A new dressed power plant.

Remove the old and sell it for parts.

Install the new power plant.

Yamaha does not sell dressed power plants. Therefore you will have to buy an F250 cylinder block and heads. You will then have to buy all of the accessories that bolt onto the block and heads. Computer, electrical generation system, ignition system, fuel injection system, throttle body, wire harnesses, starter system, etc., etc.

There is a small chance that some piece parts removed from an F200 power plant might be usable on an F250 block and heads.

About US $25,000 or so should do it.

Let us know how it works out performance and fuel economy wise.
