Having problem with getting the Pump to activate to fill sink . Manual states that need to activate switch at sink . Can't locate one .Any ideas

I can't speak for your model, but on my boat there is a switch at the helm to activate the water system. You also may want to specify what year your 245 is
so someone with the same boat can better help you out

My '97 uses the "ACC" switch on the dash to activate the pump.

The owners manual is not that accurate, on the old Four Winns website they had one that was from a few years before '97 and then one from '98. Neither were completely accurate.

My boat is 1998 245 Sundowner

My Sundowner 255 has a switch behind the skippers chair on the side of the sink mounting close to the gunwhale if that helps.
