Thanks Phil! Should I just take the boat back to the mechanic that replaced the coils recently? Oddly enough, when I did get the motor back from the guy in Maryland, I took the boat out and it ran all day like a charm. during this successful first run, I did notice the Throttle was wanting to move back to slow position on its own, and it had never done that before…I didn’t think too much about it. But by end of the day of running the motor on my way back to the dock, the motor started sputtering, and shaking as if it was starved for fuel. It stopped running and I had to be towed to the dock. The next day at home in my test tank, I started the cold motor, and it started up on the first try. After about 10 minutes of running at idle, it started sputtering and shaking again as if it was starved for fuel, but I a motor won’t run for 10 minutes perfectly then all of a sudden start to have fuel issues, so I figured something was going on as the motor heated up. An old timer told me it was likely a bad coil. As the engine heats up, the coil heats up, & that was causing the sputtering/shaking. Made sense to me.

When I had the local mechanic here in Winchester Tennessee replace the coils last week, he mentioned the existing coils that the guy in Maryland had replaced when he installed a new powerhead were new aftermarket, but one had a crack in it. So, I’m starting to think that the guy in Maryland installed the new coils incorrectly, which caused one of the coils to go bad and crack, and the brand new coils I’ve just had replaced were installed incorrectly as well, and if I don’t get this fixed soon, the new coils will get broken because they are likely rubbing against the magnets on the flywheel as frankr mentioned in an earlier post….I don’t trust myself to take flywheels off, etc…Does anyone on this board know of any trustworthy old outboard mechanics in the middle/south Tennessee area that can fix this? I’ spent over $1,000.00 to the guy in Maryland to install the new 1958 powerhead, coils, carb rebuild, etc…and now another $400 to the guy here in Winchester that insisted I needed a carb rebuild, an electric fuel pump (I convinced him I didn’t need the electric fuel pump) and of course the new coils and points stuff…Thanks everyone
