I just bought an 87 rinker V180 with a 3.0 mercruiser in it. i believe it is 140hp but im not sure. I took it out for the first time last night and it sounded like something was rubbing in the motor. perhaps in the outdrive or somthing? i have never had an I/O before so i dont know if it is a uaual noise or what. can any help? I can only hear it when im in gear.<br /><br />Thanks <br />Ryan
