I'm replacing the stator on 89 90hp . The old style had faults so merc came out with a new part#398-832075A5 this new one is a 16amp I don't have the voltage regulator I have the regular rectiifier/regulator I'm guessing it is 9amp the instructions say to replace the voltage regulator and show a picture of one not a rectifier so I'm confused do I need to get a new rectifier?

Re: 3cyl red stator conversion

you dont need a rectifier, you need a regulator

Mercury knew there was a problem with the electrical system on the 1993 and 1994 90HP Sportjets. They made a CDM conversion kit that updated the electrics for those models in 1996,you should inquire if a kit is available to upgrade an 89 90hp.<br /><br />The Mercury part number is 835084A1 CDM CONV KIT-90J -List price $725.55 but can be found for $616.19 on the net<br /><br />The kit updates and replaces the entire electrical system and eliminates the problematic switchbox. The kit includes a new flywheel, red stator and trigger, voltage regulator, rev limiter, 3 coils and wires, wiring harness and more! You remove the old and the new bolts right on. The hardest part is pulling the flywheel. The new coils and voltage reg. eliminates the switchbox all together! It also boosts the output amperage so your battery charges better.<br /><br />The above info was posted by SeaRayder on another board.

Re: 3cyl red stator conversion

Keep an eye on your charging volts. I have 91' 50hp whose prior owner put in a red stator. I guess it was ok for quite a while, but when I bought the boat it blew the rectifier after a short time. For some reason, there was a seperate voltage regulator on only one of the yellow wires from the stator, and only the rectfier on the other. I replaced both with a combo rectifier/regulator.
