I have a
2" Harbor Freight pump with aftermarket bi-fuel carb; have tested it 4 times in fresh
water using
propane only (carb hasn't seen gasoline). Have a ?15ft extension hose to run off 20# tank or can use 1# bottle; with
propane I'm less concerned about gasoline gumming things up. Currently pickled in a bag in the lazarette waiting for an on-deck box solution. Rated for 9,000 gph could be used as a firefighting handline...it moves
water. I probably have $300-350 into the whole kit.
I've got a pilothouse with large ports/windows and otherwise wouldn't have purchased it if not going
offshore. It's relatively small and lightweight but the
steel tube frame is thin/biodegradable. If I ever use it in
salt water I'll certainly take the
pump apart soon after inspect/clean.
