Re: ’79 OMC 9.9; grommet time?

I have plenty ugly to say about the 1974-76 models, but don’t have enough experience to comment on your ’79. But as for your powerpack, the simplest test is to see if it has spark (on both cylinders). If it does, the powerpack is working. They either work or they don’t work. Don’t fix it if it isn’t broken. And I’d say that overall, they are more reliable than the points system. Don’t fear science.
