Thanks for the kind words and wit Tom, Fuzz, topwater. and cape man.

With the position of the Aquadrive settled, this afternoon I made minor adjustments to the positioning of the electric motor and the batter banks.

Then I cut and dry fitted a template for the platform the motor will be mounted on, which itself will be mounted on soft engine mounts to reduce motor vibration being transmitted to the hull, and to enable belt tension adjustment.

Spent the last couple of days interstate at an oyster restoration conference. While flying back home an idea flashed into my dozing brain on how to improve the forced air cooling for the electric motor. Only trouble is that I've got to abandon the work done on the current mounting position. :roll: But it will be worth it. :D

Did you have a systems layout anywhere? I'm curious to see the evolution as better options presented themselves.

I'm not that sophisticated. I'm just muddling through!

It's only recently that I've understood the specific air cooling challenge for this installation. Normally this electric motor would run at around 3000 rpm, with its own built-in cooling fan doing an adequate job. But because for this application the motor is being programmed to run at about 1000 rpm maximum, with full torque (and hence heat generation) being achieved by then, the motor's slowly rotating fan will need assistance by having cool air force feed into it by another fan.

Enjoyable afternoon's work starting the diesel engine installation. :D

In an attempt to fend of Murphy, I'm going to test fit all of the diesel drive train subsystem and all the electric drive train subsystem, then check the integrated system, before permanently installing anything.

Looks real good sitting there :!: And it looks like there is room to work on things when the time comes. That is a big one to me.

Do you have service access to oil sump?
Probably you will put a pump for oil but it would be good to have access to sump plug..

Chicken ;)

I think you mentioned this before, but are there other hybrids like this on the waters where you are? Similar drivetrain setups?
