prop selection - E150EXEOM , 18' Outrage

[Beaux]

Current setup on my "new to me" fishing rig. <br /><br />1989 boston whaler 18 outrage<br />1995 E150EXEOM<br />3 Blade 14 1/2 X 19 SS prop <br /><br />She is used solely for saltwater fishing usually running out in a 1-3 ft chop to fishing areas with only enough speed to stay on plane but not much more (2800rpm- 23mph) . I'm not interested in highest performance concerning speed. My concerns are as follows:<br /><br />Current use usually involves three full size men, gear, and full 62 gallons of fuel on board. In this config, she will top out at 42mph (gps) and only revs to 5000-5100 rpms on the tach at WOT. I am concerned that this setup is straining the Motor/lower to much. Is that realistic? <br /><br />The current prop has a few dings in the leading edge that need work, but I am thinking of just buying a new prop which is more appropriate for this boat to get to the recommended rpm range. I could just keep the old one as a spare and not spend the $$$ for prop refinishing. <br /><br />Would a four bladed prop be more appropriate for my type uses and demands? If so, what is recommended for my setup? If three bladed, then I would appreciate a recommendation for this. I realize there is not a holy grail prop for me, especially with the limited info I have given... I am just looking for expert opinions to get me started. Any and all help is appreciated gentlemen. <br /><br /><br />Note-It has been a while since I have been on the site, so if I need to supply more info for a suggestion.. please let me know. It IS GOOD TO BE BACK IN THE BOAT WORLD <br />-Beaux

do we know the tach is accurate??? 19P sounds a bit much with that type load, but I would have "guessed" a bit more on the RPM.<br />what Make/model is the prop and where is the AV plate in relation to boat bottom?

Sorry for the late reply.
I do not know make/model of the prop. The tach is new to the boat and is teleflex make. I do not own a shop tach to confirm its accuracy.

One of my concerns was about the AV plate depth in the water when on plane.

I took the following pics with the camera as close to being on the same plane with the keel as possible. I also took a picture of the mount slots on the transom. I have never raised a large motor.

edit- I can't see the pics, so I will assume no one else can.:% The a/v plate appears to be 3/4 of an inch lower than the hull. The mounting bolts are located in the top of the slots in the motor bracket. This appears like it would allow for raising the motor up without having to add a jack plate. Although I can't see the top mounting bolts on the bracket as it is covered by a plastic cap.
