Hello -I have some questions about my twin turbo build which I'll post eventually but first I wanted to share the backstory of my project for those who are interested.
Back in the 70's/80's when I was a kid growing up along the south shore of Lake Ontario there were a ton of Glastron Carlson jet boats all within a few miles from each other, including the CV-19 my father owned. My next door neighbor "Doc" had a 1972 Carlson CV-21 which was unique because that was the only year they came in green metal-flake so it stood out when all the other Carlsons were either gold or blue. That boat was also unique because he was running a Gale Banks twin turbo 850HP kit and it was the fastest boat in the county for years. The boat ran around 90. For years I spent my summers riding in his boat while we raced and blew the doors off anything that had an engine.. it was a blast and by far my favorite childhood memory! The only problem is all the racing we did came with a price.. he blew the engine 6 or 7 times within the 15 years he was running the Banks kit. In 1992 after the 7th time, he sold the boat with the stock 455 olds and sold the blown engine for parts. I was 14 when he sold the boat and that was the last time I ever saw it.
As an adult I spent 10+ years looking for it. Posting craigslist ads, buying boat trader mags, I even wrote a letter to the person who bought the boat back in 92. He said he sold the boat to a co-worker who then traded it for a snowmobile. My dream of owning this boat was pretty much shot especially since finding ANY CV-21 nowadays is rare and especially since they only made a green CV-21 one year.. 1972. I was looking for a 1972 CV-21 aka needle in a haystack. Fast forward to Oct 2011.. I found one! It wasn't Doc's boat and it wasn't pretty, but it was a 72 CV-21. I had it shipped from Missouri to home and together with the help of my father we fixed the stringers, put in a new floor & interior and made a replica of Doc's "Mint Pati" (minus the turbo'd engine).
Here are some pics of Doc's boat from 1979
