I had a mercury 90hp for 7 years and didn’t have a water pressure gauge. I always watched the pee stream. Now I have a 250 proxs and it has a gauge.
I have a strong pee stream, but the pressure is around 2 at idle, and around 8psi while getting into it and running around 3,500 rpm’s.
Everywhere says this is low.
Is it time for a new water pump then?
