Re: Trolling Motor Shaft Size?
As with many things, going bigger is usually ok. Ever heard the phrase "I cut it off twice and it's still too short?" Trolling motors are adjustable for height. But they are not adjustable if the shaft is too short. If you buy the 54 and it's way too long, remove the head and cut the shaft off. You obviously have to buy a new shaft if a 48 is too short. But since we have no idea whether you have a Grumman canoe, a Grumman row boat, or whether you are talking about a bow mount or stern mount motor, we can't begin to suggest what you need. In operation, the motor must sit at least 12-14 inches below the surface of the water wherever it is mounted.
