G'Morning, Irish.

Big!!!!

I have an 18-10 for my OS 1.60 two stroke.. that prop you mentioned seems a tad small for that big torque maker.

CGr.
Actually the OS 1.60 2C is more powerful than the Mag 1.80 4C, so the Magnum does use a proportionately smaller prop.

16x8 is right in the middle of it's operating range.

I have a 18x6 on mine, for my Giant UCD.
