    Water pressure ? 225 Opti

    What should the water pressure be at WOT on a 225 Opti? Gonna try raising my jack-plate and want to make sure I keep enough water pressure.

    The "book" specifications (minimums) are:

    -At idle: 1-3 psi
    -At WOT: 15 psi (prefer to see 18+ psi for safe measure in turns)
