Just put a length of half inch PVC under the cover and bent between the rails over the middle of the engine box. Hope this will allow rain to drain off. We are expecting rain tonight, I will see in the morning if this works.
Cover support
PVC in the cockpit works great. No water accumulation. Found that you also need a support at the bow, as the high rail creates a great place for the water to pool. Ran a half inch PVC from cabin top to center of bow rail. Boat cover drains well now. I'm happy.
