Md Mark has 250xs's, not 250 efi's. Big difference. My 36 has 275 verados and will run 58-63 depending on load. Sounds like you need to raise your motors up one and give that a try. Props sound close.

IMHO he has alot of knowledge with these boats and set-ups that was all I was saying he helped me with a 225efi set up on a 30', I hope you get your figured out.

What will the 36 run with 300s or does anyone have 350s yet?

I think Marylandmark had his 36 with 300 XS's up to 72 MPH. It was listed in his avatar info for a while.

Maryland Mark has a 32.

I had a 2003 36 with 250 EFI's. With stock 3 blade props best I saw on low fuel was 60. Normal load, wife and I with 1/2 tank of fuel 56-58mph was tops. I had the props labbed and that made a little difference but not much. I do remember running at 4000rpm and 40mph was my cruise.

With out seeing your boat, it's hull condition, the props and motors it's really hard to help on over the internet.

Otis,
I had a 2001 36 Concept with Johnson 250's spinning 22 4 blades and was 58MPH on GPS, with the same props but labbed I was right at 60MPH...

You might get a few more mph, but remember they are not built for speed. So look into coast before you start RD because it is expensive.I know I had the 36 with tripple 300xs and spent to much on trying to make it go faster.But great boats lots of fun.Just not the fastest CC around.

I have a 36 with twin 300 Merc Verado's and have 21 pitch 3 blade tempest blade props. The fastest the boat has run has been 67.8 on gps. I am going to try it again this year before I pull it out to see if it will do a little more. That was flatter conditions and min fuel two people. The boat will always hit 63 to 65 no problem even with a good load on the boat fuel and full water. Have the bigger trim tabs as well and they defiantly come into play. Wanted to put triples on the boat when I ordered it and did a lot of research on that application and it wasn't worth the extra coast of the motor for the couple of mph more you would get. Also handling would not be as good. My boat I cruise 45 to 50mph. The haul defiantly likes to go quicker in a 2 to five foot chop and rides great in that water as well!! A friend of mine has a 30 with twin 300 Verado's and he runs 80 on gps.
