Have a 2002 VP DPSM outdrive with SX MHP transom housing. I'm not thinking that makes much difference for the question with trim cylinders, but wanted to provide anyways...
Have been experiencing the unwanted oil slick whenever trim is adjusted up or down at docks and am pretty sure the trim cylinders are leaking at the exit end of rods. Last spring when I launched I noticed some drips on the cavitation plate, but didn't have much concern. Has definitely gotten worse as season has progressed.
Other threads are talking of an Ebay "kit" to the tune of $150 and also I have seen information about VP parts to do this. I blieve mine are NOT of OMC vintage and want to know for sure the proper avenue to go for the necessary parts. Pretty confident I can perform the work, but want to be assured I am getting the proper parts before I begin.
Can one of you very knowledgeable gents please point me in the right direction with link(s) and information?
Thank you!

Your signature says you have a DPS-A drive yet you say DPSM they are very different.

Tag on port side of drive states DP SM 1.95
My mistake on the signature.
Any information regarding the cylinders?

Ive rebuilt the sx-m cylinder's they are very simplistic. It would be worth your time to try and find a shop that works on hydraulics they may recognize the seals and if so its a 5 minute job. With that said inspect the ram closely if there are nicks or scoring that will make them ..junk.

Can you tell us where you obtained the parts to rebuild your SX M cylinders?

Thanks Tail Gunner,
So is that the kit that supposedly (per some other posts) doesn't last too terribly long, or will it get through two or three seasons, making it well worth the time? Does it have all the necessary seals/rings/etc...

Take Care!

It's been two yrs no leak's. The fix is very simple but the ram's need to free of damage and the seal's need to be installed correctly there is a lot of pressure at work there trying to find a way out.
