what are these holes?!
 

Today I noticed I was taking on water, while in reverse. Yeah, not too happy about that. Don't worry the boat is fine.

So the water seems to come in through the transom in two holes which are located just inside of the trim pumps on either side of the transom wall about half way to the top.

They are lined holes that are exactly the same size as the drain plug hole at the bottom.

I put my extra drain plugs in them and that solved the problem.

What are these holes for? Why on earth aren't they plugged??

-Ross

could the holes be for the trim tab indicators? :eek:

be sure to quickly glass in the holes..don't want your transom rotting out soon.

Noli- they are glassed and sleeved like the hole for the train plug, so transom rot is not a related issue.

went to look at Gary's transom shot, and don't see anything that would require those holes...maybe Rick knows.

another guess is that the holes could be for the integrated swim platform. leaving them open for any water/condensation to exit thru the holes. When you went in reverse, the water trapped in the swim platform were ejected...now I'm really curious :grinser010:

Noli, hit it right on the head !!!
rbarna, As Noli said, those holes are for any trapped water to get out of the knees of the swim platform.

So why does water come in every time I go in reverse?

Should I plug them or not plug them?

It sounds like water gets in at the bump rail and the drains are by design. Maybe that seam needs to be resealed if you have a lot of water.

In addition to what Pat said, if you open the image above and zoom to 150%, look behind the gentleman's left foot, you will see a vent of some sort...look into that ...or if you have pop-up cleats around the swim platform area check to see where the drain to the pop-ups are directed to...

The blower hose is attached to that vent near the guys foot....

Cleats are in the engine compartment, and Noli. The thing behind the guys left foot is the fan exhaust for the bilge.
And do not plug the holes.

ok, so I'm not supposed to plug these holes... what am I supposed to do to prevent taking on water every time a wave smacks the transom or I go in reverse for more than 5 seconds?

what are the holes for?

Rick, can we shoot foam into the cavity?

If so, we can accomplish all of these items below:

1. prevent water/condensation from collecting in the cavity ever again

2. add overall strength on the integrated swim platform

3. completely reversible, just make a 4 inch diameter hole and scoop out the foam material, then close up the hole

4. save weight, instead of carrying water in the cavity, now only light-weight foam

5. plug the 2 holes for good

6. prevent a drug smugler from hiding bad medicine in there :grinser010:

Hmmm, now there's an idea...:lolhit:

Noli, SHHHHHHHHHHHHHHHH. thats how i move my STASH !!!!!!:grinser010:

...all you guys are being watched now!

your speed boats better not leave US territories!


who's laughing now :grinser010:

rbarma, on all the Y2K's I did the bumprail on, the hull/deck seam was filled with silicone in certain areas to prevent water intrusion. I don't do all the bump rails. As far as a fix. It would take every bit of 5 minutes.
Remove the screws around the swim platform (approx 20) with a screw gun, if you have one. Apply a bead of silicone in the hull/deck seam. Put a dab of silicone on the threads of the screws before you put them back in. Done. That should solve the water problem. Obviously I didn't install your bump rail. Let me know if there is silicone in the seam. I always put a 5' bead on either side of the cockpit, and around the swim platform. As these are the only 3 areas on the hull/deck seam that are inaccessible to glass. If I can be of any more assistance, let me know.

Hauled the boat out of the water, the bump rail seems to be weakly attached to the swim platform and is easy to move and see a gap with your hands. So we're gonna take it off and caulk it.

Ross please take pics of this work to give other Y2K owners an idea of what is entailed in the sealing of the gaps.

No gaps on my Y2K. Built by FX-10 Rick !!!!!!

You are Lucky Gary.
I'd probably still be a Superboat owner if mine had been built by Rick.

I don't have any photos as it was fixed last night by my mechanic.

He said that there were BIG gaps along the rubrail with no silicone at all, it was very easy for water to enter the swim platform and then the bilge.

He said he's sealed both the seam and the joint near the transom.

The drains remain open but it is unlikely for any water to get in now.

Wooo hoo!!!!

Thanks to everyone for help in diagnosing it!

Hey Gary,
Check your boat for the issue that Ross had. Your boat was built just before his.

Ross,

Just one more check, and this should not be an issue by then.

Be sure the cavity is dry before laying up for the winter. Don't want water freezing then expanding in zhere!

Pat, I believe Keith's boat was 2 boats ahead of mine. Once Bitten, Maryland Y2K, Superbabi. (If my memory is correct ? ):grinser010:

Not you brother; Gary from Albany (GORT).
His boat was SB30 (Scott's) and was built before Once Bitten.
That boat took on a lot of water through and over the transome bouncing around in Block Island Sound on one of our trips.

We know Superbabi was built without shortcut...

So now that I have the swim platform all sealed up any other areas I should look at in terms of "short cuts" to be fixed or "improvements" to be made?

Thanks!

-Ross

Never had problem with water washing in the back... boat is bone dry after every time out

The only way for water to come in on my boat is betweem the engine hatch & the swim platform... thats where the engine gets air & the only place so it can not be sealed.... I have never had an issue with water in the bilge or swim platform.... if water rolled up on the back of the boat it would get in the bilge thriough that area.... perhaps that was what happened to Scott?

Don't start rumors about my boat being built with shortcuts Pat.... its information you don;t have & not a good way to make friends....

Pat we all know the Y2K'S that Rick built ( and all the Superboats Rick built ) are of the Best Quality Built SUPERBOATS !!! All the build photos right at our finger tips...................Ahhhhhhhhh the good old Days.:grinser010:

Ditto.:grinser010:

I never said your boat was built with shortcuts.
I was with Scott when he was taking on water in Block Island Sound. His bilge pump failed and he used my manual pump a few times to pump her out. Perhaps it was only water washing between the hatch and transom. You are right, I don't know for sure either way.
I do know your boat was built around the same time as Once Bitten and there was a problem found with that boat. Thought you may be interested in checking it out.
Sorry, if you take offence to my comments.

No problem Pat... I took the comment "We know Superbabi was built without shortcut..." the wrong way because it follwed commens about my boat... the internet! it happens.... Scott had told me the storey of the bilge pump when i asked what the heck is that thing, meaning the hand pump...lol.... anyway thanks for straightening me out... we're good...

It is my understanding that my boat is one of two built in 2004... the other was black & went to the 1000 Islands region...

The " ALL RISE " Was a 2004 also. She was in Toms River for a few years.

Easy guys, this isn't really a big deal...

it only happened once because I was backing up over a long distance many times over a long period (don't ask, it was a crazy day in NYC harbor). And when it did happen, the water came in through two drain holes that were designed to let water into the bilge. It was then pumped out by the bilge pump.

The fix was simple and works perfectly.

No need to get all worked up!

This is an easy group to fire up.
Just start talking about Superboat vs. Progression vs. Activator vs. Other.
Anytime the quality is questioned...:party-smiley-004:
