Cruiser High-Output Marine Alternators For Boats

Cruiser High-Output, Marine Alternator

Introducing the ElectroMaax Cruiser High-Output, Marine Alternators

Available in 100 amp, 140 amp and 160 amp.

Dollar for dollar, upgrading your sailboat or yacht's alternator will be the best energy enhancing project you can undertake on your vessel. Our high-output, marine alternators ensure more electricity is available when you're away from the dock, which gives you more power for electronics, lighting, windlass, AC appliances, marine watermakers and refrigeration.

Which Electromaax High-Output, Cruiser Alternator Is Right For You?

The engine you have in the boat will determine the mounting style (foot-mount/saddle-mount).

The horse-power of your engine will determine the specific alternator output (amperage) required.

Combining your new alternator with an EMaax Pro, which by changing the field determines the alternators output means on a 20 HP you could install our Cruiser 140 amp and dial it in at 80 amp when the propeller is engaged and at 140 amp when on the hook or when under sail. The Cruiser 140 generates 78 amps (1000 watts) at 888 (engine) R.P.M., 105 amps (1470 watts) at 1330 R.P.M., and 2000 watts flat out. This means the alternator provides dual service. It is both an alternator and a back up generator - crucial on small boats with limited space.

Marine Alternator and Marine Regulator Installation

Unmatched installation support

Upon purchase, an ElectroMaax technician will contact you prior to shipment to discuss your application, ensuring you get the right parts and the easiest possible installation. The easy to watch video guides you through the simple installation process step by step. If you do need help, ElectroMaax provides free telephone support, too.

Now that we offer simple bolt on serpentine pulley upgrade kits for 150 plus marine diesel engines, you can turn that engine into an efficient gen-set when on the hook, as the larger output Cruiser alternators add the load needed.

All Electromaax alternators are now simple “plug and play” setups which equate to zero rewiring needed on all Yanmar’s and most other engines. Combine them with any E-Maax smart exterior regulator and now your charing is at its most efficient possible.

Our high output marine alternators can produce up to four times the energy of your existing alternator, essential for any cruiser.

Combine any of our alternators with our enhanced “4 step progressive constant current battery charging profile” smart regulators that include both battery and alternator temp sensors as standard, with our serpentine pulley kits, and you now have the most productive and advanced electrical system available today.
