Yanmar X0146648-01 End Cover
The Yanmar X0146648-01 is the factory end cover used in Yanmar marine diesel sea water pumps that use this part. It is the part that comes off every time the impeller is changed, which is exactly why it is the part most often found distorted or corroded.
Whenever the cover comes off, renew its seal and tighten the screws evenly in a cross pattern rather than working round the circle. That single habit is what keeps a cover flat for years, and it costs nothing.

Frequently Asked Questions
Q: My pump draws air rather than water. Could the cover be the cause?
It is one of the first places to look, along with the cover seal and the intake hose. Air drawn in at the cover joint gives a weak exhaust stream with a perfectly clear strainer.
Q: How tight should the cover screws be?
Snug and even, in a cross pattern. Overtightening is what bows the cover in the first place, and a bowed cover leaks however hard it is done up.
Q: Should the seal be replaced with the cover?
Yes. It has been disturbed and it takes a set in the joint, and a new cover on an old seal is a leak waiting to happen.
Q: Can a pitted cover face be cleaned up?
Light polishing is reasonable if it leaves the face flat. Anything that takes the face out of flat does more harm than the pitting did.
