Yamaha 140Hp Overheating

Rapson does the MACS product foam up a bit?? Thats the big disadvatage with Salt Away. Foams all over the place like dish soap.

Hey Tucker, the MACS dosent foam up and is more like an oil that dosent mix with the water.

Talked to a Yamaha man today as I had to order brush set for the Trim Tilt motor.
I told him what was going on and what we have tried so far.
He came back with "It could be not delivering enough oil at high RPM, this would bring up an alarm". He did say the gauge on the dash should tell me. But I have never paid much attention to the gauge's. And now the one that would tell me is AWOL. So have to replace that.
