Howdy Folks. Looking for some assistance.
I have a Honda Model: BF90DK0 LRTA S/N: BBCJ-1016365.
Haved ran it in a couple of years and decided to fire it up today to see how she ran in anticipation of taking it out for the first time in about two years. Fired her up on the hose and everything ran great!

While looking at the lower unit I noticed water coming out from a few different locations. Cant recall if this is correct or not. See picture attached. Is this thing Cooling functioning correctly? Old age sucks!

Red arrows indicate where water was coming from.
It was pissing out the hole in the back top of the motor too which I know is the right place.
Thanks!

Generally speaking it is normal for water to come out various holes on the lower unit when running it on muffs, so most likely you're fine. BUT, it is not a good idea to leave the muffs on there without the hose attached. Many times people have forgotten those and launched the boat with the muffs on. The motor will run fine through the idle zones, then promptly overheat once you get on the gas. Also after 2 years of sitting, it's not a bad idea to consider a new water pump impeller.
