Ok so my 2003 Supra SS DD currently has a 4 blade prop. I think it may be the OJ 150 13*13 but I am not definite. Anyways, I have been told that the correct 3 blade version is more optimal for a Direct drive in terms of fuel efficiency, performance etc... I am running about 1100#'s ballast but will be moving that up to 15-1600 shortly. With current ballast at 20mph I am tachin around +3200 RPM and out of hole pull is fine. My question is if I go to a 3 blade version for my current ( or intended set up) will I still be happy with my hole shot. I would like to get my 20mph RPM down to <3000 for fuel saving and I would not mind more top end for Skiing / Cruising. I am considering the following: Acme 543 3bld 13*11.5 (.080 cup) OJ 150 3bld 13*12 (??? cup) I would be interested in your experience with these? will the .5 difference in pitch present a big difference between the Acme and OJ version? or do you think I should just stay with my 4 blade prop
