Are there any of the Minnkota's that work with remote (wheel) steering??? I didn't think there were.
The boat is a 14' wooden outboard runabout.
Here's my web site on the project: https://sites.google.com/site/danrobertstx/home/boat-building/mischief
Here's the site with the original plans: http://svensons.com/boat/?p=RunaboutsOutboard/playboy
Anyway, it's a small wooden boat that currently has a 30hp outboard. At 200 pounds, it really does weigh down the back end of the boat. Plenty of power, but a LOT of weight. At planing speed, the boat starts porpoising (bouncing up and down front to back). I'm getting ready to try adding trim tabs to see if that will calm the porpoising (which is currently limiting my top end speed), but I also had thoughts of converting the boat to electric.
Since the boat is WHEEL steered, the Torqeedo 4R would be good. And I'm curious if 10hp might be barely able to get the boat up on plane.
Even if it can't get up on plane, it would still be fun to just troll around in. I'm also starting to think about maybe building another boat from scratch that would be just a little smaller, and quite a bit lighter (since I wouldn't be building it for a 30HP engine).
If I had it all to do over again, the Torqeedo 2R would provide 6hp, plenty for just puttering around, and be easy to get going with 2 x 12V batteries.
The motor is pricey, but otherwise it's easy to set up and run, and no worries about gas, impellers, tuneups, etc....
If the 4R would get a small boat up on plane (they show that with RIB's, but not sure how practical that is with a 12' wooden boat...), then maybe it's worth just sticking with the 4R. The 4R is only about $500 more than the 2R, and has almost twice the power (at twice the battery headache).

I don't know how small your "small" boat is but why not try a 12 volt MinnKota? There would be only one battery and if you buy the PWM version of the MinnKota the battery will last longer. Thanks. Steve S.

The converter does not increase the power (watts) available, so to get 2000 watts at 48 volts you need 41.6 amps. To get the same 2000 watts at 24 volts you will need batteries capable of providing twice that, 83.3 amps!
