Looking to swap out three Mercury 525's with bravo ITS sportmaster's spinning 5 blade 32" Herings hiting 95-96 mph with new 700sci's. Just wondering what speed's the triple 700's 43 ZR boys are hitting with NXT's as I'm thinking of going with bobtails.

Lucked out
Found the three 700 sci's we were looking for, now just trying to decide if we should swap out the bravo xr ITS's for the NXT's or take our channces and be quicker with no tranny's.

Boat has hit 119 but not me driving. The factory water test was at 118. I can hit 105’s without much trouble and boat is solid and comfortable. My son can bring it up to 119 with some effort and he is usually bouncing off the rev limiters so it seems that there is some HP left over. Engines are configured reverse triple. Stay away from the xr’s our formula tears them up with 600’s (with stelling extension boxes, so it might have a lot to do with the solid engine coupler).

Yes two in front center in back. I was initially very concerned about the setup, but the boat balances out very nicely. Also three gas tanks, main center 225 gallon and two 50 gallon side takes with a electric transfer.
Do you have mufflers? We don't and I am considering adding.

Two factory tanks, not sure but about 100 gallons each, yes on the mufflers, switchable teague 450's in the aft, mufflers in the side.They work great in the harbour.
Andy, what's the pitch on your props. I'm spinning port and center right and starboard left.

Same on the rotation. 17" x 38" for all three. The original setup had a 39 for the center but blew the bottom out of the drive and lost prop. Replaced it with a 38 because I was in a hurry and I couldn't get a confirmation on why the center was a higher pitch. Do your side exhausts switch mufflers or are they fixed? Are you going with new on the 700's? Great setup! But $$ ouch, expecially if you go with the NXT drive lines. Seems like you will have to rework the exhauste and the transom as well. You go by Rob? Were do you boat? Mine is primarily salt water use and I am struggling keeping up, especially in the engine cabinet below the air scoops.

Not sure just yet, engine swap out is staight forward, everything will be plug and play seeing how the 525,600 and 700's share all the same base componets, if we go with the NXT's or NXT 6's will deffinetly get a local to due but will have to find someone from the factory that performed rigging (if any are left) to send out info on x dimensinons, hardware required and propping.
