and was where it was supposed to be. When I got to the steering handle I noticed the shock absorbers and thrust plug looked a bit worn down. So I took some 1/8″ rubber gasket material I had and placed some pieces under each. After reassembly with a firm snugging on the pump body clamp screw, everything is solid as Sears! Even the port and starboard play is gone. Thanks for the help gentleman!!
Until next time,
Doug.
