What is the specified charging current output from a 1983 Evinrude 90-HP V4 two-stroke. I have seen some numbers varying from 6 to 12-amperes.

When I was looking for what creates this output, the stator, I saw that they range from 6 to 25 amperes.

Someone--Help me out. I have been looking for this specification for the longest time. I hope someone will have the specifications on this or the similar Johnson.

Thanks

steve

My book reads "Johnson and Evinrude motors through 1985 (that means earlier in this context) come with a 4,5, or 6 amp unregulated, or a 6, 10 15, or 35 amp regulated alternator charging system. The 35 amp is used with the 185-235 hp V6 motors. The 6, 10, 0r 15 amp systems are used with most V4-V6 models. Check your owners manual to determine the exact system rating on your motor." Not very helpful is it....?

I'd get my exact model number off the tag, and go to www.ishopmarine.com. Choose Parts Lists, then browse, then choose Evinrude, then the yr outboard, then the HP of the outboard, and finally select your exact model number. The parts list for the electrical system should call out which alternator you have. If your motor has power tilt and trim, look up the description of the voltage regulator. That should include the amp rating for the charging system in that description. BillS

Steve,

The first letter is an "E", it is just worn or you need to get a magnifying glass and the right light...

E = Evinrude
90 = HP
T = Tilt & Trim
L = Long Shaft
C = 8 (first digit of the year model)
T = 3 (second digit of the year model)
E = (where it was manufactured?)

So, you have an
Evinrude
90 HP
Tilt & Trim
Long Shaft
1983 Model
I am not sure where it was manufactured with the "E". The "B" is Belgium.

The last letter on the model number is not where it was manufactured but a production code.

Sometimes there are mid-year changes on a motor and the code is used to tell the parts person that there may be different styles of parts for the same year.

The 1983 90hp had 2 types of charging systems, 6 amp and 10 amp.

Power Trim factory equipped motors had a 10 amp stator and a separate regulator.

The plain 90 had a 6 amp unregulated charging system. Some engines may have had the accessory tilt-trim kit added, but the motor still may have the 6 amp system.

Thanks Seahorse...

I wasn't sure that's why I put the question mark after the last digit...
(where it was manufactured?) above...

I re checked the number again and it is an E90.....

it does have power tilt and trim. 10 amp it is.

thanks again
