19.6 1979 Aqua Sport Centre Console. Water sloshing about in front of hull.

[Tristan]

Hi All,

I would like to introduce myself- Tristan from Sydney Australia.

I have just recently bought a 1979 19.6 Aquasport of a fellow Classic Aqua sport member. After a few months of getting to know the boat ad also replacing the 1989 225 Yamaha with a 2005 200 Yamaha the boat is running well except last night after a evening trip I noticed that when I was engaging the Jockie wheel on the trailer I could hear water sloshing about in the front of the hull.

What I would like to know is what is the typical internal setup from a drainage perspective in these hulls? Should there be a drain hole that runs the whole length of the hull?

I am quite concerned about it as I am unsure how long it has been there for and am worried about rot, it sounds like about 10-15 litres of water at a guess.

Any help advice is greatly appreciated.

Tristan

Hi Tristan, welcome aboard!!
If you look at this pic you can see the inside and front area of the center console boat - the 170 and 196 are similar


Here is a couple pics of what a typical early model 12 degree hull would be like - this is my 170.  Here is the floor and casting deck cut out


Here is with everything removed - as you can see there is nothing there to hold water.


Could you be hearing fuel in the fuel tank?  Is it under the sole and toward the front?
Your boat's layout is not standard however so the best bet is to talk to the guy that you bought it from (maybe his rebuild pics are here if you know his username) and see how he closed in the front.  Also, is there anything under the center console? I see it's been raised.

Rick and Triston,
That cap and console are pre '72. Sure looks like a flat back to me. She may be a '69! It's odvious she has a new floor and bow deck as been removed so what's under there may be in question. I'm thinking a pie plate through that small bow deck is going to give access to that trapped water in the bow. Perhaps over time, the bow eye is loose and water has entered that way with no way to drain out of there.

OK,
So this hull was originally rebuilt in Maine but I can't find anything on that.

It was shipped to Australia by member "Woodeneye" aka Sean (who is better known for his 222 CCP).

Water in the bow of an Aquasport is not unique by any means. I would try and position the hull on a decent grade and see if the water will flow to the stern and drain out. The inspection plate is a great idea so you can see down into the hull and confirm or better yet, lessen your concerns.

Good luck.

Hi Gentlemen,

RickK, thanks for posting the pics, its good to see what she is meant to look like. The fuel tank in this set up is in the centre console in the forward area unfortunately.

Fitz73222, I am thinking the pie plate would be a good solution just hope I choose the right spot.

Capt Bob, I will get in touch with Sean before I do anything, hopefully he has the contact details of the guy that diod the rebuild.

Thank you everyone for your help it is really appreciated.

I will let you know how I go.

I think it's the way it is sitting on the roller trailer.  If it was sitting on a bunk trailer the "banana boat" sheer would stand out.  It's definitely a 12 degree model and post '72.  I'm not sure the console is stock - may have been replaced.  Woodeneye is still hanging around, he can help us out on the console.

Hi Tristan & Guys...I have the previous American owners details, but I can tell you from experience he would be of limited help.

I think the inspection port, in the top, is the simplest solution, you could then pump or sponge it out. I would suspect that a little water has found its way in (shipped a wave?) and that perhaps the bow down attitude when sitting on the trailer (your chocking it and raising the the jockey wheel right up to raise the bow when sitting on the trailer right?) has allowed the water to find its way behind and over a stringer and it can't get out. I can assure you it has never had water "up there" before. BTW its not a Flatback and the previous owner who did the rebuild was in MA. I'm fairly sure the console is not original.

Hope this helps. I still can't believe that the original Yamaha let go. Rotten luck.

My bad.

Hey you were pretty close!

What's wierd about this hull is the cap and console are definitely 66-71. I agree that the shear line resembles post 72. See how the inner cap lip runs all the way back to the transom. On 72 and newer it stops about 6 feet before the transom. Plus this cap is narrower than post 72. Triston, if you get a chance, take a picture of transom from the outside and post. Also, cut the pie plate hole on the vertical surface of the small bow deck. This should give you access to the suspect area to pump it out and you won't have to deal with the pie plate leaking if it was mounted on the horizontal surface.

The more I look at this the more I think this is a 19-1, the transom picture will tell what it is.

Cool boat.  I suspect you have a bit of a Frankenstein boat going on.  The cap is clearly from an older boat and the console is as well.  It looks like they build-up the base of the console to accommodate a larger tank.  Water may be trapped in the casting deck area - which is much smaller than on original.  Cut a hole and install a 6" plate to inspect the area.

Good luck

Hi Sean,

Have been chocking it up as high as she will go however it seems to still be there. One thing to note is that it constantly drips and on hot day obviously makes a larger puddle. Rick I will put the plate on the vertical and hopefully that resolves my issue. Was considering getting the storage reinstalled up the front as there is little room currently to store anything.

Will do a bit of a shoot of the whole boat and upload for clarification sakes of model.

Thanks again gentlemen.

Did you try putting a cinder block or two under the jack to get it up real high?  Make sure you chock the wheels.  Give it a shot and let it sit for a while.

[Tristan]

RickK, I am going to do a drop by a few building sites and grab some cinder blocks on the way home and jack her right up. Sarasota, one of the few places in the U.S I have been and I must say I loved it! Wished I had brought a rod!
