Hello,
I recently bought a boat with a 1983 mercury 50 hp 4cyl. I replaced the stator and trigger, reset float height, and replaced carb gaskets. it started right up and appears to idle nicely. I took it to the water today and hooked it uo to my tiny tach to fine tune the carb . I noticed that it is reading 2000-2500 while idling but it doesn't sound at all like it's that high. I put it in gear and took it out a few hundred feet while pating attention to the tach. With the throttle about 3/4 down, the tach read 4000-4900 and it the boat was barely moving. I was thinking this may be a spun prop but I took the prop off and it appears to be fine (from what I can see)... Should I have reset the timing when I replaced the stator and trigger? I'm thinking this may be a timing issue?
