EVINRUDE STORM BOAT MOTOR WWII –

The Evinrude outboards built for the war effort made enormous contributions to the allied victory. The Evinrude 4-60, a four-cylinder, two-cycle racing engine that traced its heritage to the Super Elto Quad of 1928, became the ‘Storm Boat Motor’. Modified from 60 to 50 horsepower and from 6000 rpm to 5000 rpm, the military version featured a bipod that allowed it to be placed in the middle of special Storm Boats that could carry eight soldiers at planning speeds. These powerful Evinrudes propelled the first wave of American across the Rhine – 125,000 troops in a single day.

Was at a long time dealer yrs ago who had a similar motor but I think 2 cyl.
Also for the military.
Had a giant steering whrel mounted to its top and allowed 360* steering like their smaller
motors.

Had an attic full of antiques including a very early electric start motor.
Thirties vintage I think.

Evinrude - Johnson outboards. Facts, history, racing and future.

1939 Evinrude Model 6042 “Hex-Head Racer” This 30 cubic inch opposed twin class “C” motor was the final evolution of the Speeditwin racer from OMC and essentially consisted of the best racing technologies from the OMC stable at that time. It used the six-bolt cylinder heads that were first used on the Speedy-Bee, external rotary valve from Johnson, low friction bearings in the powerhead and lower unit and streamlined lower unit from Evinrude. The basic concept was originally introduced in the prior year as the Model 6038 but inherent cooling problems quickly led to the better-cooling, hexagonal cylinder heads (obviously, the name of the motor was taken from the distinctive-looking heads). Other features included battery ignition with a light flywheel, centrifugal water pump for cooling with the pick-up on the front of the lower unit above the gearcase, open exhaust with heat deflectors and a 13:19 lower unit gear ratio. The motor was originally priced at $395.00 and weighed 105 pounds.
