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!

 

Anyway, I just wanted to let you know that we have forum topic under general discussions that we're using as an archive for previous messages to all members, concerning info about this site. Here's the topic:

Decision Tree for Electric Conversion

First, let me say Hi to all of you.  I am new to the group, but not to sailing (40 years and counting). I have blessed myself prior to turning the key on an Atomic 4  after refueling, torn my hands bloody bleeding a Westerbeke 4-60 (the block of which is from a British Taxi engine) and changed the timing belt on a Piranha engine(the British version of the VW Pathfinder with the added advantage of electrics by Lucas, the Prince of Darkness).Suffice it to say, I am open to electric propulsion.…See More

30' Pilothouse Motorsailer a good conversion candidate?

Today I looked at an old wood Sea Sailer 30 pilot house motor sailer to restore. I'm hoping this group can give me some input on the wisdom of going electric with something like this. Does the heavier engine demand due to less sailing ability make it a dumb idea? It's 13,100 lbs displacement, originally had a Perkins 40 hp and 100 gal fuel tank. It would leave plenty of room under the floor for a big battery bank, but would I end up dangerously short on ballast? Or might being lighter improve…See More

Use of the load feature on Morningstar Controller

Just a quick question about using the load feature on my controller. I have a 32" Freedom powered by a 48 volt motor. Eight AGM's wired to provide one large 200 amp 48 volt battery. System works fine. I also have a small West Marine 12 volt, 32 amp battery not hooked to the system. Can I wire this battery directly to the load on my controller to charge it? Any precautions I should be aware of? Thanks, Jim

2v Battery Bank and charging

I got tired of going out to the slip and trying to crank over the old 2 cylinder Farryman on my 1972 33' Pearson.  I got more splinters from the dock than sailing time.So, I've decided to go electric.  I did some research on the different companies and settled on a Thunderstruck 10kw solution.  The owners there answered a lot of my questions every time I called them and never seemed bothered when I called.Check - motor selected.Next item - batteries. I had initially decided to get 4 Lifeline…See More

Parallel plus Series I'm confused

I need some help. I believe I have the right setup but before I blow my controller I would like a second opinion or three.  I have four 12v and a controller and electric motor both at 24v. I believe the setup pictured below will work but need some corroboration please. Thank you in advance.HarrySee More
