Evinrude / Johnson Power Tilt Trim

[Frankenstein]

I've got a 1973 Evinrude 115 and with a bum tilt/trim. I believe it is the CALCO unit (5 screws on the pump) and the motor is missing.

Right now I'm looking at ~$250 to get a new motor if the resevoir only is enough for the core charge. I haven't really tested the pump yet to see if there is a problem there, just shopping around for best case scenario.

Would you guys go this route? Or is there a different motor/resevoir/pump I could run? I don't mind fabbing new hard lines out to the pistons or anything like that if it saves money.

stringer pumps (motor + valve body) are a drop in replacement for calco. they are usually found on ebay in the $50 - $150 range. the original OMC I/O trim motor will be water-resistant. The Evinrude trim motor needs to be waterproof. slather the OMC motor with some liquid plastic and run it until the motor dies. then keep the valve body and put on a waterproof chinese motor.

problem is that he has a calco pump (aka valve body) and needs a calco motor to make it work. E/J shipped two flavors: Calco and Prestolite. They are interchangeable as long as you interchange both the motor AND the valve body. Prestolite has stood the test of time with a healthy market for repairs and parts. Calco was a solution looking for a problem and died a quiet death 30 years ago.

Re: Evinrude / Johnson Power Tilt Trim

My question is not where to find the part, its API model PT113N (which DB electrical does not carry).

My question is assuming the pump is good would you put another motor on top of the Calco pump or mount a different unit.

RRitt I'll check out those stringer pumps when I get home and have access to ebay. Do you have a suggestion on a product for the waterproofing? Would something like epoxy resin do the trick?

a $5 can of plasticoat and a disposable paintbrush would be much easier than epoxy. maybe even a better seal since it would not crack with vibration. I bought a 8" tall tin of brush on plasticoat about a year ago. the chinese motors are terrible about using steel through bolts and steel sealing washers - which is a big part of why they only last 1/2 as long as the oem motors. so i coat them liberally whenever i see them. i still have about a third of a can of plasticoat. it goes a long, long way.

and, for whatever it is worth, if you are going to buy american then head for ARCO or Sierra. I've never seen them put their name on a lemon. ARCO in particular is almost always the best product available. I've had a lot of trouble with the API implementations of prestolite and out-of-tolerance end play on the armatures.
