Info on 1990 Yam 80hp

[<Hightower>]

I've just purchased a RIB with a 80hp Yamaha AETO Autolube serial #: 6HO L 454487. It seems that this engine is overpropped as it's only reving to 4200rpm and would like info on manufacturers Wide Open Throttle RPM, Max RPM, Final drive ratio and recommended prop sizes.

If anyone has a manual for this outboard I'd like to buy a copy.

Yamaha Motor Corp. USA didn't make a 80HP in 1990 the serial number looks like an Enduro Motor and We dont have any information for that Motor
