New Marine-Grade Alternators for Boats and Personal Watercraft

Marine environments require a special kind of alternator - one that's designed to handle damp and humid conditions. Marine-grade DB Electrical alternators come with plated fans, pulleys and hardware for corrosion resistance. Where applicable, our marine alternators come with flame arrestor screens to meet Marine SAEJ1171 certification. We make no compromises in the materials and craftsmanship that go into our alternators, ensuring exceptional dependability when you need it most. 

DB Electrical is a leading seller of alternators designed for boats and personal watercrafts. Our alternators are designed to exact OEM specifications set by marine engine manufacturers, so they will fit and perform as well as the original alternator that came with your boat. You’ll find quality aftermarket alternators for nearly every make and model of marine engine. Boat owners give DB Electrical alternators high ratings for exact fitment, reliable performance and long service life. DB Electrical alternators also offer exceptional value and can typically be purchased below retail pricing of OEM alternators sold by boat and marine engine manufacturers, dealerships and distributors.
