I have a 16ft. Boston Whaler Dautless and would like to know what length trolling motor to buy. I have contacted Minn Kota and they recommended to measure from the bow to the top of the water and add 20 inches. Does that sound right? Any suggestions!!

I have a 48" Riptide mounted on my 160 Dauntless with a 4s 115 on the other end.

Works great in calm to moderate water. If you're thinking of using the trolling motor in chop I would suggest a 55" or longer...

I just mounted a 48" minkota 12V 55AP (autopilot, 55lb thrust). Works great.

On my Dauntless 15, the distance from the bow to the waterline is about 24". Minnkota recommends that you have the motor in the water 12" more if it is choppy. Witht the 48" I get two feet down into the water and have not ever had a problem with chop - and we get some major boat wakes. I think the 55" would have been far too long.

The 55lb thrust is plenty adequate for my D15 with 2 kids fishing with me. Most of the time, I have it set at 2-3 (out of 10) for fishing. If I kick it up to ten, you could practically waterski behind it. ;-)

I don't remember what Minnkota recommended but it comes out to something like 2 lbs of thrust for every 100lb of boat weight. Using 2000lb for my boat loaded says 40lb but then more is better and i wanted the autopilot.

I mounted a connector in the port side of the console with a 45 Amp breaker that can be used as a switch. Then i made a cable out of 6 gauge wire that connected to the motor and runs back to this connector. The heavy cables lay very nicely on deck and are not a problem. I wrap the cables once around the handholds of the console to strain relieve the plug then connect it. Connector is the Marinco panel mount twist lock connector specifically for trolling motors.

i would guess the same setup would work well for you just make sure of the height above the waterline. Too long is just as big a pain in the hinder as too short.

The 48" Riptide on my 160 Dauntless all the way down on the mount gives me about a foot under water.

A longer shaft, 7" in the case of 48" vs 55", is no problem as you can just move it up on the mount to the depth you need.

The design of Johns 15 and the 160 Dauntless may be the reason for the difference or perhaps it's the weight of our engines.

Like I said earlier a 48" will do the trick in most cases. :)

I think the D16 has a higher bow than the D15. 6-7" i wouldn't sweat. 12" and i would drop down a size.
