Shaft Length


how long is the shaft in inches

What length of shaft do I need?

First, that depends on whether you want a transom mounted motor or a bow mounted motor. If you go with a transom mounted motor then you need to know the distance from the transom to the waterline when your boat is loaded. You want to take that distance and add at least 20 inches to it. If there isn't a shaft in that size then round up. Let's say the distance is from the transom to the waterline is 10 inches. You then add 20 inches to that and the length of shaft you want is 30 inches.

If you want a bow mounted motor then you take the length from the top of the bow (where the motor would be mounted) to the waterline when the boat is loaded. You then add 20 inches to that number and then round up to the next longest shaft if you have to. So, if the distance from the bow to the water is 15 inches then you will add 20 inches to that. You come up with 35 inches but find that there is no motor for the brand you want with a 35 inch shaft. Therefore, all you have to do is round up to the 36 inch shaft. Simple, right?
