The wrap around is from a 70's motor and I know that the motor is from the 60's. Try oldmercs.com for parts.

Welcome aboard, Adrianelooo. Look for your serial number stamped where the red is below. And try iboats for your part needs first.

Judging by the horsehoe lower wrap around and the top cowling this motor is a 1966 model.

Thank You mates very much yes it is right number of year I did discover on the list from internet but I was not sure .
Now to find power cable for the engine will be much easier .
Is that wrap is original ? I did find one part from wrap on internet and color was blue not red which make me confused
Which one is right for that year 1966 ? ,1963-1972 red, 1973-? blue
I have to be sure mate

Yeah, SN says 1966. '66 SN range is 1870389-2097444. Looks like the wrap has been changed to a later model. I looked at the lower cowl and didn't see the red flame out of the prop decal, which I think is unique to '66. Cowling/wrap wise, my '66 is still virgin. No blue stripes and it does have the flaming prop on the lower cowl. Jeez, I sound so anal.

Any problems with your 500, Adrian?

Here is a pic of the 500 the day I brought her home, for comparison. I don't a good pic of the flame decal.
