deck drains

Postby Catch22 » Sat Dec 09, 2017 12:17 pm

Does anyone have a solution to the water that drains from the deck into the engine compartment? The drains are elbow pipes under the deck that drain directly into the engine compartment and I am looking for a resolution to keep water out of that area if possible. I know the bilge will kick in when there's too much standing water, but wonder if there is a way to avoid the problem?

Would be a great big help if you indicated what boat you have, what year, where docked, you will get a lot more helpful posts if everyone knows what boat you are talking about. On our 4160 the aft engine compartment cover drain fittings exit thru the gull wings on the port and starboard side of the vessel, does not flow into the engine room bilge but that is only in our case, not sure about your situation.

I assume its the 2500. The only way to do this would be to put a thru-hull above the water line to drain them to that point. You can "T" other drains into that one or put one on each side. Always fun to drill a hole saw through a new boat around the water line. ;) If there is another thru-hull already you could T into that if its large enough. However you would want an inch at least or more to get the water through it quickly, maybe even 1.5" for the drain. That larger size would get more critical if you add additional drains to that run. I am surprised that they didn't take them out overboard from the factory, as that task is much simpler to do when the deck is separated from the hull.
Thanks, Chris

Thanks Chris. I had a Chaparral previously, and every drain ran out of the boat, nothing drained directly into the hull/engine compartment. I agree, this should be something done at the factory. If there is no issue with water freezing inside the boat and causing problems I’ll have to let it go (I keep my on a lift in the water year round). But I may resort to finding a way to get to the drain plug and draining it out just to ease my mind, even if the result is hypothermia from getting in the water. :lol:

Depending on where you are cold wise it could easily freeze if its out of the water. That is why you want those deck drains to have straight runs overboard so that there aren't low spots for water to sit and freeze.
Thanks, Chris

My 2011 2100 is like this. Deck drains right onto the carpet ahead over the rear seat storage areas. It's like the dealer (or Regal?) forgot to install some sort of drain.

I ended up attaching some flexible drain hose to them, and routed them to the bilge. Not ideal, but its better than soaking the carpet. That said, I don't know that these drains are high enough to route to an external through-hull on our boat, but maybe they are on a 2500?

Either way... if you're in a freeze-prone area, I recommend flushing these with marine anti-freeze during winterization. Will help to clear out raw water and hopefully prevent your drain tubes and possibly bilge areas from freezing.

Chris, just for fun = If is below freezing it would be snow and if above freezing it would be rain? :) Sorry, just was in the mood to poke a little fun! Your posts are extremely informative and factual. Where did you get all the experience on Regal boats (or boats in general)?

Happy holidays!
