i have a 77 mercury thunderbolt 500 50hp engine. i was told it ran good when i bought the boat. i finally got it to run, but when you move the gear shift all the way forward, it does not rev the engine till at least 30 seconds after. and it barely revs the engine at that. the prop spins, and you hear a clunk when puting it in gear, both forward and reverse. when i put it in reverse, the engine revs very high. i do not have any experience with out boards, as this is my first boat. im guessing the linkage in the motor needs adjusted, but dont want to mess with anything till i get advice from someone who may know what it is.
