Re: Electric Boating

Agree, nice looking motor, boat and don't forget the Santa cap 8-)
Unfortunately around here, our boating season is over, pretty much all lakes have a thin coating of ice, probably 4 months before we can start thinking about boating :(

That's pretty much it: the bow will ride higher/lower when the motor is trimmed out/in, respectively. Trimmed 'out' means tipped up more (bottom away from the boat, towards the right in the earlier picture). You would typically trim the motor out to try to get more of the hull out of the water at speed (for reduced drag), then if it started to bounce up and down ('porpoising'), or just going slower, you'd want to trim it back in a bit. Trimming in can also be a response to rough water, softening the ride due to more of the hull in contact with the water.

There were likely more subtle effects in this case, like slightly lowering the propeller axis, and bringing the propeller slightly forward, thus closer to the structure under the middle rear of the deck that simulates what would be the hull on a monohull boat (providing a more stable water surface to the propeller).

EDIT: I see you were asking about vertical height changes, in addition to trim angle. You usually want as little of the motor in the water as you can get away with (to reduce drag). There is the effect you describe as well, and porpoising can result from the motor being mounted too low. But the more common problem is 'ventilation', which will occur due to the motor being mounted too high, allowing air to get sucked into the propeller. This issue is frequently and erroneously referred to as 'cavitation', but that's a different phenomenon, but with similar symptoms (propeller losing grip with the water).

Re: Electric Boating

Most above-the-deck parts have been removed, in preparation for installing better front seats, and probably moving the old front seats to the rear (doubling the seating capacity).

Re: Electric Boating

New front seats and motor controller installed.
Image
I wanted a storage bin under the pilot seat too, but the vertical helm supports don't leave space to get your feet through when entering/exiting. I have a plan to eliminate those supports, but not right away.
Image
The passenger seat swivels, and both seats fold down and lock when folded. The storage bin is lockable via padlock.

Re: Electric Boating

I took this yesterday evening after installing the rear seats (which are just the front seats I replaced).
