Gear ratio x pitch X rpm = theoretical speed with 0 slip
Most v bottoms will be in the 11 to 16 percent range . The lower the better your set up is . Cat hulls and light boats will be in the single digit slip numbers if set up right .
The best prop slip Calculator is on BAM marines website . They also have a speed calculator that if you put in the correct data is scary how close it gets to what you run . Google Bam marine prop slip calculator. Hope this helps
