What prop do I have???

[Part-time]

I recently got a 16' J-Craft with a 1990 Johnson 100GT.
The aluminum prop doesn't look OEM. It has a curved edge to it, kinda looks like it has more pitch at the end of the blades.
There are two sets of numbers stamped on it.
71677 and OP136291.
It's a three blade and looks to be close to 13" dia.

The ice is starting to form on the riverbanks here but we gave her a quik whirl anyhow and got 56mph out of her on the GPS.

Re: What prop do I have???

It appears to be a SST OMC prop. To tell what prop you have on OMC props pull the prop and turn it over, Stamped on the barrel right at the hub it will have the numbers stamped in it.
