water pressure using muffs

[MKI212]

My house water pressure is 80psi. Is it ok to use muffs on my Yama outboard with this high of pressure. Wasn't sure if I could possibly get water in the lower unit due to high pressure. Thanks for the help.

Re: water pressure using muffs

Don't open the spigot up all the way. You only need enough to get a steady stream out of the pee hole. At 80lbs the muffs wouldn't stay on.
