Yamaha serial number

Does anybody know if the small sticker on the top of the engine near the starter is the engine serial number, part of the sticker on the bracket is missing on mine?

It's a 100hp four stroke Yamaha.

The serial number is stamped into the head somewhere (google will tell you).

Ok thanks.

No it isn’t. That sticker is your serial number minus the prefix.

Yes google seems to suggest that's what it is too. Thanks for the advice.

Yup, that sticker is the serial number. Those F100 engine plate numbers seem to fade or disintegrate early. I had to use that sticker to get my engine insured a few years ago but I verified it with a dealer before quoting it to the insurers. I think the block does have the serial number stamped on it but it’s normally effectively inaccessible. I seem to recall seeing it behind the inlet manifolds when I had the carbs off or maybe behind the regulator/ rectifier and it did match the black sticker. The block is from the FJ1200 bike engine which is why the serial stamp winds up being inaccessible.

Thanks for the advice, not sure about being based on a FJ 1200 though as the outboard is a 1600cc engine. I had a Suzuki 60 once that was based on a 1300cc Suzuki car.

Also I've got to take the carbs off (again) so I'll look and see if there's any number there.

FJ1200??.!!, ever sienna an FJ1200 engine, because it’s nothing like an f80/100

It’s actuall based on Ford Zetec SE which Yamaha designed in conjunction with Ford.
