gotta get dirty
Hi,To the best of my knowledge, there is only one way to really clean the bilge.You need to add detergent (I use a West Marine enviromentally approved cleaner), water, mix it well, and then SCRUB the bilge with a brush, scubby pad, sponge, etc.After you have done that, rinse well with lots of water. Then get the bilge totally dry. Use the pump to get most of the water out, then use a hand pump, or something else, and finally use a sponge to get all the water out. Leave the bilge open to air out. When it is dry it will be clean.Keeping it clean is another story.... My old boat had a dripless shaft and dekc stepped mast and the bilge stayed dry (except after a big rain). My new boat has an old fashioned shaft log that drips and I can't keep the bilge dry. It also has a keel stepped mast so I get rain water in (coming in through the mast). It's been my experience that just adding water and detergent, then pumping it out will not do a thorough job of cleaning the bilge.Last comment - make sure you check under the engine to make sure you don't have a nice pool of oily greasy liquid in there. I learned the hard way that under the engine was a sort of small pool. Leaking oil, etc. would collect there. When I got the boat that pool was filled with oily water that would slosh out when the boat heeled. I cleaned it well and put a bilge pad in to collect anything that spilled. Twice a year I would clean that out and that kept the bilge clean.Good luck,Barry
