Anyone seen something like this before?

I find it interesting that Bob McCullough built a supercharger for the Ford V8. When Dad went into sales, Evinrude was using specially equipped trailers as outboard displays for there factory representatives. Dad was driving a 135 Cu. In. Ford V8 60 horse car that had trouble with the load. Irgie Irgins designed a supercharger for dads car. It did a great job and three prototypes were built. Dad took one to Henrey Ford in Dearborn to try and interest him in having Evinrude supply them to him for people wanting more horse power from there V8 60 Fords. Henrey’s answer was they were already working on a larger 225 cu. in. 85 horse power V8 and he wasn’t interested in buying from an outside company.

In any case a planetary gear set up in the base of the radial could spin the supercharger fast enough the supply the radial engine pictured. I saw McMullough’s ad for there outboard of the future. Unfortunately Bob lost a fortune in his risky Realestate venture (Buying the London Bridge) and didn’t have the money the bring it to market. . . . 🙄

I would bet that it has 5 cranks in it geared together….art b

Probably a master rod with link rods – the only variant I’ve seen is the early twenties "slipper rod" style – the Glen Curtiss museum in Hammondsport had a cutaway Rhone Rotary – a radial in which the cylinders rotated en masse – with slipper rods.

I’m dying to know what the power impulses are – does this thing fire each cylinder sequentially – five power impulses per rotation? Seems like balancing would be a challenge.

Very cool boat – does anyone know its length? Looks like 12′ or 14′

A four stroke radial fires every second cylinder in a row but I would think a two stroke radial would have to fire every cylinder consecutively. Notice to that radials are always composed of an odd number of cylinders, 3, 5, 7, or 9 for smoothness.

Here’s some links showing how they work.

The McCulloch radial, being two cycle, fires five times a revolution. . . 😉

I can’t imagine working on one of those Nordberg radial
engines, nor what it sounded like when the crankshaft broke!

Prepare to be boarded!

Mumbles – the Glen Curtiss museum also had an early (1907?) motorcycle powered by a radial engine – a three cylinder rotary engine that formed the rear wheel – the cylinders were the spokes.

something like this:
