I just came across a project boat well it was given to me it's a Renken 2100 it has a good hull and top side the out drive is a volvo 270 that seems to be in good working order the boat is a 1984 the motor is a volvo AQ125A that is in need of alot of work I think it maybe frozen or blown not sure my question is is this motor worth rebuilding or is it possible that another type of motor will mount on to the out drive unit.this is my first I/o so I do not know much about it. If anyone could help me I sure would be thankfull.
