Just bought a 1990 Maxum with a Force 120 Outboard. Before putting it in the water I had the local marine mechanic take a look at the lower unit and run the system with muffs. Everything looked ok and ran well, although water throughput was lower than he was used to seeing with other outboards. About a half mile out of the marina (very slow throttle) a steady alarm sounded. It ceased immediately upon key shutoff and after I gave
it slightly more throttle. There was no smoke or sign of excessive heating.
Question 1) Is heat the only cause for alarms on a Force 120, or is low oil in the prop area also?
After another half mile engine cut off instantly, as if there was an electrical or fuel shut off switch. The prop and flywheel turn freely so there is no seizing. I am wondering if I am dealing with 2 seperate issues. One being pump impeller or clogged cooling, and one being a fuel problem. It did sit for about a year with a full tank of gas stabilized with marine stabil.
