1978 75hp Evinrude (75843C) tilt problem

[drose2878]

On my boat, my Evinrude won't stay up on its own when I tilt it back. Also, when I put it in reserve the motor kicks up out of the water. Doing some research it appears this me that my SHOCK ABSORBER bad. Does that sound right? It seem that the Johnson/Evinrude replacement part runs about $300. Does any know of a compatible part that cost less?

The shock is probably not the issue. There should be a lever with a black knob on the starboard side of the transom bracket. It is called a "tilt-lock" knob. That knob will move forward and aft so that the engine will lock itself in the down position-such that it won't kick up when in reverse. You can check out the original factory parts list on this website: epc.brp.com. You'll want to view the exhaust housing diagram to see the transom tilt/lock mechanisms. There also should be a trail lock mechanism that will hold the engine up when tilted-it's also in the diagram. This is for the 20" transom models. If you have the short 15" transom, the parts are somewhat different. There is a small lever at the front of the swivel bracket which will flip to the right/left to lock the engine. It's been years since I had my 1976 75 hp short shaft, so my comments are probably close to correct... You may get some additional comments from others.

if you have power tilt, then the hydraulic pump needs to be rebuilt. if it is calco, then just throw it away and replace both motor and pump with the prestolite version. If it is prestolite, then rebuild it or have it rebuilt. check ebay. Chrysler Force used prestolite and there should be plenty of valve bodies, valve body parts, and services. Rebuilt original is much more durable than new aftermarket so consider how long you want to keep boat when deciding.
