1989 Hunter 40 - A million questions.
 
Let's face it, I'm going to have questions on a million different things...all the way up until I sell the boat years from now. I've got a crap-ton of stuff to learn...from electrical stuff, to plumbing stuff, to diesel engine stuff, to bedding hardware stuff, to...well...

I might as well start a dedicated thread.

Okay, here's the first one. Though the survey didn't catch it, there is a pretty bad leak in the water tank. I can't quite tell where it's coming from...but the water is coming out from under the tank...especially when it's over maybe 1/3 full. I discovered it when refilling the tank after we'd emptied it over a couple of weekends. I filled it all the way up and it was leaking like crazy into the bilge.

It's a 105 gallon aluminum tank - and has what I assume to be some kind of baffles on top as shown here:

So my question is this...any reason I shouldn't remove one or two of those covers and see what I can see at the bottom of the tank? My hunch is that it's corroded - but I would love to discover just a bad supply fitting on the bottom.

I would do just that , i hope you find a lose hose clamp, and you are not going to have to line that thing.

Those would be inspection or cleanout plates smacky, the baffles would be inside the tank to prevent all the water from sloshing quickly from side to side, front to back. The pattern may suggest the tank is divided into quarters by baffles with a plate over each quarter. There are small openings in the baffles, you just don't want half a tank shifting all at once, creates a big shock load inside the tank.
105 gallons x 8.5 lbs. per gallon = 892.5 lbs. that's quite a water tank you got there.

Smack,
I would remove all the access plates to clean out the tank. I opened up the aluminum water tanks on my 1986 boat and found what looked like gravel inside. In reality, it was not gravel but aluminum salts or something like that. Anyway, I pulled out fist full after fist full of the stuff. Also, some gross slimy stuff. Then I dried the tanks and scrubbed them. I don't drink the water from the tanks, but I feel better about using it and there is less to clog the filters.

Good luck finding and fixing the leak. I hope both tasks are simple.

BTW, I think you have a really, really cool boat and I appreciate your sharing your thought process on finding and buying. Hope you have many great adventures with your fine crew.

Thanks fellas. I'll dig in next weekend.

PS - any idea what that sealant at the plates should be when I put it back together?

Whatever I use, I'd definitely like it to be safe for a drinking water tank.
