just so everyone that owns a 210/215 knows the is a channel at the transom that allows water to transfer over to the starboard side for draining.
also there has been a design change in the recent models and it is necessary to install the drain on the port side. Hopefully dick or another dealer will advise us which model year the change was made in
Called Carl at Merritt and recommend using 2 drains as he could not confirm channel to allow water to transfer from left to right side. Mentioned there is a beam that runs the length of the boat so didn't thin channel exist. 2001 210 cc
