Franklin Airboat

[Bgaugh298]

I run a Franklin airboat, the motor runs good and strong. I also have good connections for parts.

But for some reason the motor is running hot and it keeps sticking valves and bending pushrods.

Any advice to get it to run cooler

Just about every Franklin I've seen and had one ran a cooling shroud, we also ran Marvel mystery oil as a top oil in the 100LL fuel.

What’s the purpose for running the mystery oil? Just extra lubricant?

Yep, can run 2 stroke oil or transmission fluid as well.
