I have the same boat and never seem to get much water underdeck and surface water seems to run on top to the bilge ok when in motion. Why do you want to divert under deck instead of just letting it run on the top to the bilge?
Previous owner had trunks fitted through the transom that would clear any serious on deck water. So that might be another option. Depends on what your concerns are.
Iíve removed the rear jockeys and replaced them with a rear bench. The bench fits snuggly against the uprights by the side of the transom so there is very little room either side of the bench to drain water off the deck into the bilge.
Also when I took the deck up to remove the tank Iíve found that where the tank sat was a closed cell. No drain pipe through to the bilge. Looks like it was closed off with resin and mastic.
Iíve placed in two new drain plugs so that any new water that gets under the deck will now drain into the bilge, but Iíve still got to work out how to get surface water off the deck. As the space was really big, Iíve also glasses in a new stringer as well.
So I think the best way is to place in the deck two scuppers that join into a pipe under the deck and then empty out into he bilge area.
Hope that makes sense. Itís not about clearing water under the deck so much, more about clearing surface water off the deck.
