Slip ratio

[Hotboat]

Can someone help me find out what my slip ratio is on a couple of boats. (1) 18' Donzi Classic turning 5300 rpm, 59 mph, 22 pitch prop (2) Century V-drive turning 4400 rpm, 49 mph with 14 pitch prop. RickR, your good at this. I don't know the formula. Thanks

The Century is 1.00:1.00. No reduction. I am not sure what the ratio of the Merc 1 is. Should have asked Billy when he went thru it. Thanks

Hi Dale
If the Merc is at 1.50 ,5300rpm 22pitch speed 59.8mph. the slip should be 19
