Thanks for the help all. I bought a similar Johnson Ocean Runner 200 HP model and swapped parts. Up and running BUT, now trying to trace high speed vacuum leak or cracked fuel pickup in '78 Mako 23.
I am still baffled by no spark at all - flywheel magnets re glued in with only a small chip in one. I really need somewhere to go from here. Sounds like flywheel replacement, but wouldn't it create a weak spark even right now?
I truly believe this is a kill switch / interrupter issue. The boat...
Excellent! This is good intel and the last part of the electrical spark generation system that hasn't been replaced. Multimeter is not showing 120V DC (more like 90-110V DC). Any recommendations on where to get a remanufactured flywheel?
I didnt replace the starter - I replaced the STATOR and Timer base (both under the flywheel, because I saw melted goop from a 30 year old stator. I was trying to restore a spark and the CDI tests showed it failed miserably re OHMS.
I’ve worked on this motor before, I have a similar 1993 ocean runner 150 hp and have no problem with the electrical system as it uses OIS.
This is when it stopped working.
I had to change the water pump as the boat has been sitting for years.
The boat ran great with the new water pump. I only...
Trust me - I dug deep (think I reached the end of the internet) but couldnt find how to test that specific voltage regulator/rectifier (oem 0584093 / 0439561)
Looking for any helpful guidance. 1993 Johnson V6 150 – replaced water pump and impeller. Found a lot of salt deposits in and around the water housing manifold. Don’t know how to remove the intake screens to check if there’s anything collected up in there. Since the engine overheated is no...
Haha, I hear you. It still turns but I think its only rust holding it together. I hate this damn engine. Concerns noted and will have to replace (which would likely break more rusted bolts...) or come up with some sort of rig/winch/strap to secure to the arm. Either way, not good.
Yes it is a looper - used automotive gasket maker (fuel resistant) for now until I can get a newer engine. This one is starting to alarm after 4k RPMs now. Still determining if gas restriction or overheat. It does allow me to turn it off and right back on without alarm at 4k RPM. Starts as...
