Going from 6 cyl 225's to 4 cyl 4 stroke 200's did require a prop change.. went to 14.5 x15 4 blades . For prop nuts, using 15x 18 4400 RPM (wot) , 14.5 x 15 5600 (wot) 4 bangers just don't want to swing a 15" dia prop. fuel savings ( Vs- ox66's) is very notable! ($100...

I just repowered from 225 Ox 66's to F200's. The OX66's were definitely gas hogs! I went out with a friend that has same boat as I (272) he had 200 hpdi's and he burnt @ 40% less fuel! (he has 19" yamaha props) ( different water conditions also) . I only have 2.6 hrs on my new...

272, twin 225 ox66's-- On almost flat water with my 15.25 x 18 4 blade props, running 3600rpm, I am running just over 30mph Wish I had fuel burn meter.

I do not have flow scan, (or don't know how to get it to show) only 3 guages.. if that tells you anything. I don't write down numbers like I should either-- but I figure" it is what it is".. ( I will spend what it cost to fish) I ran out to ocean yesterday, overall ran 40 miles further away...

I wrote down few numbers while out fishing yesterday , The low RPM and mid RPM were showing Very low slip! to the point I was wondering if they were wrong,, But ran them again and again.. must have been right! The WOT was 5100 and 41/42 MPH which was about 14% slip-- which is AWESOME for...

Figured I post my findings and maybe help others looking for prop info On grady 272's I contacted several places and people , The Best info said 15.25 X 17. Since I was currently running 3 blade 21's, 17 seemed a pretty good drop , so I installed some 4 blade 15.25x 18's Yesterday. Water...

never did see Prop size posted, On my 272 sailfish 225 ox66, I have Yamaha (14.25?) 21" props .. I assume it came set up that way boat does drop off plane @ 24/25 mph , wondering if a 4 blade 20" would help keep it up on plane on rougher days when you can't run higher speed? Or if that...
