The most effective assessment of the quality of transmission and motor lubricating oils for marine engines in general and of outboard motors in particular can be given by practical tests on real engines. An important factor for improving the technical characteristics of outboard motors by reducing friction in the movable joints of the internal combustion engine and gearbox is the right choice of a lubricating oil. The stability of the engine crankshaft rotating speed, reducing noise and vibration during the outboard motor operation indicate good lubricating properties of the engine and transmission oil used. There are shown the results of comparative tests of outboard motors SEA-PRO T2.5 (two-stroke) and YAMAHA F4B (four-stroke) using the most common on the market lubricating oil and the oil produced by KUPPER, LLC (Russia). There are presented the illustrations of outboard motors SEA-PRO T2.5 and YAMAHA F4B. The tests were carried out in the laboratory conditions in a small experimental pool by specialists from the Outboard Motors Research and Production Laboratory of Astrakhan State Technical University. The control and measuring devices used were: a tachometer SEA-PRO TSP-02, a gas analyzer “Infrakar-A-02” with a built-in tachometer. It has been inferred that there is a direct dependence of the crankshaft rotation speed during long-term operation of the outboard motor on the quality and characteristics of the lubricating oil. The probability of the research on stationary propulsion systems in water transport is indicated.
