Thanks Jape, that's really helpful feedback. On that basis, I'll have some difficult questions for the distributor and likely won't be buying. A...
I see your punk rock and raise it to Metallica! You don't just hear the music at a Metallica concert, you feel it in your chest.
If you installed diesel OBs you could just run a little diesel jet heater. Those do a really good job heating boats, motorhomes etc.
I'm slowly making everything as identical as possible across boats. Engines, hydraulics, pumps, electronics, deck-gear ...
For me it's the survey hassles. Every survey the prop shafts and rudder have to come out. With outboards you just have to recondition the skin...
[1] Outboards tilt, so easy to address entanglement [2] You just fit a riser onto the top of the jet casing, that comes to above waterline...
Electric winches/rams would need to be AC. They'd be exposed to the elements. Too much risk. Almost all our deck gear is hydraulic, it just works
A few mussel farmers here have tried surface drives. They've all ditched them. Because of breakages and entanglements. Mussel farm structures...
I'm now no longer sure I understand what OP has planned :). If it's using the keel cavity as sort of open-topped reservoir to circulate cooling...
Sorry I missed your post. I don't know yet. My gut says we will need quad 200s or trip 300s. The naval architect is doing the numbers this...
To fragile and too much entanglement vulnerability around mussel farms.
I'm responsible for a small fleet of commercial vessels. We use keel cooling in 15 of them. 2 - 3 circuits per vessel. One per engine. It works...
There are couple of reputable companies building alloy cats in NZ. You could get a hull built and shipped to you? Blackdog Cats and Kingfisher...
They're electronic and can sense non-polar liquids. I was using float in the figurative sense. I should have been a bit clearer. Too late to...
I'm not across all that detail, but the bigger vessels hold about 5o0L in the total system, about half of which will be in a reservoir and heat...
