Is this the right prop?

[maxe]

Hi guys I wrote awhile back about problems I was having with my 1991 Evinrude 175 Intruder. All problems have been fixed and it is running like a champ. Here is my question, the motor has a Stilletto prop on it. The numbers on it read 20422. In the Overton's catologue I believe it says it is a 22 pitch prop. I don't have a gps but my gauges say I am doing 68 mph at 5800 rpm.(WOT) Also my H2O gauge reads 10 psi at WOT. It doesn't get hot though and no overheat alarm sounds. The model # for this engine is E175GLEIS and the serial # is G02974793. Any advice would be appreciated. Thanks.
Oh I forgot to mention it is on a 1991 Bass Cat Sabre.

I think I would get the RPM's back around 5500, I don't have much knowledge of the Stilletto.

Okay, I'll back it down to 5500. So the water pressure is okay? Thanks again.

See if you can get the water pressure up to around 15 PSI.

What can I do to get my pressure up. When I'm on pad there is no rooster tail coming above the mid-section of the engine. It has a power lift jack plate so do I lower the motor til the pressure comes up? I bought this boat a couple of months ago and I don't know when the last impeller service was done. Could this be the reason for the low pressure? I don't want to mess with the set-up too much as it handles well as is.

Drop the motor a little and see if your pressure comes up.

You can always have that prop worked too, if you need more pitch, having a prop shop add some cup will drop your rpms, although you may see them drop when you lower the engine.

Mine was to high, I lost pressure when I turned and the engine was trimmed up, so I dropped it about an inch. No problems now, and I switched from a shooter to a raker, and even way up on the pad, which I never got with the shooter, I still have good pressure.

You don't want it low.

Thanks bro. I will lower it a bit to see if the pressure comes up. I am thinking of getting the prop worked on or a new one. I would think getting it worked on would save some money. haven't talked to anyone yet.
