Maintenance Propeller Care A damaged or unbalanced propeller will cause excessive vibration and a loss of boat speed. Under these conditions, stop the engine and check the propeller for damage. If the propeller appears damaged, have it checked by your Volvo Penta dealer. Always carry a spare propeller and replace the damaged propeller as soon as possible. A rubber hub in the propeller is the shock absorber that minimizes damage to drive units and engines. If the rubber hub should begin to slip, it can be easily replaced at an authorized Volvo Penta dealer or propeller service station. WARNING! Protect your hands from the sharp edges of the propeller blades.
Wear gloves whenever you remove or replace a propeller. Do not attempt to hold propellers by hand when you remove or install propellers and propeller nuts. Serious injury could result. CAUTION! Never continuously run with a damaged propeller. Running with a damaged propeller can result in drive unit and engine damage. Installing the SX Propeller CAUTION! Failure to install all components could result in loss of propeller and damage to drive unit next time the boat is operated. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 1.
