Alright guys, I know it's not exactly a prop question but props are the closest category I could find. I need help with my jackplate setup. I have searched the forum and came up with how to initially setup a plate. Sounds simple if you have a water pressure gauge..... I do not! I want to play it safe and supply my engine with the cooling it needs but I also want to get the boat where it doesn't spray water on the starboard side of the cowling and porpoise like crazy at cruise speed. I had the engine really low in the water (too low I think) it would porpoise like crazy at 35-40 mph but fast speeds 60-65 it would smooth out. It would also spray water up on itself at any speed on the starboard side of the cowling. I lifted the jackplate up 1" bringing the centerline of the prop shaft 4.375" below the straight edge brought off the plane of the pad. This is a 2.5 mercury 200hp without a low water pickup turning a 25p laser II on a 18ft Astro fish and ski. As far as rpm's go, I already need more prop. With the motor dumped it still redlines before I get wide open without it trimmed out any. Am I closer to where I need to be? Thoughts, opinions, concerns? Thanks allot guys!
