Running an I/O on "earmuffs"

acg123 · 08-19-2016, 05:21 PM

I was surprised to see people say yes. I have read in multiple factory manuals that you should never put the motor in gear when it's out of the water, even if it's connect to muffs. There is absolutely no resistance on the prop, so it's going to spin very fast, and when you take it in/out of gear, it can do damage to the prop hub, as well as other parts. If you really need to spin the prop, back it down a ramp, or lower the drive in a tub of water.
