Check, recheck, then check things again. It sounds funny but it does work. My theory is when I’m on the water, I have to be as self sufficient as possible. That means, at least 2 sources of moving the boat, if not three.
It amazes me that people go out unprepared and then get mad because their boat/motor fails. If they took the time upfront to test, maintain, and run their equipment, they wouldn’t find out on the water that the motor needs new plugs or the gas is bad.
I have a 16’ Lund that is powered by a 15hp 2 stroke Suzuki, backed up with a 30# Minnkota trolling motor, backed up with a good set of oars. Depending on where I am fishing, (sometimes electric only) there are either 2 or 3 power sources on the boat.
However, (knock on wood) nothing has ever failed me because I make sure I am well prepared for the inevitable. The motors are always test ran prior to leaving the driveway, there are always extra plugs and tools on the boat, and the battery and fuel tanks are always topped off.
Doing a little of the leg work upfront has always paid off in an enjoyable stress free day on the water.
