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

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!

Newish Solidnav user seeking a bit of solar help

Our Cal 2-27 came equipped with a Solidnav drive from the previous owner. Over the few months we have owned the boat I've come to really love the drive. Where I'm running into an issue is with figuring out a solar set up. I may own an all electric boat, but I am far from electric savvy.Yesterday I spoke with BlueSky about an MPPT and it wasn't a productive discussion. Our battery bank is built around four AGM batts. While I understand the drive requires 48v, what decisions does this force as…See More

Thoosa 6000 throttle

Hi Everyone!I'm brand new here at ES, nice to meetcha :)I need to replace the throttle "handle" for my Newport 30. I'm running a Thoosa 6000 and I'm guessing, by looking at the manual, that I need the dial kind.I'm at the Alameda Marina in the SF Bay area Ca. so I think a Thoosa dealer shouldn't be too hard to find. I hope!Thanks very much and I look fwd to electric sailing!Laurie Miller ⚓See More
