I was turning a 28 bravo to 6900 @ 93 mph and with the amount of beef (550#) and full fishing load, 10 - 15 gal gas, that worked out to 11% slip +/- (1.75 gears)

I can turn the same prop on 1.62 gears to 6550 at usually 95 to 97, I would think with the load it would have ran the same speed of 93.. (1.62 gears)

Also seems that I can go down to a worked 26 Bravo with 1.62's and get the same results as running a 28 Bravo with 1.75 (better then usual hole shot and higher rpm's if needed..

So where in this mess does turning a bigger pitched prop more rpm's equal more speed?? I have turned the 4 blade ET cut to 10X at 6200 which is right at the WOT range of my motor. So with the 1.75 gears and same prop will I just be turning more R's and doing the same speed?????? That is what it seems like.

Does seem like the 1.75 may be good for a summer lower unit

Just trying to figure this out, and will be running them again next weekend so I have to learn the motor trim combo all over again with the 1.75s
