    Flywheel Magnets - Should I be Concerned?

    Pulled my flywheel last night ad found a small chip and some scraping under the flywheel and along the edges of the stator. I think it's OK but I'd like a second opinion. The chipped magnet is isolated to the one magnet pictured and the scoring pictured on the stator is the worst spot. Many...

    1995 150 Johnson 60 degree looper. Just removed the power head from the exhaust housing. I've removed the electronics, carbs, intakesw and reed assemblies. Now I'm down to the flywheel. It is attached with 5 bolts. I've removed them and there is light corrosion on the crankshaft. I thought...

    If I have twins and one dies.....

    I know lugging an engine is bad news. My boat running on one engine runs about 30 mph at 4300 rpm, on two it runs 47 mph and 5800 rpm Since I have twins, if one dies and I run 50-60 miles will it damage the good engine?

    Erratic Timing all cylinders

    One of my two 1995 150s has a sneeze at idle it's power output at WOT is not what it should be. While diagnosing things I hooked my modern inductive timing light up to it. And noticed the light flashes were not evenly paced as youd expect. I first blamed the timing light. Then I hooked it to...

    1995 OIS Timing Wheel removal

    I have a 1995 150 Ocean runner with the OIS system. My issue is not with the running of the engine, it's the starting. The starter sometimes makes a screeching noise as it's cranking. The starter/Bendix are two separate parts and to get to the Bendix I need to remove the flywheel cover. I've...

    Motor automatically drops!

    My buddies Mercury 1996 150 will automatically drop when tilted up and RPMs exceed x number. Is there anyway to stop this behavior? It really sucks in skinny water when you need to go and the engine drops into the sand.... SW Florida has lots of shallow areas.

    I have twin 1995 150's One - J150NXEOM (Counter rotating) sn G03792920 has a really annoying squeal when it's started.

    Looking to replace my 10 yr old primer bulbs and surface hoses. The iboats products are all under $10.00. Are they as good as the factory ones I'm replacing or is this a Johnson part I should be getting? Thanks! Richard
