Thanks for the advise.

The recommended range is 4500 to 5500. The engine makes max HP at 5000. I like to prop my boat just a few RPM higher than the Max hp otherwise I find that the few extra RPM's result in more fuel burn and very little additional speed as a result of a drop off in the torque curve. I have had good lock proping motors accordingly. I have a 2200v pathfinder with a 225 Yamaha OX66 I have i propped for a WOT RPM of 5200. (it is 4500-5500 as well) I have 900 and some odd hours without a glitch.

I am thinking about going with the 17, I just want to how she runs once she is broken in and fully loaded up. I will let you know.

Thanks
