The speedo pickup removed was good for 2mph in my Talon. Getting my 325# friend out of the boat was good for another 3 mph. Love ya Sparky.

Hi!
In the world of outboards a jackplate does the trick. Jacking a engine up 5 inches easy translates to 6-8 mph depending on the hull. A jackplate is the best investment for us outboard heads who aim for speed

so my water preasure is pegged at 35+ at WOT as well. brings me to the next question which is, what is the correct water preasure at WOT and does it vary by engine builder and HP.

Consult your builder as it also depends on the type of cooling system the engine is using. Open vs. Closed cooled, extra coolers, etc.......

Power required goes up with the cube of the velocity. With the significant density of water and the speeds they were running I have no doubt that small obstructions in the water made for big drag.
30 mph you may not notice much. 100 mph you will.

Also depends on the head gaskets used as to how much danger you are in when being over pressure. No matter what, pegged or 35psi is too much.
