At least as described, this is not a well concieved idea and is a far more major a modification than has been suggested. To begin with the website says Mars Brushless motor is a suitable substitute for a 3-12 hp diesel. An Atomic 4 is a 25 hp engine that generally requires an 18 to 24 hp diesel as a replacement.
But even if the Mars Brushless motor offered suitable power. the project is huge, far beyond what is suggested on the Mars Site. As I think of the step by step process below, it makes an Atomic 4 rebuild sound like a real bargain;

8D AGM's weigh 167 lbs each.
the atomic-4 weighs 310 lbs. dry. (add 10 lbs approx. for 5 qts oil)

Umm... How many batteries do you have installed? You're gonna need a lot of batteries for that to do much of anything. The batteries will probably weigh a lot more than your old A-4 did, and won't run quite as well or long IMHO.
Basically, you'll be adding weight, and making the system less versatile, lower duration of run time and more vulnerable to problems... Umm... what exactly is the upside to doing this...and it's going to cost you a fair number of boat units to do this.

It doesn't look too difficult,yank the A_4,run some wires and fab up a mount.
4 maybe 5 days,depending on beer.

|RickBowman||It's very interseting indeed. As it would be a major modification to your vessel, are you up for it? Of course so is any repowering. Thanks for sharing your idea.|

the search goes on
I was thinking about the re-e-power unit but the short warranty and the whole underwater motor thing turned me off.Please keep in mind that this
is going to be used for bay sailing and getting to and from the dock not "punching through" giant waves or clawing off homicidal lee shores.
Anyone have any experiance with these Electric Boat Sailboat Kit Mars Brusless motor Sevcon PMAC millipak regen controller
