Thanks Steve. I'll try the unscientific method next.

What is tough for me, is that part was bought at one of the premier chandleries in the PNW and it was clearly labeled as bronze. We had just come from an early 1980's boat and had replaced most of the fittings because they were in fact brass so I was sensitive to what I was installing on Hobo.

Thanks for sharing all the great info

Question on one of your pics - what are you using as a coupler in exhaust run in engine picture? I am looking at changing out old ss steel elbows for silicone similar to your setup.

A good choice would be fiberglass.

We're back at it and starting to put things back together. Here's what's been going on:

I was camera-less for a week after dropping my trusty Cannon into the bilge sump so we're missing a few pictures.

The engine rebuild has been delayed about 10 days to 2 weeks. One of the lobes on the cam for the number 5 cylinder was out of spec, so off it went to a specialist.

The tanks should be ready by the end of next week or the beginning of the following week. It took a little longer to get the drawings approved.
When we reduced the capacity from ~700 gallons to 620 gallons, the deck fills needed to get relocated. Fortunately, we caught that just before they went into production, or we'd have been going thru a deck beam.

We're done grinding fiberglass. I don't care how carefully you tent, dust is going to find it's way into other spaces. We cleaned, cleaned, then cleaned some more and there's still dust.

In the engine compartment, after the grinder/sanders were put down and after vacuuming and wiping down everything at least 3 times there was still dust. I think this is one of those projects you only do once. I'm still scratching. We should finish rolling on the epoxy this weekend. I want a maximum cure time before we start the full-on reassembly. More next week.

Greetings,
Mr. LM. That bilge is GORGEOUS! Seems a shame you're going to have to start putting stuff back in BUT a necessary shame I expect. Oh, the camera?

Larry,
Despite the expense and troubles I know those changes are going to bring a smile to your face each trip to the ER. Might even want to have morning coffee down there? Glad you seem back on track with your project and allowing us to observe and learn.
Congrats!!

Glen

OH Boy is that a sweet bottom from any perspective. Could I suggest forgetting about bronze stuff and go with chrome, lots of chrome.

Echoing others, great DIY project you're doing. It will end up better than a yard job by virtue of the fact that you care more than the yard guys as to outcome.

I missed it, what white bilge coating did you select?

We're trying Sherwin-Williams Sea Guard 5000 HS Epoxy based on the yard's recommendation and talking to Sherwin-Williams. I've tried enamels and gelcoat in the past and after 4-5 years the paint has worn through or the gelcoat is dirty and doesn't clean. A 2 part polyurethane is too glossy for us. The Sea Guard is an off white and has more of a satin finish. A potential down side is that it may yellow slightly. Time will tell if we made the right decision.

After all that work, there is no way I'd use anything but a 2 part poly.

If you don't like the gloss look, just flatten it.

Larry, the word is overused these days, but nothing else will do. What you've done is literally awesome. You set the bar high for any who would undertake a similar engine compartment project. Saludos!

KneeDeep: Better forget it. If I know Larry, the extra two weeks in the engine shop isn't for nothing. We've already seen plenty of evidence that he tends to over-do things .....even leans a bit toward the exotic. But he promised to leave the valve cover breather cap red!

Yes, and they should have been changed long before now.
