Марат! Расскажу в чем сомнение мое. В магазине взял 3-х лопастной винт упакованный в салафановый пакет с бумажной этикеткой к нему. Так вот на ней кроме всякой мутоты есть таблица применения винтов к тому или иному двигателю.И винты 11 х 7, 11 х 8 ставят по ее определению на мотор не меньше 71.Даже винт 10х7 по ней на мой движок великоват. 😃
Но с другой стороны совсем не факт что таблица эта правильная. Так вот в этом то и вопрос. 😊
А может быть, в таблице подразумеваются четырехтактники? Тогда все более-менее ясно.
