Straight Shaft Motorized Kayak

Sounds like a solid plan. I ended up using a steel fishing seat swivel to rotate the drive, works very well and has a low profile. Pictures of the motor base and coupling housing can be found here if you've not already seen them.

I had mounted my actuators inside the hull at one point. I used threaded rod and 2 pieces of aluminum angle to attach actuators to the motor base plate. And the other end of actuator was attached to coupling housing bolts. I preferred this setup, as the actuators are far more protected.

I used 1-1/2" aluminum pipe attached to the coupling housing with a pipe flange.
The 3/4" id cutlass bearing I used had a 1-1/4" od.

I tried to make as many features adjustable as I could and it definitely helped once I started testing the drive.

 

Hello again. Do you know of a way to convert ft lbs of thrust to ft lbs of torque?

 

I unfortunately do not have a clue.

 

I found out how and now I know why the trolling motor companies play hide the salami with their motor specs.
Using the conversion tables, my 86 lb thrust, 24 volt trolling motor comes in at just under .8 hp running at peak amps and watts.
I would have never bought it if I had known it was less than 1 hp.

 

Eletric motor is input power, not shaft power.

 

Hello again Irie....Just a few questions about your ME motor.
I got a new ME0909 4kw, 100 amps continuous, 300 amps for 30 seconds. It pegs a 200 amp ammeter under no load, at low RPMs. just a one inch shaft, 2 bearings and a prop. I don,t think anything is in a bind. I don't have a tachometer yet but I can tell you that the RPMs at 100 amps draw under no load are less than 1k.
How is your no load amp draw compared to your loaded amp draw? I haven't put it in the water yet because I don't want to ruin a new motor if something is wrong.

 

I should be able to get that info for you today. I don't know that I ever recorded that. What are you using for a controller?
