Can anyone help with prop selection for an Xpress H22 with 200SHO?

Recently purchased an Xpress H22 and finished the break in period this week. Went to go WOT and all I could get out of it was 47mph and 4600rpm. That’s GPS speed. One person and a full tank of gas and nothing else in the boat. It came with a power tech 23 degree 3 blade. I know from reading other threads and forums that the RPM I’m getting is not correct but I’m also very conflicted on which direction to go for a new prop so any help would be appreciated!

My guess would be the motor height is too low. I had a 22 with the 175 show and could touch 57 with a 3 blade powertec 19p I think and 54 with the 4 blade Solas 18p. It should be an absolute rocket ship with the 200 sho

Put a Mercury Tempest Plus in that rig, should fly. Maybe a 21P?
Here’s an idea of what you should be getting:

I have a hydraulic jack plate also and messed with height for a while so I don’t think it’s that.

I would call power tech and talk to them. They are very knowledgeable about props and what they should do. I don’t see any reason why the yammy shouldn’t spin the hell out of a 23p.
Might be a dumb question but you did trim the motor right?

I went through every combo of trim and height I could.

Was 4600 the highest rpm you saw or does it just stay at 4600 no matter where you are the Jack plate and motor trim?
Posted on 8/28/21 at 7:13 am to civiltiger07
4600 was the highest I saw. It would fluctuate between that and 4200 while adjusting trim and jack plate

My F250 will spin the hell out of a 3 blade 21P or 4 blade 19P….but didn’t like when I went up to a 23P. Seemed to be a big jump for my setup.

200 rpm per 1 degree of pitch is the ratio, drop down to 20p or 19p. Most of those tin boat are stern heavy, would find a merc 4 blade in 19p to try.

That 200 sho should spin the hell out of a 23p. The boat hardly weighs anything. Even dropping to a 19p,in theory you would only get another 800 rpms. That would put you at 5600 which is better but i think you need to be around 6k.

Don’t know much about center console boats but I have a 25P Mercury Tempest prop on a 175 ProXs and it will turn out 5600 rpms. Motor is on a 18’ 9” Triton bass boat. I do have a Jack plate and boat trimmed out with just me and half a tank of fuel will run 64.8 mph. A 200Sho should be able to turn a 25P prop no problem. But like I said I do t know much about center consoles and how they affect rpms and what not on a motor. Running that low of a pitch prop I would think it would have that motor screaming on the high end of rpms with one hell of a hole shot.

Prop Slip calculator indicates yours to be 18%. That is rather high.
I had a similar issue that I was never able to fully resolve.
A couple things that did help reduce slip:
Prop with less pitch
Eliminated an EZ Pump (live well) pick up from directly in front of the prop. I believe this device aerated the water in front of the prop, killing the props efficiency.

Search express groups on Facebook. I’m in a few boat brand groups and people are always talking about tweaking performance with props.

I recently bought the same set up you are speaking about and having the same issues. Were you able to have this issue fixed and if so what was it?

I have a 20ft and for some reason the pitch doesn't relate to a bass boat. Even though the hull is the same. Can't explain it but it's what I see. Drop to a 21P and different brand. Try to find a 4 blade trophy
