where was peak HP?
I'd think you'd wanna be easily cruising round 4000rpm.

peak HP was at 5500 RPM...........

If Im at 3000 RPM and 40 MPH, Could I be cruising at 55 at 4000 RPM ? That would be sweet. Ive got a 28 Bravo 1 on it right now...............

i used to cruise at 50 @ 4000rpm.
so yea... i'd say you'd be around 53-55 @ 4k.
you need to run it more.
make a spread sheet of rpms/mph.
then talk to throttle up.

Ok, went out yesterday afternoon, 4000 rpm...........58-60 MPH. (depending on water conditions and current). With the wind and current, 60 MPH. 5000 RPM.......72MPH. Didnt want to kill it on the second day out so thats as far as I pushed it. Plus, there is alot of stuff floating in the river. My problem is going to be my cruising speed on the CT river. Everyone cruises at 40 to 45 MPH. The speed limit is 35 on the weekends. At cruising RPM, 4000, Im at 60MPH! To cruise at 45, Im luggin it at 2500 RPM. I think I need 2 Props. One for the ocean and 1 for the river.............

I hear you.
At 25mph, i'd be falling off plane.

Keep testing, can call Julie at throttle up w/ your issues.
They may be able to make a prop to solve them.

Just an update, been trying alot of different props on the boat. This weekend used a 28 Bravo 1 LH. Full tank of fuel and 4 people in the boat, we went 72 MPH. That is also in flat water on the river. The boat likes the extra weight of a full tank, it handles great with weight on board. Was having trouble with the hull " torque rolling " with a RH prop, so I tried the LH. Worked great. Im going to lab finish this prop and hopefully going to gain alittle RPM and speed !!!!!!!!!!!

Nice...Kreed, do you know what your "x" is set at? How far is your propshaft below the bottom of the boat?

I dont know what the x dim is. Ive never measured how far below the prop is. If you could give me some guide lines on how to make that measurement ,I would really be interested in checking the x min. Your not the first person that was concerned about this possible problem. Thanks in advance..........Kevin

Nice #, but I would still try a 3 blade, might get an extra few MPH.
