I have a 1991 gls175 sportfisher sea nymph, wanted to buy a rip tide trolling motor not sure what size would be enough. Also what shaft length ? Was thinking about possibly 70lb thrust power drive v2.

If you use it alot get the biggest you can,...

If you have room for three batteries get the 36v 101,....

If not then get the most pound thrust in a 24v system you can,...

Also, get the longest shaft you can,.....Nothing more annoying than the trolling motor coming out of the water in some chop,...

I've never heard anyone say they wish they had bought a smaller trolling motor,......

You don't need a 36 volt motor -- because you probably don't have room for three more batteries.
You don't need a 36 volt motor -- because it is simply overkill -- both on power and your wallet.
A 70#, 24 volt model will be just fine on that boat. It requires two batteriess in series.
You float the boat and measure from the surface where you mount the troller to the water and add one foot. Pick that shaft length. Once installed the motor can still be adjusted up or down by turning a knob. But you need the motor at least one foot in the water.
The Minnkota web sit will tell you all you need to know.

I had a 50lb thrust on my 18' aluminum and it worked great, typically trolled at about 3 on a 5 speed motor then up to 4 as the battery wore down then used 5 for the last hour.Could get about 4+ hours of continuous with a single group 27 deep cycle. If you plan on trolling against the wind then you will need more power. I normally trolled with the wind or at an angle so it used less battery. I had planned on running two batteries to prolong the run time but ended up selling the boat and bought a bigger one.
