Rebuild or Replace trim pump
 

I have a pre-alpha trim pump for my TRS drives that is leaking. I believe the leak is from the shaft seal as it appears the oil is coming out around the electric motor. This is the style of pump I have - 4 of them. I'm not finding any replacement seals and not sure the seals on the motor shaft are replaceable. Anyone done it? These have been sitting for a LONG time. Only one is leaking but when I took it apart there was a little sludge in there so I will want to pull them all apart at a minimum and clean up. https://i.ebayimg.com/images/g/VVkAA...q/s-l1600.webp

You have a prestolite trim pump there. The only thing I see on BAM's website is the thrust washer
Genuine Mercury Marine parts, large inventory, fast shipping
Part 5

Since you have 4 of them on a TRS boat (2 for the drives and 2 for the tabs) you could upgrade just the drive ones to the newer clear plastic reservoir.

Tim Douglas AKA Fullforce has a bunch of pumps and he's near you in Olmstead Falls.

I found one on FB marketplace close to you

Pm Full Force on here he probably has a few good used ones and he’s in Ohio.
