My 1994 Johnson 150 Ocean Runner is missing very bad @ 2500 rpms. I had replaced the Power Pac and Both temp sencors and the boat ran fine for about 3 hours this morning. Then when I started home, same problem @ 2500rpms.
New Chamion Plugs, new 10 mic canister fuel filter and fuel is fresh. I supect the SLOW mode is kicking in for some reason. Any suggestions.

Check the water pump and thermostats.

Did you get an overheat horn ??

Found my problem ,,, actual 2 problems.
1. warning horn no longer works. just old age i guess..

2. the sensor in the oil tank has shifted and now trips the warning at just less than halfway of the 1.8 gal tank.
It use to be set around 1/4 level, not sure why or how this moved but, I can live with the 1/2 tank warning for now.

Thanks for the note. H
