I wanted to keep my splash well in (mostly for the small kids we haul sometimes), but could not wash the aft deck easily. I added hinged scuppers to each side of the splash well on the bottom. They work much better than the small Parker slot on each side for washing. I washed the deck after this photo & the size of the scupper I installed works fine.
Now that I look back at the project, I wish I had removed all the screws in the deck and only left the screws holding the the starboard & port ends. Might even have slotted the side holes to raise the splash well for washing. Might have slotted the ends too so that the splash well might be easily lifted out without fooling with any screws. Guess I could still do that one day................................Pete
