Just the modification I have been thinking about. Let us know how it comes, & take some pictures. Tom Woodworth M-17 "Wild Hare".

I chose this area to install because the cockpit floor dips to center rear of cockpit right at this area. I will then install another 1 1/2" through hull at transom (above waterline) but below cockpit floor so water will drain. A hose connects these 2 through hulls and a one way Whaler check valve is installed inline between through hulls (to prevent seawater from entering cockpit). This method is similar to new M17's except they have 2 drains/through hulls, one at each end of rear cockpit area; also mounted horizontally, also utilizing one way check valves. I believe this upgrade idea will greatly increase the volume and rate of which water is removed from cockpit. It also removes a through hull that is below water line (original drain).
