Bingo...but here's how I've seen bad things happen.
You are making water in the anchorage, ever one is happy, drinks flowing and live is wounderfull when all of a sudden all hell breaks loose. The boat infront of you starts dragging and is heading right for you. In the panic you don't turn the water maker off and switch a Y-valve, you just start the engine
and alert the crew to make ready to bouy the anchor
and get the hell out of the way before your vessel takes a hit.
In the chaos you don't realize that for the last 20 minutes you have been running your main engine
with no cooling
water because you put a Y-valve on your main engine...it's over headed and in the chaos of yelling and screaming you failed to notice.
Ok...sound far fetched?
Well the exact thing happened to me TWICE while anchored in La Paz
, except I didn't share a through hull
and would NEVER share a through hull with my main engine or generator
. Not because I don't want the head
ache...but because I don't trust myself or others to remember to turn the Y-valve back to the device that will burn up without water cooling
Sharing a wash down or head
inlet with a Y-valve..sure...what can you really damage by having a faulty memory...but never would I recommend a water cooling device that can be damaged.
Because I've seen and have been part of these disasters...I preach against setting up the situation for one to happen.
