A couple of months ago I bought a boat with a 1988, 50HP Force (by US Marine) outboard. The second time I used it, it was running great, but I backed into a clump of cat tails and stirred up some mud. On the way back to the boat ramp I noticed that the engine was lugging down. My friend looked back and said "Sut it down,it's smoking". By that time it was too late. Apparently, it had sucked up trash and clogged the thermostat. I tore it down and it had a galled lower cylinder.

I found another 50 HP force outboard made by Mercury. I believe it to be a 1992-1994 model. I can find no data plate.

My problem is that the cable hookup on the engine is different and there is nothing to keep the outer cables from moving along with the inner ones. There must be a keeper that I did not get on the newer engine. I've tried to find the part on Iboats, but have had no luck. I attempted to use the connectors from the other moter, but they will not fit

Also, the wiring is completely different. The first engine had all the wires from the control box tied into a bar type connector. Wires screwed to each side. This other engine does not have that, and I can not figure out where to attach all the wires. The newer engine has a "CDI" box and some other electronics which are different.

I ordered a "SELOC" manual for Force engines, but is difficult to understand how to go from one set of wiring to another, and there is no picture or reference as to how the cables are secured.

I would appreciate any assistance form knowledgeable pople on this forum.
