I have a lot of questions. I just bought this boat and don't know much about i/o's.<br />I have a 3.0 4 cyl. 89 omc cobra. I can set the timming to run at an idle or high rpm but don't seem to be able to do both. I don't know what advances the timming.<br />What is the shift assist and what does it do?<br />Could a chevy car distributor with electronic ignition be used. I have been told you can drill the carb. to pick up vacum for the timming advance for this. <br />Just a lot of questions and not many answers. <br />I am a fair mech. on older cars and have some skills.<br />Thanks for any help
