FAQ

Is this the correct first service kit for the F70?
Yes. This kit includes the core components commonly replaced during the 20 hour break-in service interval.

Why are three quarts of oil included?
The F70 engine requires approximately three quarts for a complete oil change, so the kit provides the correct quantity.

Why are two lower unit drain gaskets included?
Most lower units use gaskets at both the drain and vent screws, so replacing both helps maintain a proper seal.
