I have a Yamaha 242 Limited S.
The port engine is stubborn to crank over. It usually takes several tries and several seconds to catch and turnover. It also pulls the battery down very quickly, usually to the point that the other motor has to be on and the battery switch be in the parallel position. Often when it does turn over it backfires. This hard cranking happens 80% of the time and is less common when warm. once it cranks it runs rough (surging) for a few seconds. After that it runs great and no issues.
I have checked the timing and the spark plugs (good gap and not fouled), no issues. Batteries are healthy and the starter sounds strong.
I suspect maybe a bad ground, I have put an old set of jumper cables on the engine mounts and exhaust over to the other motor to see if that helped but didn't really notice a difference. From my studying the Ground wire is on the started under the exhaust and wanted a second opinion before I pull the exhaust off.
This issue started when i pulled it out last summer and only got to run it a couple times. Ran it last weekend and the issue remains.
Any thought and what else could be causing this and/or what to check?
