I have a 88 Johnson 150 on a boat i just purchased that was so say "water ready" it will fire up and run great at idle but when you launch it it bogs when you give it gas. After a little searching with my minimal boat repair skills i noticed that cylinder 2 on one side of the engine and cylinder 3 on the other side isn't firing. boat has new plugs and someone replaced the stater on it recently it still had the repair shop sticker on it. Did some reading online and seem to think it may be the powerpacks but what is the chance of both packs going bad and no allowing one cylinder on each to not fire. is there anything else i should check before dropping the bank on new packs. I also swapped some coils around witch didn't solve the issue so im sure the coils and plugs aren't the problem Thanks
