Hey Fellars,

Here's the jist....

1976 Evinrude 85HP

It came with the boat I obtained a few weeks back. Now the prop that's on it says 14x17. Does this sound right???

I tried using the prop finder thru iboats, and I get a range of sizes from 12 3/4" to 14".

The boat is a 1973 15'6" open bow Larson Shark 1550. I'm guessing a liitle over 1000lbs with motor, fuel and what not.

I'm not sure what top rpms are as I don't have a tach. According to the plate on the motor it's supposed to be 5000rpm.
