I have a 98 bayliner with a 3.0 mercruiser had a problem on the water the starter went. Had it towed fixed the starter and now it wont run. It cranks and all but wont start. And the only plug that is firing good enough to get across a plug is cyl 2. The others are getting enough juice threw them to light a tester light but not strong enough to fire a plug. My guess is its the ignition module and I have one on its way. any ideas what it could be if that dosent fix the problem?
