Re: Chrysler Power Trim/Tilt

yes. any system made for any three cylinder engine made before 1995 will fit your engine.

there was one rare instance of an odd-ball transom bracket used (but quickly abandoned) in the 1991-1994 timeframe. In yet another stroke of brilliant mercury engineering they designed a transom bracket with really cool trim pump mounts. Except ... the pump ended up underwater. Minor oversight and certainly not nearly as serious as so many of mercury's other flashes of engineering brilliance. What was different was that they actually figured out that it was a bad idea and stopped production. OMG! must have been a rogue chrysler engineer in their midsts!! Heaven forbid, maybe even a johnnyrude spy?

At any rate, other than that one brief design, any 3ram chrysler force trim will fit your engine. The 1990-1994 Eaton is the best engineered. Eaton engineers really shined on that design. But mercury engineers decided to use a cheaper ATF fluid (even though Eaton clearly says to use oil on side of pump) and the system eats itself up from the inside over time. BY far the best design. But you're going to have to rebuild it. Not a question of if, just when. 1988-1991 Prestolite is second best design. Same trim ram as Eaton but it lasts twice as long because US Marine didn't use cheap fluid. Pump will need rebuilding and motor will need new seals at 20 years .. so that's about another $160 in cost you need to plan on. 1970-1987 is as good as 1988 prestolite but with different motor. Motor is major pain to rebuild. Uses gaskets instead of seals so you just wait for it to break and then pay $110-200 to have it fixed. valve body still goes bad but slight variations of internal design tend to put less stress on check valve and it goes on the high side of 20 rather than low. Again, when it does go it is a more difficult repair than the 1988-1992 prestolite.

bottom line?
buy a freshwater system. favor the 2w eaton and prestolite as your first choice. look for a system with bleed down. It's going to bleed down anyway. If not this week then next. So don't waste your money paying extra for systems "that worked perfectly last year" or "goes up and down fine". Get a decent freshwater core for $200ish. Drop another $160 getting VB rebuild and motor seals. You'll be out about $400 with shipping and have a system that fits right into your existing clamps and runs like new. Probably the worst thing you can do is get into a bidding war on ebay and pay $350-$400 for a "hardly used, worked last year" system that has a really shiny paint job. It will still bleed down and you will still have to fix it and it won't end up any better than the $200 system.

Re: Chrysler Power Trim/Tilt

try craigslist first. They don't charge 15% fee. Ebay is no longer land of bargains. They have priced themselves out of being a good auction site. Too many of their auctions have reserves and auctions with no reserve are usually bottom of the barrel quality. Ebay has become the internet flea market.

There is only one system worth looking at on ebay right now (06/03/09). If you look at motor, the top nut is facing wrong way. That means it has been serviced at least once. So you can figure that the motor probably does not have any internal rust and that it has recent seals to keep it that way. That's the next best thing to an actual rebuild. So bottom line on this system is that you're only looking at $130 in repairs (valve body rebuild to stop bleed down) and the thing is probably good to go for another 5-7 years. There is no rust around mounting eyes. There is no white deposit around transom mounting holes ... this is a clean system.

Can't say the same about other ones ....
The one from NJ has oildyne pump and has probably seen saltwater use. When (and if not already) something breaks it will cost more to fix than throw away.

The one from california is insanely overpriced. $550 to buy a system that's going to need another $250 in pump repairs within a year? That's just plain nuts. You'll be dropping $800 in cash and wasting six hours of labor taking pump back off next fall.

The white one from PA is a high risk system. Paint doesn't peel off just because it got tired of being the same color. Look closely and you see rust around mounting eye. It is possible that this is a freshwater system in great shape with just a little surface rust around mounting eye. Throw $320 at it and it becomes brand new. It is equally likely that it has corrosion damage and will cost over $400 to fix.

when looking at ebay, you have to be extra careful to avoid systems that show corrosion. It is retarded to think that you can buy a 20 year old system and it won't need repairs. First off, if the boat had been properly maintained then the engine wouldn't have blown up and the trim system would not be listed for sale. Second, you wouldn't expect the rubber on your tires to last 20 years just because the paint is shiny and you hardly ever drive. Whether you use it or not rubber gets old and breaks. Same is just as true on boats as on cars. If you buy a trim system that has been used in salty/brackish/polluted/acidic water then it will cost you $100 to $250 more to fix than a freshwater system. Look for white deposits around transom clamps and rust around mounting eyes. Avoid galvanic corrosion like the plague.

great!!! thanks for taking the time to find that. i have been looking on craigslist as well and have not found much in the way of any chrysler parts so far. i think i am going to try and win the one you found on ebay, if the price doesnt go to high like the other one you were talking about. thanks again
