DYNO MITE - MARINE SUPPLIES UK

Marine Supplies UK has possibly the only mobile state of the art Dyno testing equipment in Wales catering for outboard and inboard engine testing for full horse power output.

DYNOmite marine “prop-shaft” dynamometers are ideally suited to testing outboards and stern-drives right on the boat. These lightweight dynos simply mount in place of the propeller. Accurate, strain-gauge torque readings provide actual horsepower. Its integral computer calculates, displays, and stores RPM, Hp, torque, time, etc.

How does it operate? The lightweight DYNOmite absorber installs, like a prop, on most 50 Hp outboards through 502ci stern drives. During testing, you sweep the desired RPM range by adjusting its load valve. This controls the water level inside the absorber - which changes its rotor’s load (like having an adjustable RPM test tank wheel). The DYNOmite’s computer records the resultant torque at the absorber’s housing (along with the RPM) to calculate: Hp = Torque (in foot pounds) x RPM / 5,252.
