I have been in these boats with both engines. The 450 does great. The XS550 is awesome though. It sounds like an airplane taking off, and has crazy power.

So, the 450 is plenty and the 550 is just icing on the cake. Top speed isn't all that important to me, but what kind of speeds did you see with these engines? And was the supercharger whine annoying on the 550?

XS550 ... and yes my dealer is saying not until September. I am up in Canada however, so would take time to ship. September is not a bad month for being on the water tho, usually a lot nicer than July, it will just suck to lose out on all of August.

Which engine did you go with?

I spec'ed it out with the ZR450, but I'm seriously thinking about the XS550. That engine has to be a monster!

Which engine did you go with? I talked to a dealer and it looks like they are slated for August. I'm debating whether or not to just wait and order one so it will arrive in March.

I am in the process ... going to finalize order next weekend, however due to demand looks like I wont be boating until September ... Worth the wait I think though.

Jd already has one. Not sure which color/engine though

Pulling it behind my Duramax, no problem

I'd love to retrofit a Duramax in my Yukon.

Picture that - a Silver Birch Yukon Duramax sleeper pulling a G23 silver cloud/onyx black with black tandom trailer dual disc brakes.

Has anyone on here ordered one yet?

page 56 of the 2010 PCM manual under Engine Specifications advises that the maximum cruise RPM for a 5.0L is 3800 rpm, and the 5.7L and above is 4000 rpm. nowhere does it reference "blade angles," or pitch, which by definition is the displacement a propeller makes in a complete spin of 360° degrees. blade angle, which varies along the blade length, along with cup, diameter and blade shape all contribute to pitch.

Okay but the cruising speed of a boat depends on pitch and rotational speed of the prop. A boat with a speed prop will go faster than one with a power prop which is built more for pulling torque...

Just curious if the cruising speed of the G23 with the XS550 will be similar to the 230?

Yes, but also depends on the prop blade angles ....

max sustained cruise speed per PCM's guidelines is at 4k rpm. to that end, i am sure it will cruise at 4k rpm just like any boat should, hahaha....

What do you think the MAX speed of the G23 will be with the XS550? Will it get up and cruise like a nautique should when the ballast is empty?

I'm sorry I was thinking of my boats engine. I do have the 5.3l with 3.73 gearing tow package. I just got home from towing my 210 on a tandem trailer with half a tank in the boat and I barely notice it. I would want some awesome trailer discs too.
