No less that 10 psi. It all depends on the height the motor is set at and the set back.

When I had my ProMax it would run around 20 psi @ WOT.

some are different
Jessie, I have had one that no mater what or where we ran the mtr it never showed more than 15. Changed water pump cked lines no luck. we decided it must be the gauge. however when we repowered the boat the new mtr would show up to 25-30.--same gauge.

12 to 15 is minimum. With this motor on my Blazer, I would get around 14-15lbs at wot. The same motor is now on my Ally and I get 20-25lbs. But the min is 12lbs.
