So i could just change helm control and leave that way.. my drives have over 500 hrs possibly. I was hesitant to leave that way, but sounds like its shouldnt be issue.. will prop still wait till after this trip since we will be hauling over an hour way from home!! Thanks JT

That 496 has to be on the limiter to push that boat to 70,
pull your turbulators in the exhaust too. Will not hurt a thing,
and will help you get that last little bit of pull u need. I think someone
gained 5-8 horse on a dyno with em pulled a few years ago.

Spent a long weekend at LOTO this last week and had time to collect some data on the props and boat.
Local prop shop fixed some pretty good dings and cups that were flattened from original owner, props are back to stock with just a satin finish.
2007 35 Outlaw Twin 496 HO's B1 4 blade 26P, X drives, 1.50 ratio
Water condition-light chop maybe 6"
Time 9:00 am Sunday on LOTO so not a huge amount of boat wake
Air temp 81 degree low humidity
Water temp 70+ degree
1/4 tank of fuel (185 gal. max) 2 passengers 500 lbs. and 40 ponds or so of cooler
Time to plane 7-8 seconds - 3 different runs
Trim Tabs all up, boat doesn't seem to need them to correct port/starboard list but only way to hold 30 MPH or slightly slower and plane is tabs all down (rarely in this condition)
3000 RPM 35 MPH Trim 1-2
3500 RPM 44 MPH same
4000 RPM 53 MPH same
4500 RPM 63 MPH Trim 2 +
4800 RPM 67 MPH Trim 4 This was WOT for a solid 90 seconds I could trim up a bit more and gain some RPM but no speed increase
I think this boat/engine combo from other write ups would do 72 or so. I'm pretty happy as it stand but 70 MPH and 5000 RPM would be nice if I didn't have to give up a lot of the bottom end. I have a bblades test form filled out but going to wait till winter to send them in any suggestion though on what someone else with same type of boat has used would be appreciated.

If you take a grinder to the trailing edge of the blades you can add some cup back but it takes a steady hand to not f them up. you don't need to remove any material just need to make an edge that gives the trailing edge of the prop some cup. Look around at some other boats or at a new prop and you will see what I mean.

yes if you think about right now one drive is in reverse and the other in forward when the boat is moving forward you are just switching which drive is doing what won't hurt anything. I changed my props to spinning in and pick up a .2mpg which doesn't sound like much but it is almost 10%, minimal speed change but I only run 40 or 45 most of the time.

If you are interested in maximizing your cruise speed, and still maintaining great top end, please consider the P-5 X's. They will run as fast as Bravo I's and out cruise any 4 blade. When you lab the Bravo's and reduce cup to gain rpm, you will gain some top end, but lose even more cruise speed over the stock Bravo 4 blades.
