Compelling reason to restore my antique diesel

 Ok, before I'm kicked out of the forum, look at this Utube.http://www.youtube.com/watch?v=21rJ30Y-sZg I don't have the same engine but my diesel is an old lifeboat type engine that has a similar characteristic. Another hobby I enjoy is playing music and this could be very handy. Any ideas on how I could get this out of an electric motor? WalterSee More

electric motor selection

Greetings all,Maybe I didn't search the right places but got no information when I did.I've decided to go electric. My boat is a 1971 Nantucket Clipper, 7.5 ton yawl. She has a 3/4 full keel cutaway aft.I would like to find the best motor to fit my ideal auxilary power source. As a sailor I want something that will go when it's needed. Dependability. My sails will always be the primary but I just ran aground on my friends boat and the removal process involved his powerful diesel in reverse and…See More

Hi Walter, so what kind of sailboat are you rebuilding? I restored/ renewed my 1967 Bristol 32 with an electric propulsion system and I can say it was the best thing I ever did. Please tell us about your project!

Lithium battery pack needed

Update on Lilliput.Last year was a long struggle to get out the old engine and all it's associated pieces. The steel frame bolted to molded in stringers was the worst! Had to cut it out with tiny grinder wheels. It was glassed in to the compartment wall at the rear end with only an inch to spare between the sides of the hull and the steel. It's done!!! I've installed Joe Steinberger's electric motor setup and am looking to buy…See More

AGM Battery Anomaly

Just when I thought I was ready to splash my boat for the season I made a disturbing discovery concerning one of the batteries in the 48 volt propulsion bank. The Dual Pro PS4 battery charger showed battery number four with a blinking green light where as all the others were steady after having been charged.  This was a new development as for the past several weeks all the batteries had been charging normally on my visits. For some reason the charger thinks…See More

Another newby with a Dream

Hey guys! Looking for comments, ideas, examples, intellectual smackdowns (i.e. "What the hell were you thinking?), etc.I came over here from CF because I got tired of the narrow-minded "can't do" attitudes over there. Even when you give them examples and videos, they still refuse to admit that it CAN be done. Well, I'm 20 years retired military, so I have a WILL do attitude and I am the epitome of hard headed. I usually get it done. I'm currently tossing around the idea of an…See More
