I hope someone can help me i've given up- so has my boat mechanic.. I have a 1975 Merc 500 50hp,The engine starts right up the only thing is it only goes about 15 mph.. I've cleaned the carbs and put new seals in it(i didn't replace the floats but they look pretty good)..I put new fuel pump in it I think i installed it right( when i squeeze the primer when its running wot it will want to stall out) also when i run it,it seems that the primer will go soft after a few minutes of wot..also new plugs and changed distribitor..my questions r as followed
1. The compression in all cylinders is about 110,Can there still be something wrong internally????
2.Could this still be a fuel problem if so how???
3. Could the switch box be related to this?? any suggestions would be appreciated thanks Erik
