With props turning in (decals indicate they should) I was able to get 65 with 2 people and half tank of fuel. Docking manners sucked though. Was turning about 4800-4900 rpms. Think I'll turn them back out. Might also get some 26 bravo ones.

Mine are turning in and docking SUCKS. On top of the props, the very low idle of the 6.2 MPI's don't produce enough power steering pressure to keep up with turning the wheel at idle for docking. Latham makes a kit to plumb in the second engine's power steering pump to increase the pressure but it's about $400 which seems a bit steep for something that should work to begin with.

I intend to get back in the water Friday and run again with the props in and then put the boat on the trailer and switch them back turning out and run under the same conditions and get the numbers. Ill post from there and see what y'all think.

I had the same issue with the latham steering this weekend. I tested the prop rotation and turning in I was at 3500 getting 41-42 mph and top end at 65 at 4900-5000. Turning out I got 42-43 at 3500 and same 65 top end. both were with two people and about 1/2 tank of fuel. turning out docked significantly smoother so that's my obvious preference. I was just hoping for more on the top number.

still getting a ton of blow out coming on plane. am really wanting to test a pair of 26 B1's. anyone interested in letting me borrow, please?

Adjust wanted to keep this thread in the rotation. I know it's only January but already getting excited about the upcoming season!

Hello jralston.
I run 26 Bravo 1. 95% if the time and 25 mirage plus when I want to go a bit faster.
Tge Bravo 1’s are much better cruising but I never had the planing issues others talk about when I run the mirage plus.

I definitely want to pick up a set of B1s. it probably doesnt help planing with my boat that we usually have at least 6 people on the boat.
