A4 exhuast hot section rebuild

68 - Hot section looks good!!

Agree with Dave on the anti-siphon...I would just get the pre-built Marlon, although that may hold together as long as the hot section!
And, yes it is typical to need to visit multiple stores when cobbling this stuff together...one rarely has every part in the correct diameter/length.

Looks very much like, if not identical to, the anti-siphion sold by MMI.

exhaust rebuild

I am mid-rebuild of our Tartan 27 exhaust. I finally found a high-temp pipe dope (for locals: Hillcrest plumbing in Vancouver - they have 30 cans in storage selling for $10 CDN each...in the t.p. closet).

I am having difficulty getting the pipes aligned in the boat. Wondering how tight the connections have to be when using pipe dope? Hand tight? Harder? Using 1.25 black steel.

Thanks!

When using the black pipe I have installed barely hand tight IE almost loose fittings and after a few run cycles they are rusted and stuck (sealed) in place quite nicely. The problem with the sealants is they do not allow the water into the threads so "rust sealing" can take a longer time to burn out the sealant. If you can actually "tighten" using sealant is not a big deal either way however it is a PIA to get everything pointed in the right direction and get it installed.
