Converting a boat to electricity

The toughest decision is whether to retain the wet exhaust(requires keeping a water intake and pump which may block with weed) or fit a dry exhaust; there are pros and cons for each.

Indeed, it's my back-up plan if electricity proves unfeasible - which it probably will, but I like to investigate all angles. The simplest answer is to move the water intake from underneath the boat to somewhere it can be reached in an emergency, eg near the transom/bathing platform. But I'm not sure if the turbulence there would affect operation.
