Why 4.3 Mercruiser Cap and Rotor is Necessary?
I have been an avid boater for many years, and I have learned the hard way that keeping your boat’s engine in good working condition is crucial for a smooth and enjoyable experience on the water. One essential component of a boat’s engine is the cap and rotor, especially in the case of a 4.3 Mercruiser engine. Let me explain why.
