Water Pump Freezing Question

[trekkertype]

Hello, I have a 2016 Yamaha 150.......With modern outboards is freezing water causing damage an issue anymore. Obviously not starting motor when it is frozen, but generally starting the motor on a mild day when it was not previously drained. Thanks.

Welcome aboard

Outboards are self draining assuming you store them trimmed all the way down

Correct, and because of that, as long as there is water you can run them below freezing. I do it all of the time, fishing it rivers that still have running water in the middle of winter.

If you ever have your boat in the water at below freezing temperatures, always leave the motor trimmed down so that the pump is in the unfrozen water. If you trim it out so that the pump is in the freezing air, you will have freezing problems!

Wow - didn't realize how old this post was.....sorry!
