The Model 18-5953-1 Alternator Replacement Kit

A simple bolt-on solution to 470 Series MerCruiser charging problems

PROBLEM: Burnout

The Original Equipment uses a stator that puts out continuous current and heat, so its water-cooled voltage regulator is subject to burnout. And even with an expensive replacement, the problem won't stay fixed.

SOLUTION: Model 18-5953-1

This new conversion kit utilizes the alternator found on most other Mercruiser stern drives, which charges only when current is needed, producing less heat and less chance of burnout.

BIG PLUS! Efficiency!

The new system is more energy-efficient, resulting in more miles per gallon and higher top-end speed.

Includes new 68 AMP. Delco one-wire alternator

Serial Number 690228 & Up requires the installation of a 90 Amp Fuse Kit.
