First my disclamer....
It has been years since I installed mine, only installed 1 set, and I have never seen the cut away of a 210 hull... A call to either the factory, Heartland Marine, or Merritt Marine could bring you up to speed on the "modern placement or placements" locations for the drains. I also used the same type of drains (not those black plastic ones that you can loose) that are seen in the photo section for my present 190. Trust me, those are the only ones to use since they are self retaining and seal up so well

As I was advised by the factory when I installed mine (and really it was quite a simple process), there is a steel bar that runs along the keel. Thus to get the most drainage 2 were needed. Now maybe when they heard how it sounded like a sponge when I walked on the Mega Hold deck, 2 drains were logical / needed to remove all that water? I don't know, but I just saw the third owner of my old 210 the other day at the ramp (small world) and though the boat was not present, he told me that she was doing great, loved the boat, thus I must have installed them correct

• The install locations for mine were 1 inch up and 1 inch over from the center line of the keel so you would miss that metal support bar. So measure twice and cut once as they say
• I used a 1 inch wood bit and it went through that material in nothing flat so no need to push like you are trying to drill through a chunk of Oak,
• I only went in far enough to install the drains which is like 3 or 4 inches, but use your drains as a guide. I dod not pull one of the round out manuvers to make a pocket with the drill bit one the bit was inside the hull as I have heard others do.
• Jack up the boat using jack stands and blocks in combo so you can get it at least a foot higher than you normal highest parking position and let it drain and or drip till dry (mine took well over a week) so that any water in the lower forward bow section will migrate aft.
• Then go back and install you drains with plenty of RULE (but not gushing amounts so the drain does not work) and install your mounting screws. Quite simple really!

Couple of things to remember...

1. My old 210 was FULL of water (I suspect many, many, gallons of water) and though heavy did not sink and maybe sat a inch or so lower than normal when at rest in the water. So if you do not get a good seal with the rule on the drains, no big deal for she is not going to hit the bottom
2. One can always pull the drains back out, clean up the area and reinstall them if you do not like how they look or feel they are sealing.... In other words this is NOT a one time shot at installing them.
3. If water got in there before, more than likely it it will keep getting in. So when you pull it out of the water AND still get some drainage or drips after the hull is drained they first time, I would not sweat it... As I have stated several times in the past, from the ARK to the USS Enterprise they all leak water...
4. I did not have a cover on my 210 before the drains were installed and we got blasted that summer with a ton of storms (the ones that have numbers or names with them ) and rain. After I got the cover on the boat and was able to keep a lot of the "feet" of rainwater we were getting out, from that point forward I only got drips out of the drains and always left them open and the hull jacked up as high as possible when parked.

To me from that point forward the problem was SOLVED and I did not spend a lot of time of effort on trying to find all the tiny little spots that water "could" be getting into the inner hull. Here again, if you are only getting dripping after spending all day or days on the water maybe even getting caught out in the rain or heavy seas then who cares..., For the problem of all that weight (the real issue) is now gone / fixed since you can from that point forward remove any small amount of water that may return....

Hope this helps?
