Hi all i was given a Renken 19' boat with a volvo aq 125 and 270 out drive.This boat sat for 5 years uncovered and with no motor cover. I drained the oil and a gallon of water came out along with the oil.The motor does turn but don't know what damage was done. Before i get to involved in this i was wondering if this is a auto based motor and if so what year and model could i get one from.This looks like the 4 cyl that came in the volvo 240 the B17? But will it interchange with the motor in my boat? The out drive looks to be in very good shape but needs a prop.Any help would be great. Thanks Larry
