For a raw water washdown you could likely plumb it in with tubing and pvc pipe. It all depends on what the lift capability of the pump as to what type of pressure you'll get. Is it transom mounted?
Not enough space. It will have to be above deck. I'm not looking for much pressure as much as running water to use while fishing. Do you think these type of pumps can run with the hose shut and not burn?
Yes you can if you want to just dribble water on your deck.. If you had asked whether it will work or not, I would have said no. You will need a pressure pump for wash down purposes. I love my Rule 1100 for my bait system, but that's it.
