Prop finder

[Tenntrapper]

In my quest to get the best performance from my jon, I've been looking at props. My boat currently has a 11.25 pitch prop. I got on a "prop finder" and entered my motor info. It ask about boat length, type, layout, and such. It ask for weight of boat and motor, I entered 400 lbs.(the weight of just boat and motor), it said I needed a 15" prop. I changed it to 600 lb to account for trolling motor, battery, and fuel cell. It said I needed a 13" prop. I was already considering the 13", so I guess my question is...do you trust these "prop finders" to be accurate.. trustworthy?
