Spring Boat Maintenance Guide

With spring just around the corner, basic boat maintenance should be top of mind as you prepare for summer adventures on the water. Today’s boats are complex machines with computerized engines, electronic controls, power-assisted hydraulic steering, and state of the art navigation systems. But, even with advances in technology, basic seasonal maintenance is still a crucial step in avoiding common problems such as a ruptured cooling hose, an electrical short, a clogged fuel filter, or a broken water pump impeller. These are a few basic spring maintenance tips for your boat from our Sierra experts.
