With a 95-amp output, this unit provides steady voltage for ignition, gauges, lighting, and common onboard accessories, while supporting faster battery recovery than lower-output models. It’s a strong match for boats running ballast pumps or upgraded audio without stepping up to a high-output system. Built with marine-duty components, it’s designed to handle heat, vibration, and moisture in real-world conditions.
This alternator features a serpentine pulley configuration and is intended for GM-based Indmar engines, making it a direct-fit solution for many popular towboats. It is commonly used on a wide range of Indmar-powered models, including:
-
Supra Launch 21 V, Supra Launch 22 SSV, and Supra Sunsport 22 V
-
Moomba Mobius LSV, Moomba Outback V, and Moomba Mobius XLV
-
Malibu Wakesetter VLX and Malibu Sunsetter LXI
-
MasterCraft X2 and MasterCraft XStar with Indmar engines
The 575014 is specifically designed for GM engine platforms, while Ford-based Indmar engines typically use a different part number.
Key Features:
- 95 amp output for reliable charging under typical load
- OEM-style Indmar replacement for correct fit and performance
- Serpentine pulley design for GM-based engine configurations
- Supports ballast systems, audio, lighting, and essential electronics
