LaCannes is a great company!! Only reason I didn't go with them was due to stopping in at Hallberg where I purchased my previous boat from. They were only $20 off of what LaCannes offered, so I went back there.
at 5500 rpms, you are right in the meat of the engine's wide open throttle range, but it is usually recommended to get that motor up to 5900 or 6000 rpm. To do this, you have a few options: 1) lower the pitch of your prop by 2 inches. This will increase your RPM by around 350 to 400 or so, and it will help your boat get up on plane much quicker than what you are getting currently. I would recommend going to a steel prop as well, since that particular motor has enough "umph" that an aluminum prop would flex a bit too much if you punch it. 2) if you are running steel already and the prop is not vented (holes in the hub), you could have that done, which would allow some exhaust gasses escape and hit the prop blades to allow the motor to rev up higher before the blades catch water. This will increase your hole shot, but there is a trade off with doing so. In larger waves, you may find staying on plane is harder to do because the prop will slip a bit more.
If you want overall good handling, decent speed, and good hole shot, the lower pitched prop would fit best. I would probably recommend a Michigan Ballistic prop that is either 1 or 2 inches lower in pitch than the equivalent aluminum. You may even find the same pitch in a ballistic will give you more RPM as well (at least that is what happened with my 90hp)
With enough tweeking, I bet that rig will gain some speed as well.
If you purchased from LaCannes, how close are you to Hastings?
