With the success of the High Speed Quad ELTO motors, ELTO released High Speed versions of their 2 cylinder the High Speed "Speedster"
OMC literature designates these as model numbers 302 and 303 for 1929 models
If anyone has pictures of these models it would be appreciated

The original Evinrude company no was longer owned nor run by Ole and Bess Evinrude, but Evinrude's new owners didn't want to be left behind so they started a racing program as well.
1929 Evinrude "SpeediTwin" Models "US" and "UL" were the first racing Evinrudes. Model 147 Speeditwin was probably a late 1929 model. I'm not sure these motors had anything besides a bigger carb and some porting/head work.

Over at Johnson the Giant Twin racer stayed on as the TR-45
Real news showed up with 2 completely new racing powerheads
A 39.87 ci opposed 4 pulling up to 36 hp @ 5,500 rpm with rotary valve intake timing and a big Vacturi AO500 carb, the VR-45
And a class B 19.93 ci rotary valve opposed twin motor, the SR-45

For today I have some images of boats of the 1929 - 1930 era
Check out the steering in the Penn Yan. All outboard boat remote steering derives from these early racers; steering wheels and remote controls were not used on fishing outboards until some time in the future. I think the motor is the VR-45 Johnson I mentioned above.

Your posts in this thread made my week.
They evoke a wonderful era of a great engaging sport that in recent decades has entered the doldrums.
In recent years I caught some of that old feeling spectating at region 10 C Service heats. Their low register growl (and that of their big brother 4-60 F motor) is almost (but not quite) as pleasing to my ears as the scream of an 1100 6 cyl alky Mercury.
