Stainless exhaust elbow. Heh. Famously poor idea.
Doesn’t a 1 cylinder diesel shake and vibrate something fierce?
For the price one might consider simply using the auxiliary engine — wear it out and replace sooner. Simpler, lighter, smaller, quieter, smoother.
It is truly regrettable that our auxiliary engines don’t have a better way to connect a PTO generator. A flywheel generator would be slick. Or simply a PTO shaft from the transmission.
wasn't it yanmar that brought out a cassette type generator to do just that, from memory it fitted between the bellhousing and gearbox/ sail drive, that was late 90's from memoryProbably. It is on rubber mounts. Don't know how big a problem that would be.
I mean, that was kind of what my other thread was about. Powering a generator from an auxiliary. But I think most people seemed to suggest that if I wanted power from the auxiliary I should take it off by way of a high output DC alternator, as you say below.
Some youtuber stuck magnets to his flywheel (on a lister clone or something like that). He wasn't trying to get any substantial power from it. But he lit up a few light-bulbs or something. It would be nice if the marine transmissions had PTO. Like tractors.
