Against my objectiins my buddy bought an 85 boat with a 3.0 omc inboard. He approached the boat as a car and decided to do some tuning and now as it way out of time. I spoke with my mechanic in another state and he gave me basic information. The mechanic stated that if their was a plug or dangling wire on the distributer it was a matter of grounding those out (putting in base time) and timing. Without either of those to set the timing you need to put it in base time, set dwell, set ignition speed them time normally. Neither of us know how to do these things. My buddy originally tried to adjust timing 6-8 degrees but everytime he brought idle back down it died. He called me and i made the call to the mechanic who confirmed my opinion that I have no idea. Any suggestionhow to get this back to running condition and please be as specific or explanatory as possible as in do this and then this. I have never messed with dwell or setting ignition speed.
