My 22 outrage has the plastic dome mounted in the bottom of the rear splash well with a round ball float in it. It seems like it should stop water from entering the rear live well at rest but the well [below deck] fills and then empties on plane. If I were to plug the live well connection to the splash well it could then fill with rainwater. Any experience with this. This is my third whaler but first 22. Thanks.
Your scuppers have a ball and a gasket to which that ball seals. Both are prone to contamination from marine growth and gas/oil which compromise the seal. I've had some folks tell me they have had decent luck just cleaning them with mild soap and something soft like a sponge but generally replacement may heal your ills. Even in new condition, I've not heard the best performance from such a system when they are below the waterline. They always seem to leak some and matter of fact I believe are intended for drains that are above the water line and just need splash protection or perhaps when backing the vessel down. Rabud is one manufacturer I know off that makes them.
My Outrage's splash well drains are open to the water. The splash well fills when off plane and empties when on plane. Been that way for years without issue.
Thanks, I have discovered the part is called a check valve. It connects the rear splash well to a below decks fish/bait well. I know it it standard Whaler as a friend had this same boat years ago. I guess the fit between the round float and the brass tube is not that good. I have been looking for a parts supplier on line to no avail.
Ours had the same thing from the previous owner, but it was on the outside of the rear drain not inside like yours. Took it off to check it out and it was hiding the fact that the rear thru hull was rotted out. So I kept it off as it looked pretty suspect anyway. Added a bilge pump to the rear fish well, directly wired to one battery (on all the time), and I keep the thru hull between the splashwell and fishwell open so any water in the splashwell is removed by the pump. The rear drain has a plug in it, reachable from inside the splashwell if needed. Has worked fine so far (3rd season this year).
