everyone..... just breath here.
New member, possibly new to forums and obviously new to boats or at least misters and might be a 22 year old kid. Who knows?
I made the mistake of asking about a bayliner on my first post on my first forum - The Hull Truth which if you have been on there any length of time you know to be brutal to folks like me.
To the OP - the first thing in any troubleshooting of anything no matter what it is - start at the end point of the problem then work your way backwards. You know this is a mister, something pumps water thru a tube. Work backwards (or start with fuse panel)
