Ok I hope I can explain this. I have the above mentioned 76 Merc 500 4cyl with a jet pump on it. Back earlier in the year I noticed that at full throttle it would occasionally blubber (don't know a better way to describe it) through the exhaust. It didn't really feel like a miss, just like it...
Ok guys here it goes I have a 1976 Merc 500 4cyl 50hp outboard, it has a switch box and 4 coils. Can an automotive tach be attached to this system and read correctly? The extra twist is that the tach that I have (why I am asking is because I already have it) also has a an induction lead on it...
