Have a 93' 115hp outboard 90degree v4 johnson compression reads 280psi all cylinders plus or minus 4psi all cylinders. I have verified the guage with another guage. Boat is a 17 foot nitro. boat does 98 miles an hour, at 5800rpm. The boat reaches this speed in about1 second. I emty a 15 gallon tank in about 10 minutes. It has a 16x32 prop. Im scared, of this high speed how do i turn her back a little?<br /><br /><br />PS. JUST kidding just thought i would intraduce myself. To the forum. Hi everyone. This site is great. lol
