Just bought a 1988 skeeter starfire bass boat but wont be able to pick it up till next week, but it needs a trolling motor and I would like to get one before I pick it up so it would be ready to install. I was wanting to know does anyone know or know where I can find out what size shaft I need on a trolling motor for this boat.

The 10 inch in the water is the spec. but if you fish big water I would add. a 42 inch model 24 volts should be top shelf.

Many bass boats come from the factory with a 42" shaft trolling motor.  If you plan to fish windy water then I suggest a 45".

Well, you can't hurt yourself to go long. Most boats come 42.

Get the longest shaft and most power you can afford; you will not be sorry  

The motors with a continuously variable throttle (digital speed control/maximizer) will double your battery time when operating at 1/2 power or less. Thats where I spend most of my time. Not cheap, but neither is an extra battery set.
