What a terrific idea. may I ask what pump did you choose? I do have an oldish Jabsco fresh water pressure pump that does have some powerful suction in to. Not sure how good it is at sucking up small quantities though.
Jabsco Water Puppy with a strainer. 5/8" or 3/4" hose. Make the hose long so you can cut the end off after sucking out the clogged head before sucking out the fridge ....
One, I removed everything, and then some, that I didn't absolutely need. Never need to repair or move or clean any of those items ever again.
Second, installed a small suction pump with a long hose that reaches every locker on the boat. Invaluable for keeping everything dry, cleaning the fridge, trapped seawater puddles after a rough passage, even sucking up spilled coffee off the stove top.
Agree - an excellent idea. Where does the pump discharge? Regarding your first point, I'm doing the same thing this year. It's amazing the amount of stuff I've hauled around for years that I might need "some day". Doing the same at the house as well.
I ran a length of cord from the decompression lever of my Yanmar1gm10 to the cockpit locker with a loop at the end.The engine starts much easier now.
Pull the cord,press the starter button, release the cord and it's running.
