In the last comparison test in this class (BOOTE 9/04), only Tohatsu's M 9.8 remained under the 30 kg mark. Its "great-grandson", a four-stroke like all the engines in this test and, together with the Parsun, the lightest engine in the test, weighs in at 39 kg, a whopping 12 kg or, in other words, around 40 % heavier than its grandfather.
It is understandable that a four-stroke engine, which has significantly more moving parts with valve control and forced-feed lubrication, is heavier than a two-stroke engine, which can do without both.
Sail, one of two Chinese engines in this competition, who are bringing a real heavyweight (53 kg) to the starting line with their throttled 15, are relying entirely on the persuasive power of the price.
In this respect, only Parsun's domestic competitors are better. The established manufacturers, whose prices are up to 70 % higher than Parsun's, cannot and will not come close to keeping up. The Chinese concept is anything but progressive.
