Our boat (19' Bowrider) has 42 PSI when hot at cruising speeds

Seems low to me.

Recently had dealer service.

120 hours

Alfa 1 leg

Used in fresh water

Is this normal?

P.S. did a search but nothing that I could find on this forum.

At least you have the smarts to watch your gauges! 40 psi sounds ok
