    I found a little bit from Glen Wooldridge:

    Over the years, I know of three other companies that have built outboard jets. One was a straight through flow. The name was Aqua-fin. If I remember correctly it claimed 90 to 95% efficiency. Mike Sandeman worked for them at that time and Mike and I did a test in 1984.

    I went thru my test notes and found the test. We used a Wooldridge 16-Plus Boat with a 115 Evinrude with an outboard jet, then switched the boat to an Aqua-fin outboard jet and ran the same test with Mike and me.

    Our top speed with the outboard jet was 39 mph and 37 mph with the Aqua-fin.

    With 1200 pounds in the boat it ran 35 with the outboard jet, 33.5 with the Aqua-fin.
