Mercury identification by SN

[Eugenn]

I would like to know how many hp my engine has and in what year it was made . I kow only details from the plate serial 9217756 B4822 made in Belgium.

Welcome aboard.

Not finding a match on the serial number - Can you check it again?

To help ID the motor - How many cylinders and are there any decals on the cowling or midsection?

 

[Eugenn]

2 cylinders. The carburetor is tillotson

Where should i look to id it precisely ?

To get a very rough idea to start with, you can roughly judge the year by the style of logo. Look at the following photo. Which matches yours the closest?

EDIT: this miserable forum setup will not let me link to a picture not hosted here. Please just google "Mercury outboard year by decal" and you should find the picture I mean.

Looks like 1972

Is this a very small motor? Like something you could lift by yourself?

It looks like that belgium SN falls within the range of a Model 40, 4hp, also called a gnat. However, I do know that serial number ranges can overlap between different HP sizes. Does yours have a fuel tank right on the motor?

If I'm way off, posting a picture would help alot.

No fuel tank on top . Could be 7.5 or 9.8.

1973 7.5 HP

 

[Eugenn]

How do you determied it ?

Cross-referenced between Belgian, Canadian and American serial number ranges...started with 1972 but number range(s) were too low...fits in the 1973 7.5 HP range.
