Yeah it's hard to argue that Ford red with a touch of chrome doesn't make an all white engine space pop.

Especially with nice bright lighting.

Larry - I was sharing your pain a couple of months ago. I basically followed D'Antonio's advice for tank isolation as well as providing an air gap to allow circulation under the tank to prevent/minimize condensation. I wound up using starboard slats to provide non-porous support. Used 3/8" thick scraps my yard manager donated for the cost of a burger and a beer.

I'll see you next week. Want to see the cavern when tanks are gone. Impressive amount of work in a short time, Larry and Lena. Captain Dons urging , rings true.

Are you planning to coat your new aluminum tanks?
The tank fabricator for the tank I had replaced a few months ago recommended a coal tar epoxy coating.

Looking forward to seeing you also and thanks for the use of your utility trailer. I delivered the engine to Bomac with it this past weekend and will use again on Friday to get the tanks to RDS in Perry, FL. We owe you a dinner at least.

We talked about to coat or not to coat the tanks and decided not to. I was concerned that after coating the tanks, that the finish would be scratched or gouged putting the tanks back in. This would allow water/moisture to get under the coating. After getting the first tank out today, there is no way we'll get the replacement in with out at least scratching the finish. If the tanks were going in easy, I would probably coat them as we did on our last boat.

My understanding is that as long as the tanks aren't sitting in water or moisture, that's what the GPO3 is for, uncoated aluminum should be fine. Steve D'Antonio and David Pascoe have both written articles about installing tanks. I've read both and they seem to make sense. Hopefully the tanks will be good for another 30 years.

The first tank came out with a little more work than I had figured, but it still less than a days effort for 3 of us. As it turns out there was no way we were going to get the tank out in one piece and we did try. We just couldn't rotate it to slide it out diagonally. So, time to get the sawzall out, not once, but twice. When we were done, the tank was 1/2 shorter than the floor board opening.

Once we got the tank free, you could see rust where the fiberglass coating of the tank had been compromised. From the looks of the lower, inside edge, it was only a matter of time before the tank leaked/failed. The top had some water stains/rust but was solid.

After the sawzall, the nock-off fein tool was indispensable.


Tomorrow tank 2.

Good work Larry! I only just found this thread, after we exchanged emails about your plans. Good luck with everything! Wish I could be more help but, the PO did the heavy lifting on my boat. Not sure what product he used to protect the tanks once installed. Fingers crossed that he did it all correctly!

That would be very yachty and unique as well.

ALL Leman's MUST be red and have chrome valve covers! It's the law! ;-)

KK42 Tank replacement

Larry

We are just back on the grid so am a bit behind on this thread.

Golden Dawn's (KK42-82) tanks were replaced by the previous owner in 2001 after a sinking. The two tanks were replaced by four aluminum tanks. I will hunt down the photos and post tomorrow.

Thanks. I'll look for them.

Your PO definitely did a nice job that's for sure. I have to believe he did it right from the way your engine room looks.

The tanks are out! The port tank was definitely a leaker as you can see at the forward bulkhead.

Also, it was very considerate of the builders to leave that extra sawdust to absorb any liquids that spilled.

Next, we figure out the new engine room configuration.

Larry, I'll be curious about component placement, storage, and flooring configuration. I knowthe built in non continuous fiberglass boxes on the flooring were a pain to me.

Man, you guys (gals) don't mess around on your projects! Looks like y'all are almost halfway done. Impressive.

Conversely, I will sit here for weeks stressing over painting my window frames. 😂

The forward ones we are looking at keeping. The 5 battery boxes for the house fit there. I may cut ~3-4" off the inboard side though.

The aft starboard one, where the water heater was, we are thinking we will remove it. We'll relocate the water heater to the end of the starboard tank. The domestic water pump, I'll mount to the covering on the tank wall.

The aft port platform, where the water lift is, we may shorten and move outboard a little. The engine start batteries, we may put at the aft end of the port tank. We've been using Optima's, so watering isn't an issue like the house bank.


This is todays plan away and you know what that means. lol

We haven't figured out where to reinstall the water maker yet though.

Thanks Dude. We found the leaking tanks in May and hauled last week, way to much time to think about it.

I've been a PIA to everyone who said they would help and right now we're holding their feet to the fire (nicely). We've got a great crew. Now it's up to the tank manufacturer and Bomac for the engine rebuild. For the next few weeks we have a lot of what Lena calls, "fussy work".

Nice, for the water maker, the membranes dont like too much heat. I considered putting the membranes in the lazz on the bulkhead and all the other components on ER side... Now I just have temp sensors & alarms in ER in case the blowers were to fail w/o me knowing. Oh I'm so enjoying this!!

Golden Dawn Tank Removal & Install

Larry,
I have 17 photos of old tank removal (probably too late to help) and new aluminum tank install. The new aluminum tanks are 800L & 300L fore & aft on each side.
