Then if you compare the fuel consumption for that same diesel, you can see why diesel electric is an interesting proposition. At anything other...
I agree it presents no real advantage in marine use, I`m just highlighting fundamental engine differences. The flat 100% rated torque curve is a...
When it stops turning. Electric motors and steam engines don`t do that, well power goes to zero but torque doesn't.
Google speed torque curve. Since we are in the 21st century its not like no one has ever measured the performance of an electric machine on a dyno.
There seems to be some miss understandings in this thread. Electric motor rating plates show two things, the HP rating, this is shaft output,...
I had purchased an old fisherman 5.5 evinrude for my little boat project that had two major issues. One I could never get it running right with...
Correct. Zero flotation and very rock like performance underwater. So while it "feels" more sea worthy than I expected, it is certainly not a...
It is pretty quiet, I have to find a rattle in there, I think the rivets holding the recoil starter have loosened. By ticking I mean ticking...
update So finally got it painted, floor in and went out for its maiden journey. The evinrude two stroke, environmental disaster on water that it...
I'll throw in my 2c, I would go with a wirefeeder no question. Even my little 110V lincoln on max voltage with flux core will easily weld 1/8th...
HMCS Tincan floats! Dragged it out of the basement and threw it in the water to see how it goes. Must admit, pretty cool to finally not only...
Unless you have the 1/8th steel already I think you'll find that a bit heavy. 1/8th is ~5lb/ft2. But if weight doesn't matter just factor the hull...
Oh I know stainless is steel, Aluminium is not ;)
Don't know if stainless steel would be any good. Technically not "steel", but you can use unpainted aluminium...
thats cool! :)
Yes ideally he should ask someone who knows, and someone that can estimate based on the design he has in mind. However, if that information is...
I have no experience wrt cost of welding a boat, I would go and see if you can talk to a yard with a sketch or drawing in hand. I agree that a...
Re running starter motor "backwards", sometimes brushed machines have commutation advance built into the brush holder so you might find it does...
Interesting is the statement on thermal efficiency, 35% for 4stroke, 50% for teh two stroke. Re scavenging, 2 stroke diesels can not be...
Yeah the first thought was to just wrap the tube around the boat and weld, but once I got the tubes they turned out actually surprisingly stiff...
