I'm kinda new to this but the motor is a 72 3cyl outbord elect shift 55HP, the prob i'm having is when i take it out, it starts no probs, in Nutral you could rev it till it blows and runs like it allways had, but when you put it in gear and it maby turns 1000-1500rpm and thats top speed and it never planes out, verry verry slow, when it first started happening i drove it thrue a few tight S's and it would take off fine, if anyone on here could point me in a direction to be lookin i would apriciate it, i do have a manual just looking for and idea as to what i should be looking at.... thanks
