It's just way too cool to get caught up in the other threads.

What!!!! I don't believe it. You have Old Blue!!!! I'm planning to tell the story of Old Blue later in my narrative. I'd love to have her back but then she would probably just sit out in my garage from then on. She really deserves to be put in a Mercury place of honor for all to see, like maybe the lobby down in Fond Du Lac. Hopefully someone from Mercury will see this and contact you. If not, I will certainly take her. For those of you who don't know what we're talking about, Old Blue was the very first sand cast V6 we made during this program and was the strongest, most durable, best engine of the bunch. Many, many tests of all kinds were run on her and she never faltered. Thanks for taking her in to keep her from the scrap pile.

She was destined for the scrap heap in Oshkosh during one of Wilbur's clean up campaigns, I sent it to the Lake to save it. When the Lake closed she went home with me. She has an inline 6 driveshaft housing and gearcase, 4 cylinder OMC carbs, the distributer hanging off the side of the block, and still has the rust stains from the PLT 6 test tank. The poppet valve and other things are remotely mounted, there maybe other parts missing, and there is no cowls. The adapter plate is hand made V6 to inline 6. It also bas plastic windows in the side of the reedcages to photograph the action of the reeds. I also have all the Lake X test request log books from 1963 to 1978, which includes the endurance testing of the 951. Now that I am retired , they are for sale.

Instead of selling them I'd suggest just giving them to someone and charge them the last few decades of rent. This will probably keep the corporate clowns from harassing ya.

John, Yes...I agree these need to be passed on to someone of honor, with the capacity to correctly preserve them, such as the likes of Sam Cullis(aka Mark 75H), or our very own Greg Terzian, of Scream & Fly.

Somewhere in here I feel like there is a picture of a v6 on a inline mid, or a discussion about it.
bottom line is we need PICTURES2023 TUFF 25

I don't have to worry about the corporate clowns anymore, I retired from Mercury May 24 and started with Seven-Marine June 3rd. After 45 years , no regrets just fond memories and a lot of good friends. Time to make new friends all over again. JFL

Back to the design --- Before I could get on with the evaluation of the three different cylinder configurations, I really had to know what the minimum cylinder spacing could be. Therefore I decided to build my own “Jante Fixture”, (as it later became known), so I could experiment with different transfer passage and port shapes which would allow relatively close spacing. The model shop made the parts and I put them together and set up my fixture in a little room there in plant 6, not much bigger than a closet, but where I could be alone and not be bothered by phone calls, etc. For the air supply I used the pressure side of an old canister vacuum from home, that my wife didn’t like, and controlled its’ speed with a variac voltage regulator.
First, I flowed the Husky cylinder, and, as per Jantes’ paper, it had an excellent pattern. This would serve as my reference to strive for. Then I built a fixture with removable side pockets in which I could insert RTV molded passageways of differing shapes to simulate the passageways for the new engine. I played with different shapes for a solid month, sometimes moving forward, others back, until I was finally happy. I found that it was relatively easy to get a good pattern but very hard to get one and at the same time have a very low restriction passageway. I also had to take account of the fact that the parting line for the production molds would pass right thru the transfer port and so the sides had to have at least minimum draft. In the end I had compacted down the transfers and then rotated them about 30 degrees so adjacent cylinders could nestle together to a cylinder center distance of 4 3/8 inches with the 3 1/8 inch bore. This is what I would base my rough layouts on. (more later)Last edited by rckid74; 01-20-2020 at 12:48 PM.
