Like it says in the title -
I used it out of curiosity, and granted my engine doesn't show up on their database, but picking a 2000 60Hp 2- stroke & a "Fish & ski" (closest combo I could get to my museum!
) it reckoned I needed a 15" x 10.25 dia.
Based on my run with a working tacho, I reckon I need a 14" based on my current 13"x10.25 & the fact the boat was about as light as it was going to get. (me + 1/2 full tanks). a 15" would park it right in the middle of the reccommended revs (I want to go top of the rev band as more weight (passengers etc) will slow it down a bit). I was surprised it was so close, so am now curious - did I just luck out?
So, this Q is more down to idle curiosity than anything else, but if you used it, what results did you get with which boat choice? (bearing in mind there is no "rib" option on the boat drop down...) and how close is the result to real life on your setup?
