When you buy our complete packages. You only need to bolt on a gearbox and prop. Bolt on your motor mounts. Mount and wire the engine. Plum the fuel lines from your lift pump to the high pressure pump we provide. Then from there to the fuel rail of the motor. Run cooling lines to your radiator and burp tank. Fill it with a 50/50 mix of Dex-cool and water. Hook up guages and intall an intake large enough for the motor. We provide everything else. We will also bolt up your gearbox for free if you bring or ship it to us.
We also have intake kit for sale that fits on some boats and has a filter large enough K&N filter for the motor. Just ask about it when you call.
