I Have 33 Avance With Tripple 250 Mercs I'm Turning 25 Mirage Plus . What Would Give Me More Top End .
Tried 26 Bravos It Slowed Down.
My Next Thing Is To Lab The 25 Mirages. Will This Give Me 300 Rpms Each Motor Or When You Combine With Tripples You Get 400 Rpm Per Motor.
Option 2
Lab To The Max Rpm And Go Up One Pitch.

Ortion 3
Lab To Max Rpm And 1 Pitch And Raise All Three Motors One Notch.
Or Only Raise Outside Motors.

When I Raised My Outside Motors Last Summer My Ride Go Really Ugly The Boat Would Teder Totter Back And Forth This Why I'm Thing About Raising All Three...
Option 4
Get Three 300 Xs And Sell My 250 .. Try For 80

Opion Are Welcomed

Where Trying To Hit 75

More HP is always the easiest most expensive route to more speed.

Playing with engine height should be done before final propping is acomplished to determine the boat stability and ride attitude you find to be the best. This will also affect rpm levels and slip of any given prop.

Speaking of rpm, we need to know where you are at WOT (wide open throttle) to determine the best Labbing recipe and pitch to work with.

neutral trim about 5300 rpm full trimmed 5800 out side and 5700 center motor. this trimmed very aggressive.
i rather get the most rpms out of labbing so if there rooom for little pitch that would be great,..
thanks

Sorry for the delay,

At this point, Labbed 27 M+ looks like the fastest props for the boat.

i got the 300xs i willl be rerigging this weekend
