1989 Malibu skier w/ 350 mercruiser comp ski, standard points ignition, 4 bbl carb, 680 hours. I lost 800 rpm late last year, was hitting 4400, now I only get 3600. Mechanic looked at it, tweaked my valve adjustment (overheated last year, did valve job and new felpro gaskets) and said it was only advancing 24 degrees, whereas it should be advancing about 36 degrees at 3500 rpm. I took it apart and lubed the weights, seemed ok, but I checked again today and it is still advancing only 24 degrees.
Question, do I need a whole new distributor, or can I just get the guts? And if I get a new distributor can I just get an automotive one at my local parts dealer or do I need to get the Mercruiser replacement at nearly 3 times the cost?
