Can you use a car 305 engine in a boat?
Yes, you can use a 305 engine on some boats however, you need to provide more info on the type of boat. Putting the engine on an inboard/outboard, style boat would not be difficult at all, as long as you already have a good lower unit, same goes for an inboard. An outboard, on the other hand will be difficult, if its even possible to run a horizontal engine vertically.
