How much throttle with muffs?

[LukeB777]

How much throttle can you give an outboard with muffs on? I have a problem that I need to check about halfway through the band. Thanks

How much do you use when revving your car in the driveway?

Not much.

There are things a mechanic could do to check it out of the water such as loading the motor with a strap on dynomometer, or test prop used in a big test tank.

But for you you will probably have to head to the lake or river for testing under load.

If you describe the problem you want to check out, perhaps you will get suggestions on how to do this without over-revving your motor on muffs.

It's possible for a 2 cycle to load up, then decide to burn it off all of a sudden if given a sudden open throttle and no load. While it's running away, rods can escape their designated path, pistons change holes, flywheels become frisbees, you get the idea.

Best to keep it below 2 k for sure.

hope it helps
