Re: Numbers on out drive

Thanks and it was supposed to be a 1.5 to 1 drive. Where is the drive ratio rpm chart link? Also, is there any easy way to calc the ratio off the boat besides pulling the cap? I do believe the props i have will not be much good for this ratio. i have 1 4 blade 245 and 2 3 blade 25 and a 3 blade 27:confused:

Re: Numbers on outdrive

I went to Bam and found the info i need for speed calcs. WOW.... 10% theoretical slip i should be able to kill myself rather easily....... 540 cid approx 675 hp and a 1.36 drive w/ 3400 lb boat and a 27 pitch..... even with the fudge factors it is over 100... In all reality i will be happy to break 90... :D
