Noooohhhh

You don''t want to be doing that. The way to go is hybrid technology - probably Toyota or Honda. The powerplant would work well in Amphicar, about 80HP so useful on land but not uncontrollable. It is often split so petrol drives the front wheels and two electric motors drive the rear wheels. You change this so the petrol engine drives the rear wheels through the standard Amphicar land transmission but you drive the propellors from the electric motors.

Benefits:
Silent on water - how cools is that - can hear what people shout, hear the waves and the ducks...
Opens up more water, especially lakes, as Amphi becomes an Eco friendly electric boat.
If props are electric powered it is easy to control them individually. Amphicar becomes very manoeverable, can turn tight corners like normal boats.
Unlimited water range, as batteries get low you can charge them by turning on petrol engine - this uses less fuel anyway than standard Amphicar.
Hybridpetrol engines are super efficient and run cool.
The battery packs can be moved to get the weight distribution correct - you actually don't want to loose too much weight from the rear of Amphicar or it becomes nose-down and doesn't work well in water.
I'm seriously going to do this one day, probablynot for 5 years or so as by then my boys will be old enough to help - possibly as partof asenior school project.
