I have a '92 120 Johnson that has no power. I re-built the carbs but the problem still exists so I preformed a spark test and found that 3 of the 4 leads will show spark at a .02 gap and one lead I had to adjust the tester slightly under .02 to show spark. The QL78YC plugs are gapped at .03 so...
I lost my neutral and reverse somehow yesterday and I'm not sure why. I am now always in forward gear but I have no problem starting the engine. I am thinking that the throttle control is sticking but I am hoping for some advice before I just start taking things apart. Any advice is appreciated.
I have a '92 Johnson 120 which has run very poor since last season. It seemed as though I was losing cylinders and running in the driveway with ears on was producing big blobs of oil. Eventually the boat wouldn't start and a spark test showed no spark from any coil so I replaced the power pack...

I have a '92 Johnson 120 V4 which I've owned for 3 years now and has always run great until this year.
A month ago it started to lose power while in use. Basically it would go from 50mph down to 40mph...
