Re: stratos 201 pro prop
First thing I notice is the diameter seems small. I've seen 24" props for 200 Johnsonsthat were 15 1/4",
I did find about 3 props that were under 14" out of a total listing of probably 80 props.
I think the prop should be at least 14" Its possible your prop isn't even intended for your motor.
Is the prop in excellent condition?
Check the motor height.Usually the antivent plate (just above the prop) should be even with or slightly above the bottom.
Is the bottorm clean and smooth, nothing mounted that might disturb the water near the prop?
