When a boat suddenly loses thrust, engine RPM rises without matching acceleration, or the propeller shows unusual surface damage, many operators assume the propeller is simply worn out. In reality, the problem may be propeller cavitation. Cavitation is one of the most misunderstood issues affecting outboard motor performance. It reduces efficiency, increases fuel consumption, shortens propeller life, and may even lead to expensive repairs if ignored. Although it is often confused with ventilation, the two problems have different causes and require different solutions. В этом руководстве, we’ll explain what cavitation is, what causes it, how it affects your boat, и ...

When the boating season ends, many owners focus on winterizing the engine but overlook one of the most important components below the waterline—the outboard motor propeller. Proper seasonal maintenance not only protects the propeller itself but also helps prevent hidden damage to the propeller shaft, gearbox, and seals. Whether you use an aluminum or stainless steel propeller, spending a short amount of time on inspection and maintenance before storage can reduce unexpected failures, improve performance next season, and extend the service life of your outboard motor. This guide explains exactly what to inspect, clean, repair, and prepare before storing your ...

Most outboard propellers include important information such as diameter, подача, rotation direction, hub type, and manufacturer codes. While different brands may use slightly different marking formats, the basic sizing system is very similar across the industry. В этом руководстве, you’ll learn what each number means, how to identify the correct propeller for your boat, and when changing propeller size makes sense. Where Can You Find the Size Marks on an Outboard Propeller? Propeller size markings, indicating diameter and pitch, are typically stamped directly onto the outer hub, blade roots, or the rear face near the mounting nut. Common Locations on ...

Многие владельцы лодок не замечают повреждения гребного винта до тех пор, пока их лодка не начнет чувствовать себя по-другому.. Возможно, ускорение становится медленнее, расходы на топливо увеличиваются, или руль начинает вибрировать после удара о скрытый камень или плавающий мусор. Знание ранних предупреждающих знаков поможет вам избежать дорогостоящего ремонта и обеспечить эффективную работу вашего подвесного двигателя.. В этом руководстве, мы объясним 5 most common signs of a damaged outboard propeller, почему они имеют значение, и когда придет время заменить ваш пропеллер. Why a Damaged Propeller Should Never Be Ignored Ignoring a damaged propeller turns minor efficiency losses into severe gearcase damage, skyrocketing fuel ...
