Transom ID-plate missing, Mercury

[takrafft]

Hello
We have just purchased a boat, but we are in doubt regarding the motor. We where told it was a -87 200 Black Max. The ID-Tag is not on the transom plate and the whole engine has been repainted and is without any stickers... However, there is a metal disc embedded in the head of the block with the number 129599. Can someone aide us in identifying what model and size this is, please?

You should find a letter in front of those numbers...

If it's an 'A' then it's a 1985, 200hp.
If it's a 'B' then it's a 1986, 150XR2.

See if you can find the numbers on the carbs... They'll look like WH-40 or something similar...

Chris.....

200s used WH-14, 16, 18, 20, 28, 39, 46
150s used WH-40, 35, 38, 32

Something else ta look for.

There is also a "build" date stamped on tha block. It will be at tha bottom of no. 2 clyinder on tha block half right where tha motor parts split. Kinda behind tha advance timing arm. Small 1/4" numbers. Might be hard ta read. Will be m/d/yr.

Hi

I found the letter A in front of the number, meaning it is a -85 200 hp. That was a bit disappointing since we thought it was a -87.
But it is a cool, strong, noisy motor anyway....

My experience is that sellers rarely tell the truth, even if they know it....

1987 may have been when it was last serviced...

Well it certanly looks like that...
The oil injection system with tanks, hoses, alarms etc has all been removed! but it is running strong on a 2% oil mix with a 23 pitch ss propellar, pushing a -77 19 feet BW Outrage almost 40 nautical miles/hour
Any experiences good/bad with this motor?

Achris; I have been looking in various lists and tables but I can't find where this number shows it is -85? (or any other years for that matter...) Can you please link me to a good source?

According to this site: http://www.maxrules.com/Merc_model_files/172-300.html it looks like it is a -85 300..........

Re: Transom ID-plate missing, Mercury

Put in your serial number (0A129599), that gets me your model number (1200725) and that tells me, 1=Mercury, 200=horsepower and 725=year code. Keep checking years until the model matches up.... (I usually get pretty close as I know the approximate years of the various serial number prefixes)

This is not a web based program....sorry....

"According to our records, the engine with serial number 0A129599 is a 200 HP, model year 1986."

They answered very quickly!!
