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?

Your build is one that I come to first when I get to the forum. WOW! That is one purdy engine! :D Thanks for sharing your work of art. We are all looking forward to seeing it launched!

The bottom of the aft face of the engine box will be hinged to the sole, so the box will swing up out of the way, giving servicing access as per the photo.

Yes, there will be access to the sump plug if the sump needs to be completely drained.

None that I'm aware off. I wish there were, as I'm very much having to feel my way. I can't even find similar hybrid drive train setups documented on the net. I can find plenty of concept discussions, but no actual builds. I've got no doubt they are out there though. Have you run across any actual builds on the net?

It was nice walking into the shed this morning and seeing it in the boat rather than on the ground. :D

Only full electrics. I'm looking to take a different approach to hybrid; all electric drive train with 1 cylinder diesel generator. That let's me use renewables for most charging but gives me range and backup when needed. Li-Po banks in the 30kw range and outfit with LED and leverage low power navionics (may make some of them).

That's the plan anyway.

Hmmm. Strange as it may seem, perhaps this is the first DIY diesel-electric hybrid build documented on the net. :o
