 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

Hey everyoneMy name is Brett and I am in the process off converting a Downeaster 38 from diesel to electric. We use this boat in harbour tour service in Thunder Bay Ontario.
