Prevent Boat Propeller Ventilation
If you want to keep your boat propeller functioning the way it was designed, you need to be aware of propeller ventilation and how to prevent it. This article explains this boat malady, and contains tips on how to prevent it.
Identifying Boat Propeller Ventilation
Ventilation is the circumstance where air at the surface, or exhaust gas, is sucked into your propeller blades. When this takes place, your boat slows down, while at the same time engine RPM rapidly speeds up. Boating symptoms of it may include instances of tight cornering, a motor mounted overly elevated on your transom, or over trimming the sterndrive or outboard motor.
Examine your propeller consistently for dented blades, nicks, and rolled tips. Any deviation from what’s normal may lead to poorer performance and also cause harmful engine-damaging vibrations.
Keep Your Boat Clean
Dirt and grime are a leading cause of decreased boat performance. Therefore, be on the lookout for a soiled boat bottom, which may reveal marine growth, barnacles in seawater, as well as accumulated slime, dirt, lime, and other such material. Consistent boat cleaning, particularly during boating season, can help ward off boat propeller ventilation issues.
Once you properly understand boat propeller ventilation, and then go about maintaining and cleaning your boat, you will be doing your best at preventing this common mechanical problem.
