Yeah that definately seems on the low end. How much weight did you have in it? If you didn't have as much weight as you think you will normally run you definately have to get those rpm's up. I have a 2006 etec 250 on 23 Sceptre with a pilothouse up front and i'm getting 5800 exactly with 2 guys on the boat and 1/2 a tank of fuel using 17 pitch omc Viper prop. I always try to get the rpm's on the higher end when testing a prop so if i take on a heavy load it is still within spec and the motor isn't working so hard. If you are getting 5100 when you take on more weight if you do then that will go down to maybe 4800 or less.

I had two guys and 90 gallons of fuel not completely loaded up with gear or ice. I guess its something I'll have to look into. I do like the cruising speed I have at 3500 RPM though. Changing to match the higher end RPM"s is going to effect this right? PLus planing?

Always try to dial in a prop close to the weight your always going to have in it. For instance if you had a 19p prop and getting 5100 rpm's with the weight you had in it, then i would try a 17p to get that around 5300 to 5500. High pitch is going to give you more speed with less rpm's, but when you load the boat up that is going to make that motor work harder and you are going to lose fuel economy. Less pitch is going to raise your rpm's and give you a better whole shot when the boat is weighed down and make the motor work less. Once the boat is all weighed down you won't have that nice cruising speed you are talking about at 3500rpm's you will have to go down in pitch to get it back. Believe me we run charter business's with these boats so there is always alot of weight in them, and this really makes a difference.

At some point I'll start playing with props.
I've been dialing in the trailer a bit and tried to setup a keel roller. Well this is what happened..  Any ideas on different setups? I'm thinking I need forward bunks. I could adjust how deep I load and unload the boat but I don't think that'd be wise for wear and tear on the trailer.

That particular bunk placement must help line up the boat on the trailer really easy.

Yum Outrigger handles for dinner. Needed to shorten the handle an inch they hit my rocket launchers on the radar arch.

Perfect every time. I usually back the trailer up until the top of the fenders are level with the waterline, and then just drive the boat on.
