PLEASE HELP with these ram questions
 

I am trying to understand if there is any cross compatibility of drive rams between the TRS, alpha, bravo, etc. The deal is I have TRS drives and one of my trim cylinders is leaking a bit around the shaft seal, I have struggled to take it apart but I am guessing all that lovely salt water has welded the endcaps to the tubes. I have searched fleabay high and low and have only found TRS cylinders that are as questionable as the ones I already have.
I find it hard to believe that the TRS rams are only compatible on the TRS drives and the same goes for other mercruiser drives. My part numbers are 87411 and 87412. Does anyone have any specifications for the drive rams that come on some of these other outdrive models. As long as the stroke is the same and the overall length of the cylinder is the same then I can modify the pins, etc to work with my drives. I don't even really care if the placement of the oil line connectors are different as I am rerouting all the lines anyway. Any information anyone can provide on these other ram models would be greatly appreciated. Maybe someone even knows of a cross reference chart or something.

Thanks in advance!

As much as that sounds like a good deal, right now I am just looking for ram's. Thanks anayway

I regards to them being different, I figured the were but I would be very surprised if none of the rams that mercruiser made for there other sterndrive lines were not compatible from a stroke and lbs. of force. It just does not seem cost effective from a manufacturing standpoint to always have a completely new ram design for every sterndrive model.

There has got to be some cross compatibility! :mad:

Yes the TRS was built long ago . Theres also the job security standpoint plus the build it cheaper,faster ,facter They probibly commisioned a different manufacture along the way to supply them cheaper.You can probibly cut the nut off the ram and just buy a new nut , thats what I did on mine. If you cant I have a new ram casing only I could sell if you cant find any other way.

Hampstead, WOW, that's right next door! WHen you say you think you have what I need I am guessing you are reffering to some good shape TRS rams? Maybe we could hook up! :D

Thanks Man! I am going to keep looking, and I'm gonna see what fastek has. I will keep you in mind though I also have a couple more tricks I want to try to get the cap off.

I do have a question about taking these apart though, I have a clymer sterndrive manual and the manual states the rod unscrews from the actual cylinder, I have turned the rod about 50 times in each direction and nothing, Am I mis reading the book or are they referring to a different TRS ram? my ram on the cap has 4 1/4 holes in the end for a spanner wrench I am assuming.
