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.

 

A high-output, marine alternators will ensure more electricity is available when you’re away from the dock, which gives you more power for electronics, lighting, windlass, AC appliances, marine water makers and refrigeration.

The Cruiser alternator provides 99% plug and play capabilities when combined with our E-MAAX external smart regulator, minimizes rewiring and ensures you’ll be charging your batteries at the most efficient level possible.

All Electromaax Cruiser, High Output Marine Alternators are 99% plug and play when combined with our E-MAAX external smart regulator, which minimizes rewiring and ensures you’re now charging at the most efficient level possible.

 

The cruiser compliments solar and wind power enough on small vessels and eliminates the need for back up gas gensets. The Cruiser range comes in five mounts, saddle 3.25″ (yanmar) 2.3/8″ 1″ and 2″ foot, plus the popular pad mount.

 

The smallest creates 54AMPS at idle (80AMP) and tops out at 80AMP. There are also 100,120,140 and 160 AMP versions.

 

We also suggest you convert your engine to multi groove (serpentine) which will allow amperages in excess of 100 AMP, eliminate belt dust, and quite down your engine.

 

The cruiser line is designed for the recreational cruiser; it is a small case – 100 to 160 Amp which is an ideal option for replacing your original manufactured alternator.

 

Our cruiser 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 water makers and refrigeration.

The Cruiser 100-160 amp 12v foot mount alternator comes in 100, 140, and 160 amps, for Volvo, Westerbeke, Universal or any engine with a 1 inch or 2 inch spindle style alternator mount. The Cruiser 100-160 amp saddle mount marine alternators fit to the Yanmar 3.15 inch mounting style engines.

 

The 100-160 amp Cruiser series provides excellent high-output charging performance. It’s perfect for weekend, or a week-long cruise. The Cruiser will deliver high amps at a idle, and even more amps at a cruising RPM.

 

The 100 amp alternator can be driven by a minimum 1/2 inch single V-belt (we recommend using a cogged V-belt like Dayco’s “Top Cog” for better power transfer) and can be driven with our comprehensive line of serpentine belt upgrade kits.

 

We recommend our multi-stage E-Maax voltage regulator to control these alternators, with the internal regulator kept disconnected as a back-up.

 

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.

Our 100-amp Cruiser-Series marine alternator is an excellent entry into truly high-output charging performance. Perfect for weekend, or a week-long cruise, the 100A Cruiser will deliver 70 amps at a high idle, and 100+ amps at cruise RPM. This alternator can be driven by a minimum 1/2” single V-belt (we recommend using a cogged V-belt like Dayco’s “Top Cog” for better power transfer).

Our most popular alternator model, the 140-amp Cruiser-Series marine alternator is a superior choice for applications with 500 to 600 amp hours of house battery capacity and 6 or 10 groove serpentine or dual 1/2” V-belts. This alternator delivers up to 115 amps while on the hook and exceeds its rating at cruising rpm.

 

To protect and extend the life of your batteries, this alternator should always be used in conjunction with a smart, multi-stage regulator like our E-MAAX charge controller. Due to its compact size to massive output, the 140 Amp Cruiser is a perfect solution in environments where a separate generator or large-case alternator are not possible. Includes internal two-stage regulator, and can also be used with other external voltage regulators. For use on engines with a 3.15” saddle-style mount.

Our most powerful Cruiser-Series marine alternator, the 160 Amp Cruiser is compatible with dual 1/2” V-belts or systems with our Serpentine Pulley Kits installed. The 160 Amp Cruiser is often used as a second-position alternator that’s dedicated to charging extra large house battery loads, or in applications where thruster and windlass battery banks require high-amperage replenishment in the quickest time possible.

Which Cruiser Alternator Is Right For You?

Your boat engine will determine the mounting style – either a foot-mount or saddle-mount. The horse-power of your engine will determine the specific alternator output (amperage) that’s required.

 

Combining Your Alternator with the E-MAAX PRO

Combining your new alternator with an E-MAAX 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.
