    1973 Mercruiser 140 HP Woes

    Yes its me again....Guess what just happened again? I lost my distributor drive gear again. I had about 10-20 hours on the new gear and it stripped of some teeth again. The firing order was mixed up (I had it set as 1-3-2-4 instead of 1-3-4-2) and it was out of time for 15 of those operating...

    1974 Mercruiser 140 clicking in lower unit

    I got my boat running the other day. It was hooked up to an earmuff and idling in neutral and I heard a clicking noise in the lower unit. As the RPM increase so does the clicking, but when I placed it in forward or reverse the clicking stopped. Is this normal?

    Position for kicker on '74 Sterncraft I/O

    I have a 1974 sterncraft that I just bought a kicker motor for it. It has a normal shaft and was wondering from looking at the pictures where I should put it. On the Port side there is a bracket for my future transducer. I was thinking above my trim piece because notice the curve in transom...

    I am thinking about buying a 1976 johnson 35 hp outboard for a kicker/auxilliary motor. I have a 1974 Sterncraft I/O and am wondering if this motor is too heavy for a bracket to be mounted on the back of my boat?
