I recently purchased a 1973 18ft starcraft i/o offshore. It has a 120 hp mercruser in it. It was a project boat that the seller lost interest in. All I wanted was the trailer the boat was on. I was told that the i/o ran great but the tilt/trim did not work. He was right, it runs great. the boat is completely gutted including the i/o cover. I have very little invested in this boat. the hull is prefect just faded paint. Is this boat worth restoring and what kind of performance could I expect from the power plant. Is an i/o to ob transplant feasible? thanks, pappaw
