Important Summary of Anchor Locker Drain Issue - Attention FSH and 21 Foot owners!

[MrMoose]

@micj, you should give your dealership's service department a shout-out on the forum, because it seems like they repaired it properly, in my opinion. Others who want Yamaha to repair their problem properly can use your dealership as the precedent. Thanks for sharing.

 

[micj]

I will gladly give a shout out to my dealer. M2O Marine outfitters in San Diego. They are a true marine dealer and not a motorcycle/watercraft dealer that happens to sell boats. Ian Morton was the salesman who let me test drive a boat and delivered my boat to me a local reservoir and cruised the water for two hours making sure I was comfortable before leaving and Brett Stadler is the service manager who took care of the issue I had.

@micj, if you have a Yamaha claim number available to share for reference, it would probably really help out those who are seeking to have their drain repaired properly by Yamaha. It should make things easier for Yamaha, the dealerships, and the owners.
Thanks

I just checked my boat and there was a small gap around the hull penetrator. I used 5200 and filled the gaps. ( See pics)

They had to fill the void with fiber glass.

I would love to see this.

On a more positive note, @swatski, great idea to use a pic to demonstrate your perspective. I just thought that the three actual pics at the top of this thread were pretty self explanatory. I guess that I'm a crappy engineer and teacher.

Wow I been away and miss all this heat

 

[swatski]

Yes, you've missed the point. Seriously. Look at the pics. It's not the spacing between the outer hull and inner shell that is changing significantly, one has hard filler between the two surfaces, the other has none!!!!!!!!!! ^#$%^#$@%^%ck!!!!!!!! The factory fucked up and omitted the solid/structural fill on some boats, and in my opinion, that's a problem that Yamaha should fix.
So far one dealership has appropriately diagnosed and corrected the problem. Use that as precedent if you see that you have a problem once you pop out your drain fitting to inspect that space.
@micj's dealer recognizes that you need something solid in the space between the outer hull and inner shell, so they filled it with fiberglass before reinstalling the drain fitting.
OMFG, you guys are killing me!

[EDITED for clarity]
The Yamaha hull is not really double. The pre-2015 hull has a single shell/fiberglass sheath forming the bow with an anchor stored in a "bucket", the 2015+ has a liner/inner shell forming the anchor locker. In the pre-2015 240 the anchor locker had only partial lining, so an anchor getting loose could punch a hole in the hull (in the bow), which has actually happened. The 2015+ boats have a full-er lining, but it is still a lining. At some points that lining (or inner shell) touches the outer shell/hull, and at some other points it does not.

In other words, Yamaha improved on the pre-2015 design that made the hull shell in the bow vulnerable to be damaged by a loose anchor. As @MrMoose first indicated, they should have made the drain waterproof from both sides - outside the hull and inside the anchor locker.

In @MrMoose's picture of the singular material in the opening is the hull and the lining pressed together, as in the schematic below. It appears that in (most) new 210s the drain penetrates the bow where the outer shell (hull) and inner liner (inner shell) are apart.

Oooooooooohhhhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!! I just looked at the void pic again. I thought that the white rim on the far side of the pic was the outer hull, and to me it looks really thin...........BBBBBBBBBBBBBBUUUUUUUUUUUUTTTTTTTT, it's actually the inside edge of the drain fitting!!!!!!!!
Wow! @swatski and @Julian I think that you guys are right.
Hanging head in shame.

 

[MrMoose]

Originally, I thought that @icmd's picture was with the drain fitting removed... mistaken.

 

[MrMoose]

I'm going to edit my original post to reflect that the fitting is not removed in the "void" pic, as I originally thought.

 

[Coheeba]

So let me see if I get this right the void is not really the void in the first picture it's really the plug and not the void and in the in the second picture the void is really not the void and it's really the plug is that right

This is what we need to install and get rid of the existing thru-hull fitting.

@MrMoose this is beautiful. I edited my posts above to better fit with your schematic - great resource!
Maybe you would be wiling to also move your tube insert trick here, or link to it.
Thank you. Very useful schematic.

I cleaned up the old fitting and used a piece of tubing to help keep the 3M5200 from plugging up the drain hole. I'll yank the tubing out tomorrow morning once the 5200 has firmed up.

Here's a pic just before applying the 5200:

Here's a pic from the inside after I gooped a bunch of 5200 around the fitting:

 

[Coheeba]

I just called www.cyclespringsonline.com a great dealer in Clearwater and spoke to a tech and he said there have been some issues with the smaller boats but none with the 242's. He said putting 5200 on it to stop water intrusion is adequate for the 242's.

micj were you getting water in the boat like this...

Yep, this is exactly what has been reported, starting last year. Here is a pretty comprehensive report from @Reefdonkey: https://jetboaters.net/threads/new-ar210-leaking.12003/. Seems like he has had a very similar amount of damage. Good news is - it is a easy fix, and it all dries up (it is a boat after all), but it's a shame you would have deal with this with a new purchase.
