    99 johnson 225 ho

    j225hpleen. recently installed a water pressure gauge. I'm reading 0psi at idle but getting 24-28psi WOT. wanted to raise my motor a tad higher as I'm 4" under the pad. wondering what a good psi for WOT or cruising would be. any help would be greatly appreciated.

    I’m bout 2.5 under pad
    get bout 30 ish psi wide open, bout 18ish psi around 30 to 45 mph
    Im in sweet spot for water pressure, if I raise motor lose water pressure at slower speeds, and I go slower than faster all time,
    same exact motor and year as you
    at idle get bout 6 psi
