BenLubbs Posted March 23, 2012 Share Posted March 23, 2012 nate sounds like a timing issue. a timing light and a google search of the proper setting should be enough to get er done Link to comment Share on other sites More sharing options...

Side JOB Posted March 24, 2012 Share Posted March 24, 2012 The problem with points is u have to set the dwell with a dwell meter with are hard to come buy now adays. But if you put in an electronic ign should eliminate those issues. Link to comment Share on other sites More sharing options...
FsnMachine Posted March 25, 2012 Share Posted March 25, 2012 If you can put a pertronix ignition in it to eliminate the point it will save you a lot of grief.Check out this catalog. Go down to marins stuff and look for your motor in the mercruiser section. I have done this conversion twice now on a 6 and a v8.http://www.pertronix.com/catalogs/pdf/ptx/2010/ptx2010_ignition_conv.pdf Link to comment Share on other sites More sharing options...
