FINALLY we had a dry day to launch and I got to try my new Torqeedo. It does not fit well. They are designed with a tender in mind, intended for a transom hung position, not a motor mount position. By being on a motor mount the mechanism of the mount interferes with tilting while the battery and tiller are in place. The tiller is too long when in the run position. My fix was to move the motor out on an additional rigid mount.

I have no idea why these shots are rotated on this site.

Hi Frank,
I had extended my outboard bracket previously to work with the 8hp Mercury that preceded the Torqeedo. The Cruise 2.0 is a bit less bulky than what you have... but still needed the extension.

My tiller on my new engine is too long but I just fold it up. It works well straight up.. I've gotta remember to add a rubber cover that will be easily replaceable to the end as it rubs sometimes if it falls down forward.

I sailed next to a 25 foot cal last weekend that was using a bass boat trolling motor.. pretty funny.

That torpedo looks great!

What is the horsepower equivalent of a 55 lb thrust electric trolling motor?

Thrust is the output of the motor on the propeller.
The horsepower of the engine is just the engine alone. Read the wattage of the trolling motor - something like 600 Watts (50Amps @ 12V)?
Then just calculate that 1HP is ~750W, so it could be something like 0.8HP :-)

Regarding the gas outboard to lbs conversion = 55 lbs / 600W = 0.0917 lbs/watt (of the trolling motor) * 5900W (for 8HP) = 540 lbs.

Except that gas and electric motors have some different characteristics. Electric motors develop max torque at zero rpm, so prop size has a serious impact. More torque is delivered to a larger prop at lower rpm. It is very difficult to compare the two directly unless you have measured thrust values for both.
