Any "How-To" Rebuild B1 Drive Trim Pump Out There?
I searched here and didn't find one. I'm looking for a how-to on rebuilding the drive trim pump of a mid 90's B1 (OF813384) using the Mercruiser kit #18545A1. Just went to the boat after 10 days and the SB drive has sagged ~3" in comparison with the port.
Thanks for any help you can lend!

On my old '93 bravo boat one drive would bleed down. I rebuilt the pump and it solved my problem, and created another. The rebuild kit had updated valves so it would trim faster than the other side. No biggy, just rebuilt other side.

I've found the rebuild kits for the pump for $60, the ebay pumps are $300.
Where did you find the rebuild directions?

Also did you rebuild the pump yourself and did you happen to find instructions to do so somewhere?
Thanks

I just bought the rebuild kits for the RAMS from CP Performance for 14.99. They are a supporting vendor and they arrived in a couple days. Used a PIPE wrench to pull the ends cap off and repainted when all was said and done. Rebuild time is about 10 minutes. Clean-up and paint time is up to you!! There are some YouTube videos on rebuilding them but used compressed air to get the back stopper out so that you can put the new O-Ring on that, when you unbolt the spring watch out for the small ball bearings so they don't fall out, and be sure to put the O-Ring back in under the bolt on the back of the rod.
Rams can definitely fail with no outward signs.
