We offer genuine Tohatsu/Nissan 12V charging systems that include a voltage regulator (rectifer) to prevent overcharging of your battery:

ELECTRIC START MODELS: 12V CHARGING IS STANDARD
Electric start model engines automatically come standard with the 12V charging system pre-installed from the factory. No assembly is required. You simply connect the 8.2 ft positive/negative battery leads (provided) to your battery.

MANUAL START MODELS Optional 12V Charging System Cost:
4, 5, 6hp* = $179.99 w/Free Shipping (Service Manual: $29.99)
8, 9.8hp = $179.99 w/Free Shipping (Service Manual: $29.99)
15, 18hp = $129.99 w/Free Shipping (Service Manual: $29.99)

*6hp (25" ultra-long) sail-pro models include the 12V charging system pre-installed by the factory.

For manual start models, the add-on 12V charging system requires installation (electric start models include the system pre-installed). We recommend professional installation as the flywheel must be removed to install the charging coils. If you could not or did not wish to complete the installation yourself, any marine tech should be able to complete this service for 1 hour of labor. We can also install the system for you at a discounted fee of $45.00.
