Mercury 50 model identification

[Sailfishing]

Hello,

I was referred here from the ybw forums, as someone may be able to help.


I am trying to identify a motor I'm fixing. It does not have a name plate/serial number fitted.

It is a 50 hp, 2 stroke, 4 cylinder mercury.

The cowling is made up of a front plate marked Thunderbolt Ignition, a wrap around band and a top plate.

It has CDI ignition.

It has 2 carbs fitted with MERCARB cast on the float chamber, they have integral fuel pumps.

If anybody could advise the years these were in production it would be great. The reason is I wish to get a service book for it.

I do have the cylmers Mariner 2-220HP 1976 - 1989 which covers the Mariner 50 (pre 1985, 4 cyl)) which from the descriptions in the book is very similar.

Does anybody know if this engine identical to the Mercury? Allowing me to use the Clymers I have as a guide (tune up settings?).

If not does anybody know what years different engines were in production for, to allow me to order a mercury shop manual...


Any help would be gretfully received...

Regards,

Kev
