Johnson 115 1995 Question

Hello Randy, 

Its Dave from Michigan. I just had a few questions on this boat I just picked up. It has a Johnson 115 on it (1195), looks like no spark from all cylinders.  Where do I go from here, is it the power pack everyone is saying?  Anyway to tell for sure, know its kind of a general question.  Also, trim unit makes noise up and down, no movement either way?  Any help would be great, thanks in advance !!!!!

Dave, 

OMC made two 115hp engines. The 60 degree loop charged version and the old crossflow version then called the "special" or spl. Both had CDI packs that could be bad in your problem description. The cross charged motor I would say is the pack as any other problem like triggers or coils taking out all 4 cylinders is unlikely. The stator could cause this type of failure but I haven't had an OMC stator go bad in so long I think I was in my 20's then. The new 60 degree motor had some problems with the trigger assembly and they were shipping a new CDI box and trigger together. One was causing the other one to fail. At any rate, I go for the CDI box as 99% of the time on an OMC with no spark on ALL cylinders it's that.  

Most importantly I'm assuming that you know the key switch and the wire harness is good. If the key switch is shorted it can cause the engine to have no spark. Spins over but the switch won't turn it on. 

The trim could be as simple as the tilt release screw is loose. It is located on the starboard clamp bracket and has an arrow showing which way to turn it to release. Turn it the other way and try it. If that doesn't work check the fluid level and if it is ok then you have an internal valve problem and a good dealer will need to look at it. 

Hope this answers your questions, 

Randy
