> I don't know if it would be a very profitable business, but maybe break even ... It depends what you use it to smuggle :-)
Here is a link that suggests it is hard to beat an outboard engine if you need something suitable for predictable shallow water....
Like a car without a differential, I think a wide propeller would slightly resist turning. But more critical would be if one propeller creates...
A someone mentioned, an outboard drive powered by an inboard diesel and a hydraulic pump/motor may make sense for a boat that needs to run up on...
IMO, the best way to start designing a boat is to look at the existing ones that come closest to your specs. If you expect yours to go twice as...
I understand that outboard HP is measured at the prop and an inboard engine is measured before the gearbox. So at the prop shaft, an OB has the...
I'm curious how much efficiency one gains from using a 16" 900 rpm prop over something like a 11" 1800 rpm on a high-thrust Yamaha T9.9. 10%? It...
Probably the LR2 here: http://www.bluemoment.com/manuals/lister_man.pdf
I think that lanolin or grease mixed with waste oil would stick better.
I agree, people seem to get quite good efficiency and total hours from Honda inverter generators. Eventually we will see more people using...
A full, sealed can of beer is pretty strong.
I've suggested this too. It works well for inflatables. Fiberglass and aluminum compartments could have a plastic bladder inside to make them...
I would have guessed that if you know the forces will be say downward, then the bottom should be strong in tension and the top strong in...
You can Google "wire arc spray" or "thermal spray". It's been done on fiberglass and metal boats. My understanding is that with fiberglass, they...
But a metal arc spray machine and apply zinc/aluminum or perhaps some copper mix. It cools fast enough that it doesn't harm fiberglass.
