its hard to measure the length of the ram, as it is stuck in the cylinder, the ram diametre is 19mm or 3/4", the cylinder is about 11 3/8"long 290mm  to were the cap unscrews. the cylinder is not totally round, but is close to 49.5mm just under 2", we had it installed new in 2011. as I said in the first post the number on the out side of the cylinder, is 98718. cheers Don.

I am preparing to rebuild a pair of the same rams, not sure what number they have, but the Mercruiser rebuild kit is the same for Alpha and all Bravo rams.  Mine are not seized but I managed over the years tototally strip out the threads and break off some stainless screws in the zinc holes.  I have to replace the end caps and since I have to remove them to replace the end caps, I bought complete rebuild kits.  And I bought these great new quick change zinc system for the rams.  Iíll photograph the kits and part numbers for you so youíll know what to get to totally rebuild them.  Iíll even take pictures of the rebuild process, the only part that is tricky is if you remove the entire cylinder assembly and it can be tricky to re insert.  I wonít be getting to them for about a month but I can get you the part numbers for the rebuild kit and the rest of the parts I am using in short order if you want?

As for wethere or not it is worth rebuilding them please consider.
1.  If the chrome shaft is rebuildable it will cost less than $100.00 for the kits to do the job, a new Mercruiser replacement is more than $500 for each one.
2.  This is all predicated on the assumption that the shaft is indeed rebuildable, meaning it has no deep scratches or scars or corrosion that has eaten into the sealing portion of the shaft.  If itís no good Iíd look at used or aftermarket rams.  If the shaft is good and you can rebuild a Penn conventional 4/0 reel, you can rebuild these rams.

No experience with aftermarket Rams, but I know SEI is big in the Mercruiser aftermarket and they make replacement stern drives and related componenents for much less than Mercruiser.  As to how they operate and hold up? I have no idea and while I am always into savings, I am sceptacle of prices that are 25% of factory OEM, thatís just me though I do not know about these but I have looked into them myself.  I opted to rebuild mine before looking at replacing them.

To David, Joe and everyone that this may interest, my latest ram & cylinder update, I made up a jig to undo the collar, from the cylinder, the collar came out of the cylinder okay, then there was a cup that was left in the cylinder, I managed to get some info, from a mercruiser agent in Perth, he told me to use air presser to get the cup out, of the cylinder, so with my leading apprentice, Patricia, holding a plastic bag around the cylinder, I place air hose, over the intake end & the cup popped out so easy, what a lovely wife Patricia is, they do come in handy some times, ay, I cleaned the cylinder out & it looks great inside, so now to get a kit, the closest mercruiser out let, price for one kit AU$192.00, just for the kit, so now I am thinking, could any Hydaulic outlet make up a kit that would be good for salt water, cheers Don.

Further progress, as the collar was not turning on the ram, I took the complete unit to a Hydraulic, repare out let, he dismantled it, then told me that the seals had come apart, & there was metal inside the collar also some metal gouged out of the in side of the collar, the ram was good, but it was of set, so maybe bent, anyway I paid him for his trouble, that was much less than I expected, then I went around the corner to a mercruiser agent, the same one that quoted me $192.00 for the kit, anyway, I told them that I had pulled it apart, & the collar was in bad condition, also that I thought the ram maybe bent, so he looked at it & said the rams were offset anyway, so all good, he said the cylinder was all good, & I would not have to buy a complete new unit, as I could buy a new collar, anyway he gets out a new collar, with the kit already installed, So I say, I get all my services done here, & I am a broke old pensioner, so how much costs, he looks @ the computer, then said how would AU$192.00 the collar & kit all up, so that made me feel 10 years younger, more news coming when I get it all back together, cheers Don.

That would be awesome if your taking pictures.  I bought replacement end caps with the seal lists installed for 117USD for both cylinders.  Havenít touched them yet as my trailer is down, and the boats in the water.
Doh!

Thanks David & Joe, more progress today, I smoothed the ram rod with wet & dry sheets, started with 800, then 2000, & finnished of with 2500, cleaned it all up, then started placing it all togetherthe collar was hard to get on as there is a scraper rod in the middle of the collar, I had to hold that scrapper rod to one side, with a small screw driver, as Patricia, held a piece of wood on the collar & hammered it down,  had the rod protruding through the collar abot 150mm, 6", I was concerned that the collar was to tight, so I rang the outlet I brought it from, they told me that is okay being high pressure hydraulic they have to be tight, after some use the the collar would pivot on the rod, so we placed it all together, then up down a few times to bleed it, and it seems to be going good, I have to get the boat & trailer out of the shed, then back it into an area where I can get the leg down lower, wont get it done tomorrow buggar, have to go out with My mate and pull the rock lobster pots, cheers Don.& many thanks to all.

Thanks Wayne for posting the photos so quick for me & the members, yes Joe a spanner or jig, as you can see, part number 21 is a cap or I have been calling it a collar, it has 6 hole in it, 4 of them is to undo it, & the other two with threads are to attach the anodes, to the cylinder or cap, so the ram is 19mm 3/4" wide, I cut the U shape out @ 21 MM, then drilled the three holes, I then placed the blunt end of the drill bits through the jig & into the cap, gave the side of the jig a tap with the hammer, it soon came loose for me to undo it, the cap or collar has most of the kit seals & O rings in it, I went out with the boat on Friday, & the trim worked really good. so there you David, a walk in the park, cheers Don.
