where to begin... Engine is in now what....
I have now learned from those who really know.....it is not a good idea to put anything fiberglass within 30 inches of your mixer. If inside this distance ,It may last or may not. use 30 inches....ok. So my fiberglass 90 is now useless. I have about an 8 inch gap. I was uneducated when i bought it...
Tasks to make this part of the project work:
I need to reposition (cut/weld/brace) the stock Volvo 4 inch exhaust riser so the mixer is farther aft and centered. This is not new. This is what seaboard marine did so excellently for Chris, clloyd years ago as per his great posts ..... I need 316l stainless tube for fabricating....nope not around here by the foot. 20 ft lengths minimum. argh. I need 3 ft max and that is allowing for errors. $30.00 a foot...you take 20ft. FaK !
It also seems 5 inch od 316L stainless steel is like unicorns farts, rare in these parts too. At least in any practical length. I can buy a 20 ft section for $180 a foot ! Obviously the local suppliers are trying to tell me something. Plan "B".
I have spent some time kicking tires in the Florida boat scene. So.
De Angelos exhaust specialists in Ft Lauderdale. Florida, the land of plenty when it comes to boats of all shapes and sizes, but often big. 5 inch is big on the great lakes, average in Florida, hence lots of 316l tubing stock.
My 4 and 5 inch tube is on the way to me. Thank you FEDEX air. thank you De Angelos.
Pics are of the 5 in. hole I had to cut. measured about 20 times before I picked up the hole saw.
The fiberglass 90 exhaust I had planned. nope. Anybody need one ?
The 90 will now be 5 inch welded stainless. (solar flux to weld with, instead of purging with argon...) second best i know.
Last pic is a very strange pic threw the exhaust cut out. Not a common viewing angle. I like it. I see a spot I missed scrubbing.
More fun to come. D.
