Inner/Outer Hull Drains

[Dick@merrittmarine]

Codfish, On our 210s we use a 15/16 paddle bit and drill 1 1/2" up and 1 1/2" over to the stbd. side, when were thru the hull we hog some of the foam out to make a small pocket, about 5" or 6"deep, 2" to 2 1/2" wide.
The hole location doesn't have to be exact, Just close. One drain is sufficient.

Well, I did the install last night. Used the black plastic drain out of the West Marine Catalog. Simple and clean. One thing though, make sure you drill the hole at least 2 inches to starboard of the keel line. I did mine at 1 1/2" and the 15/16 paddle bit just hit the stainless piece that lies in the keel line. I will post photos if anyone is interested? By the way, I only had a few drops of water come out.

Thanks for everyones input. Especially MMD and LDF.

Codfish,
Pictures would be great for us more visual learners vs. tech jargon. This has been a much discussed but nothing very detail pictorial documented as far as the actual modification is concerned. Please step-by-step it for us.

Gator, and you visual guys,

I will post the pics in the Modifications section since I don't know how to attach them to this post. Here are the written details. (Maybe someone with the knowledge, can move the pics to this post for me?)

I measured for the center of the 15/16" hole by making a mark 1 1/2" up the transom, to the starboard side, from the center of the keel. Then I measured straight up vertically 1 1/2" from that point. The photos will show that this is very close to the center of the transom, just far enough to the side to avoid the piece of stainless that is is the keel line. I would suggest you use 2" for the first measurement however. When I drilled the hole the paddle bit just knicked the stainless center piece and made the removal of foam inside a little harder than it should be. Also it will move the plug mounting screw away from the stainless plate. No photos of the raw hole placement, sorry.

I mucked out as much foam as I could with the paddle bit, let the area dry overnight and then vacumned out the foam still inside. I used a painters can opener to scrape the foam out from inside the cavity.

I then put Rule around the backside of the plug flange and the entire surface area that would contact the transom. I used the wiggle method to be sure the Rule was evenly spread inside the hole when the flange was inserted. I used 1/2" SS screws to attach the plug flange. That length screw will not penetrate the outer transom wall and create a possible leak point later on. I made sure the screws were snug but be careful not to over tighten. I then put a bead of Rule all the way around the outer edge of the flange to be sure of the seal. As Dick cautioned in this thread, the transom is not absolutely flat and a good layer of Rule is important to be sure all the space between the flange and the transom is filled. The additional bead of Rule around the outside was just for more peace of mind on the seal issue.

Viola, a clean, functional install. Took very little time.

Thanks Codfish. Great step-by-step and the pictures helped alot.

I drilled out my transom 2 weeks ago, it's still dripping out a drip about every 2 seconds or so i'm not in a rush so i''l keep letting in drain.I have a question dick at merrit said he cleared out about 5 or 6 inches deep of foam? I have about 1or2 inches of depth in the hole then i have more plastic, are you supposed to go through that also. let me know if you can thanks dick...

STOP DRILLING!!!! You could be hitting the bottom of the hull, or the center stringer. What you have done is good enough. You want to create a pocket for water to accumulate. just put your drain assy. on with plenty of Rule.

wow, you guys got me worried...I thought of the drain plug, then since I was upgradeing my fishfinder, as I pulled out the transom scew.....dribble, dribble, drip, drip,....then I sucked some out....nasty stuff don't recommend doing that ...LOL Yuk. So I think taht the inner hull drain should be a must.....But I am a wimp, I will have the dealer do..

Hello

I am purschasing a new 2005 210 CC, and inquired with the dealer about having this done before I pick-up the boat. They stated taht they have never had a problem, and "thought it was overkill." I did not press the issue in the near-term, but would like one of the dealers or owners to validaie that this should take place before I pick up the boat in two weeks.

Help!?!

I decided that I was carring a lot of mistery weight on the port side and decided that it must be water between the hulls. Therefore, I decided to install a garboard brass plug on the port side of the stainless keel plate. (The boat is very slow getting on plane and it seems to lean to port when up on plane, I have to use the port planing board to level the boat.)

Drilling the hole went well, however, when I drilled through the outer hull about 3 to 5 gallons of water come pouring out, which caused me to be a little alarmed. So, I started looking at the bottom of the hull for a crack or hole. I found a small hole through the outer hull on the starboard side about 2 feet forward and just to starboard of the first bottom strake. (I figure I got punctured by a tree top while crappie fishing earlier this year.)

I plan to fill the puncture with Rule and watch it to make sure it stays plugged, is this a good repair or do I need to have the hole welded? (Nearest dealer is about a 5 hour drive.)

Could that much water have come from any place else? Any advise or suggestions would be helpful.
