Location: Mauston, Wisconsin | Greg, A couple possibilities besides a bad starter.
1. Bad battery - "Fully charged" is really not a good quantifier as to wether the battery is good or bad. An easy way to eliminate the starter as the problem is to use a known good battery and a set of jumper cables.
2. Bad connections - A whole lot of car batteries are replaced here in the midwest during winter, a good battery terminal cleaning would probably have fixed a lot of them, especially on older cars. I would first suspect a bad connection at the battery or the starter or in between, and I would check these first. Its also good to clean & reasemble all battery connections at least once a year (But, leave the battery negative lead off until you're finished- safety). Boats are great places for corrosion of electrical connections. Yours is 20 years old. Start at the battery and work your way to the starter.
3. Starter Solenoid - Sometimes they are built into the starter - but my 1989 Johnson 150 has a separate solenoid. The solenoid connects the battery to the starter when you turn the key to start. Burnt solenoid contacts could also give you similar symptom's.
Good luck!
