All new brass valves with SS ball/stems, new hose for the most part and we kept the copper lines mounted to the forward bulkhead. We've been talking about reconfiguring the system but that will have to wait. We're at the stage of just trying to get things done and avoid project creep.

Thanks. The hose barb won't accept two clamps, too short. It does have a 1/2 clamp on it though. That's one of the reasons to go to PEX, more robust connections.

I was thinking more of an extra clamp to secure the body itself to the bulkhead...

It works!. I've done this for years and use a shop vac to clean up when new batteries put in.

Yes it does. It also helps if you put DriDeck under the batteries to let air circulate under them.

Thanks for checking. There's a SS bracket with rubber standoffs for the tank mounted to the wall with 2-#10x3/4" screws. The hose clamp goes behind that. It seems pretty solid.

I bought this expansion tank 7-8 years ago to replace the Jabsco that cost $180. We paid <$50 at one of the box stores. Maybe the difference in price is the marine industry calls it an accumulator tank and the domestic plumbing folks call it an expansion tank.

I just came across this, it actually explains the difference between the two well.

I think only on the installation, from what I can tell. There is no difference in the construction according to the article.

The item can be used in either application (accum. or exp.).
On a boat, in the cold water system its function is to increase the volume of the piping system and reduce cycling of the cold water pump. In a hot water system it is catering to expansion of the water as it is heated and prevents over pressure arising in the hw piping.

We're done or will be in another day. The engine was on her bed by 10:30 this morning and fuel in the tanks by 2pm with no leaks. Now it's just hooking up hoses and the engine electrical. We splash Wednesday afternoon and move to Ortega Landing Marina Thursday. Are we ready?

I have one more post planned where I'll try to give an accurate cost breakdown. Maybe next week.

I want to thank everyone for the suggestions and support. I maybe able to revert back to a normal sleep cycle now.

Touchdown! Terrific, Larry. What an awe-inspiring account this has been. Thanks so much for letting us [virtually] share the experience.

Figured something out after the fact. It just so happened that, on Sunday, September 11, I was having lunch at the Sand Dollar Restaurant on Ft. George Is., and spotted a salty-looking KK-42 easing in to the St. Johns Boat Co. Nudging my companion, I said, now there's a very fine cruising trawler.

She's one heck of a lot finer now! Saludos!

Awesome job, and one of the most timely projects of this size I have ever seen. Of course I know you have been out in front of this with planning and scheduling extraordinaire. It really makes all the difference when it comes to the Boat Yard Blues, but you set the bar.

3 days is enough for the new mounts to settle, alignment after splash? Any time for her to regain her "in the water" shape?

Very nicely done,

Damn Larry! You guys don't mess around. Congrats!

I'm not posting my stupid little projects (that take longer than your major project) anymore.

Awesome acomplishment, and timely compared to most tank replacements I know of, not to mention all the other work included in making Hobo's ER the sexiest of all 42's. Sincere congrats!

Nice job. It took me 2.5 years of long weekends to do what you did. I riped all the old copper out and went with 1/2 PEX. Cheap and easy to work with. It will out last me and I doubt it will leak. Go for it in the afternoon!
