Yes you can. On newer boats there is a baffle that stifles some of the water flow. Regardless, after you unscrew and pull the transducer, put the replacement plug in and and tighten it. You will get water, but your bilge pump will handle it.You can clean the speed transducer while the boat is in the water from the top access point? Thanks for the help.
about that... I better have someone on deck pumping... or a nice size bucket next to me. I was surprised to find no electric bilge pump in the bilge of my boat. As in there was never one installed, and no real means to install one without tons of work. We have a basic manual bilge, but the hose run is at least 15 feet. No electrical within 5 feet of the bilge. I would have to cut a hole in the boat for a pump out... Stupid. I need to do so much work on my boat =) This thread is for a later day. Thanks.your bilge pump will handle it.
