Using muffs

[boscoe99]

It is not abnormal at all for a Yamaha to over temp if being run on just flush muffs. Put the motor in the water and see what happens.

On the larger motors the muffs may not furnish enough water for the pump, so some use the hose flush and the muffs to make sure enough water flows or like Bosco said put it in the tank or lake/ sea at boat ramp to run

Thank you
