Completely confused

[daddyone23]

I have a 2020 Action Craft with a Yamaha VZ 200, 2005 model.
Problem is I added a Bobs Jack Plate and a new Prop at the same time.
Only thing different with the prop is it has an M stamped on it and the old one did not.
It seems to slip or cavitates when I take off at full throttle. I know more information is needed, but do you think it’s the prop with an M, or the Jack plate. I don’t know where to start.
Thanks

Put the old prop back on and see what happens, mark the new prop and hub to see if it is slipping,and look to see if you have the motor up higher than before you put on jack plate

Ok Ill give that a shot, anyone know what the M stands for on the prop. Just curious

The "M" just means it's for a V6 gearcase.
