One year, one race, 3rd place.

Hans hadn't run in a year. We were plagued with unexpected problems so his practice with the new setup consisted of 2 laps and then heat 1. We have minor boat repairs to do from a collision, but everything will be OK, bent steering bar, scratches, etc... So we have some minor boat repairs to make. Drivers from Fla.to Cal. and Wis. were on the course.

Ready to go to the ramp at Baytown for break-in Sunday, Hans Kueffner-McCauley, Finn Küffner-McCauley, Cornelia Küffner, Katie Mccauley, Marianne McCauley. But now it's time for lunch.

Congratulations to Chris Hughes for a fine performance at Port Neches running two props reworked by McCauley and son.

First completely mathematically-designed and -produced prop by McCauley and son. Chapter 5 in the book.

Completely mathematically designed cleaver, hub to tip. Basis is design of a mean camber surface of wing theory. Hans carried this, his first project as mechanical engineer, through by converting my equations to a 3D design using CAD. The CAD program was then fed into the CNC machine of a very good Austrian machine shop. Testing, unfortunately, cannot be before next spring thanks to covid-19.

We are not restricted to cleavers. We can easily design a chopper style of any pitch, camber, and rake.

High speed boats necessarily use surface-piercing propellers,but there is very little literature available on surface piercing. My aim is to quantify what I have understood about speed on the water from theory and practice combined. I’m uniquely qualified to write about the combination of fast pl....

You can look long and hard in the math, hydrodynamics and marine engineering/naval architecture literature and you will not find the equations describing a raked, cambered, marine propeller blade, with or without pitch and camber set on the mean camber surface (wing terminology). The equations exist. Hans has used them to print out a 3D example of an SST45 cleaver, with thickness function added.

Hans'1975 Stinger 75. We're rebuilding this powerhead, it's been in service on the May Fly III since spring 2012. The longest that I raced a Stinger/Hustler 1977-85 without rebuilding was one season, about 10-12 races.

During the mid-late 1950s when my dad was a Mercury dealer and I was the mechanic Charlie Strang (who died last month) and Edgar Rose were engineers at Mercury. My dad and I raced Mercurys in NOA OPC 1958-60 and set 6 kilo records. Along with Charlie Alexander, who stayed with Mercury, they were the main engineers. Charlie went to OMC in 1966, Edgar followed a year later to the date. OMC began producing outboards that competed with Mercury, some outperformed the equivalent Mercury models (the Stinger 75 vs the Mercury 650XS, e.g.). I drove for Evinrude 1977-85. I met Edgar at the OPC nationals in Eufaula in 1977 after I'd won two nationals. He wanted to interest me in propeller theory (he did). At the 2013 APBA Awards Banquet Edgar seated Cornelia between himself and Fred Hauenstein, and me between Barbara and Charlie Strang. I was pleased that Charlie told me that he always trad my tech articles in The Antique Outboarder quarterly.

Rear seats installed in our 1965 Power Cat 15t. Tested two OMC Rakers, both require work: the high pressure blade sides are 'flat' (no camber) with rockers!
