The Cool Swirl is designed to eliminate upper
gear problems on Mercury Bravo, Imco, Teague, Max, Konrad and other
out drives. Holding less than a quart of oil, the upper gear case
of an out drive equipped with drive showers can still exceed 300
degrees Fahrenheit with large high output engines. Cool Swirl pulls the oil from the rear cap
of the drive, through a through-hull transom fitting into an
electric gerotor pump, which pushes the oil through a 12”
water to oil cooler, then back to the top cap where it enters the
drive at 50 psi, cooling the gears and 4 different bearings by 100
degrees. The Cool Swirl system
adds approximately 1.5 quarts of oil to your system with no effect
on the drive reservoir bottle. The Nextel Cup Nascar rear ends run
a similar system, one that utilizes an air to oil cooler. Turning
9200 RPM for an average of 500 miles, the gears show little wear.
Actual tests run on the Cool
Swirl will detail the results.
The Cool Swirl sells for
$950 US, cheap insurance against the
likelihood of drive failure under extreme conditions and
staggeringly high repair costs. An optional drive temperature gauge
is available for sale for those who would like to see the
difference with their own eyes.
Test Date: August 15, 2005
Test conducted by: “Doc”Holliday Racing, 410 N. Helena
Street, Spokane, WA 99203, 509-220-9493
Air Temperature: 90 degrees
Water Temperature: 75 degrees
Boat: 27’ Advantage Victory
Engine: Blown 540 ci 1200 HP
Drive: Imco SC with water-cooled top cap
Without the Cool Swirl at 5500
RPM, the drive oil temperature ran between 280 and 290 degrees.
With the Cool Swirl engaged,
the drive oil temperature plummeted down to between 170 and 180
degrees, a full 100 degree drop!
