Re: ?year #s 5797770

Thats odd as the 50 3 cylinder came out in late 1983 starting at the these serial numbers: 6428681 THRU 0B122929
Remove the cowling and find the serial number disk on the starboard side to see if it matches number on midsection. If so it may be a 60 with a replaced cowling, same engines nothing different but high speed jetting...

2 x carbs = 4 cylinder motor.

That serial number is good for a 1979 50hp (500) 4 cyl.

just looked did not see a disk all i got was under the carb on the manifold was 961-5887 and then also on the starboard side where the plugs go in it was stamped 865-8361 and directly on the head where you install plugs was 1025-8363 i'm very very lost too( it only has #3 plugs and wires)

It should be a 4 cylinder engine, Because even the parts Description show a QTY of (4) for the ignition under your engine serial number.

part# (QTY) Description
99215A25 (4) LEAD ASSEMBLY, SPARK - PLUG Wire
63709A 1 (4) PROTECTOR ASSEMBLY - wire end
2854 (4) BOOT, IGNITION COIL - Wire end
97182 (4) SPARK PLUG (NGK #BUHW-2) BELGIUM AND CANADA USE ?33-75739! SPARK PLUG

MERCURY - (50 H.P. (1980))
Serial No: 05797770 Model No: 1050520

Re: ?year #s 5797770

By the serial number it would be a 3 cyl. 70HP engine built in 80/81 with a 50hp cowl on it.
