Crank sensor force 125 outboard

[gamewarden0083]

I recently purchased a 1988 bayline capri with a force 125 as a play boat i plan on upgrading the outboard when ever the whife will let me but for now i am working on getting the existiing motor running. when i bought it i was told by the previous owner that the crank sensor was bad. i have been looking around for anyinformation i could find regarding a crank sensor but havent been able to finde anything so today i purchased a manuel but i am curious if they call it something else or if anyone can offer some help on waking up my outboard its been sitting for about 6 months uncovered. there is a little rot on the floor so i need to check the foam underneath and the upholstrey is destroyed but the hull and fiberglass all seems in good shape ive not seen anyproblems with the transom. if anyone has anypointers. i have worked with boats for the last 3 years mostly inboard jets and 55hp outboards so this is a new beast for me.

My guess would be the trigger assy. Hard to say since the previous owner doesn't sound like he has much experience with the Force motors. I wouldn't take his word for it though.

The only assunption you should make is that the previous owner did not know what he was talking about.

Start from scratch. If the engine has a man overboard switch or dead man's switch, be certain that the clip is inserted. Then remove the white wires from the terminal strip on the engine near the starter. These are the stop wires. If you now have spark, the problem is in the ignition switch.

Check for spark at the plugs and work backward. First clean or replace the plugs. If there is no spark on any plug, it is likely not the CD boxes or the trigger.

So: If removing the white wires did not give spark, then starting from the stator, check for continuity on the ignition windings of the stator. If that proves ok, the check each individual trigger pair for continuity. Then check the CD boxes and finally the coils.

Smart move in buying a manual. It should give the testing procedures and test valuse for the electronic components.

Bayliners were inexpensive boats for the masses. That said, the hulls of the older boats are pretty much bullet proof but heavy. The sore spot on Bayliners is that they did not use Stainless Steel hardware in all applications. You will find many screws, snaps and nuts rusting away.

The Force engines they put on them were pretty basic engines and not very economical. They burn through fuel like turbine engines. However, their simplicity makes them long lasting and reliable if maintained properly.

Many members own 125's on this forum and we have suggested much trouble shooting and repairs. Take the time to search the forum using different terms and you will find a wealth of information.
