Can anyone tell me conclusively if a Merc outboard flywheel has the part number 261-9007-c2 stamped into the steel on the top or bottom of the flywheel it is compatible with another flywheel with the same stamp? It seems that Merc has many part numbers for their flywheel depending on which model of motor that it is used on..Mariner also has this number stamped on flywheels of different horsepower and they use their own set of part numbers. I would be concerned with the size/thread of the hole as well as the strength of the magnets.

Thanks in advance.

Update: My motor is a '89 Merc 115 hp (4 cyl non-tower-of-power). The flywheel I would like to buy is from a Mariner 60 HP motor. Again, they both have the exact same number stamped onto the steel portion of the flywheel. This is an Ebay item so I want to be as certain be as possible before I buy.

I ordered/received the flywheel for the Mariner 60 HP that has the same 261-9007-c2 stamped on it. It looks the same as mine but before I installed it I tried to match up the teeth on the two flywheels. From what I can tell, the teeth line up for about 1/2 of the flywheel then they seem to be off a little. The diameter might be slightly smaller on the 60 hp one, but it is close. Does anyone know if these two parts would be interchangeable?

Based on the difference in diameter of the hole for the crank shaft, it looks like the flywheel I received is the wrong part for my motor. I can now conclusively say that even if the same part number is stamped on the body of two flywheels, they might not be for the same Merc motors. Following is some additional info I found on another site pertaining to part numbers for the '89 Merc 115 - maybe it will help someone else.
