Question about a Yamaha SHO

I have a 2023 Yamaha SHO 250 and I am concerned the lack of stream pressure on the "overboard discharge" from the water pump. I have probably less than 6 hrs on the motor so far. When I am idling the stream pressure is close to average but not what I would expect. When am doing the break-in in the different RPM zones, the stream pressure drops off badly. An extremely weak stream. Like it has a bad prostrate.
My question to you SHO owners: is the water pump output variable? Does yours do this? I am afraid I picked up some form of trash in the intake and it isn't flowing the way it should.

Mines a ‘17 model and it does the same. At idle it’s only about 2psi and wot it’s about 11-12

I think mine is doing the opposite. Almost good pressure at idle and next to none at higher RPMs.

My 2019 250 is about the same.

So is my 2014!

To be sure I understand what ya'll are saying, is your stream stronger at idle,or stronger at WOT?

Mine is stronger at idle almost nothing at higher RPMs.

WOT

12 psi is all that is required for SHO's
