I am considering a scratch built amphibious 4x4 EV with the following minimum requirements:

-300 lbs cargo plus two people
-road-worthy (ie can get it through Connecticut DMV inspection)
-land range 40 miles at top speed 50mph
-water speed a few knots
-climb up a sandy beach
-salt water operation in calm waters

My thoughts are to build a fiberglass hull with in-wheel submersible hub motors attached to the hull with 4x4 coil suspension from a donor 4x4 vehicle.

If I can't find suitable motors (which is why I'm posting this) then I guess plan B would be to modify a 4x4 EV truck kit to be salt-water proof and integrate with the hull.

Heard of anyone that has done something like this?

Any other ways to approach this?

(yes, we do have a boat)

Consider converting an Alvis Stalwart amphibious high mobility machine over to electric. There's one for sale in CA. It'll get through the state inspection.

Ha! That would be one heck of an EV project. What a beast!

The "getting out by the hatch in case of rising cabin water" part would be a hard sell to my wife.
