Is there such a thing as too long of a shaft?? Right now, I have a motorguide with a shaft length of around 39". I am measuring from just below the head down to the top of the housing that contains the motor. I found a used trolling motor that has a shaft length of 52". If I measured my trolling shaft correctly, then there is a difference of 13" more. Are there any problems that I might have with a longer shaft?

Follow-up. If I wasn't clear before, I am thinking of buying the used trolling motor with the longer 52" shaft. My current trolling motor has a 39" shaft (I think).

Re: Shaft length for trolling motor

BassCat73,<br /><br /> To answer your question, Yes you can get a shaft that is too long for your application/boat.<br /><br /> I think that you probably have a motor with a shaft length of 42" instead of 39", (they measure the part of the shaft that is inside the head and the part that is inside the sealed motor,) and if that is the case try this; set your old trolling motor at least 10" higher on the bow and drop it over the front of the boat. Even though your motor probably wont be in the water, you will get an idea of how high the new head would be.<br /><br /> I am taking it for granted that you have a bow (front) mount motor, if not then you can do the same for a transom (rear) mount motor. just set it at least 10" higher than you normally run it and if you can live with the head in your way then I say go for it, if its a good enough deal.<br /><br /> One other option would be to buy the 52" shaft and have it shortened. This can be somewhat costly and it will negate ANY warranty that may still be in force on the newer motor. If you are pretty handy with tools and fabrication and electical applications then it may be something that you can do yourself.<br /><br /> I hope that some of this has helped instead of clouded the water...

Re: Shaft length for trolling motor

Thanks BlackKnight. I just found out that my boat is only rated for a 45" shaft, so I think I'll keep looking for something more appropriate. I fish a lot of shallow water, so I think I might have troubles if my shaft is too long.
