I habe a 1990 s minn kota 37 lbs thrust 4 inch motor does anyone know which prop will fit. I bought a mkp7 the holes too small the mkp4 looks right but no one shows the size of the hole

Is there any way you can correctly drill out a perpendicular center hole to allow it to fit? Not seeing either the trolling motor or prop in question, I have no ideas what your looking for. Post a couple pictures so we can see what you are dealing with. Pictures always helps. JMHO

I would put its not letting me post pics the problem is its not fitting over the shaft where it bolts to the motor the prop has a pilot hole that looks like 3/8 inch the old prop looks like its 1/2 inch. I dont know if i can drill it out the hole without screwing it up i dont have a drill press

Measure the shaft diameter and then head to your local sporting goods or outdoor store and measure the hole in the various replacement props. If the motor has a model & serial number tag, that should help get the correct prop, Just because it's a MK prop does not mean it is the best prop for the motor. Those are usually optimized for each motor.
