Balmar Alternators & Accessories
for Marine Engines

The Right Alternator for your Marine Engine

We carry a large stock of V-Belt & Serpentine Pulleys to customize the alternator to your belt type and size.

Trans Atlantic Diesels offers Balmar marine alternators in a wide range of styles and outputs at discounted prices.

Balmar marine alternators are designed with a unique construction and exhibit features that set them apart from the average OEM or aftermarket alternator.

Custom-wound rotor/stator combinations
Higher-amperage diodes
Larger sealed bearings
Corrosion resistant powder coat finishes

All of the above features enable Balmar alternators to excel where lesser alternators fail.

TAD strongly recommends, before contacting us about your Balmar Alternator purchase, that you download the Balmar Product Guide. The guide includes critical information that will help you to decide which alternator model is right for you.

Our customers are usually looking to buy an alternator for two reasons:

1) Direct replacement: You need a direct replacement for a factory-installed automotive-type OEM alternator.

2) Upgrade to your charging system: You want to replace your automobile-style alternator with a larger, higher-capacity alternator so you can charge more batteries, charge larger batteries or bring them up to charge more rapidly.

What to consider before you buy...

Before you invest in a high-output charging system, save yourself a lot of trouble and money by ensuring that you buy the correct system for your application. Charging systems vary by type of boat, and a long list of other variables including engine type, engine room space, belt type and size, battery bank size and battery chemistry.
