Was there a notable difference compared to the 15 x14.25 prop?

Tross49, let me know if you find anything more out on this. I'm also interested on this mod but I'm concerned that the exhaust port on the transom is lower on the 2016's and it might be an issue.

What engine do you have? We have a 2016Ri237 with the H6 engine and the 15x14.25 prop seemed to be the best compromise at altitude. I'm curious to see what you think.

What is the most recent software release?

I was just going to say there has to be someone there from the forum that could get us some better pics. Congrats to the better half on the 2nd place! Do you think you could see what prop is on it? Also is that a rear camera I see?

Good catch CO Surfer. It almost seems like they are about 2ft further back, like the Ramfill tanks are the same size as the Ri237's.

I agree with you to a point but I think it has more to do with the inefficiency because of the steep shaft angle and the too small prop diameter. In our RI237 we typically surf with three people in the boat and one surfing. We don't fill the bow PNP which I believe weighs around 750 lbs and we run the non-surf side ram at 90% and everything else is full. And our surf RPM's are around 4200. When we ride in our friends G23, that has the same engine but better shaft angle and the prop diameter is correct for the transmission ratio, we fill all the tanks completely and have 9 people in the boat when 1 is surfing. The G23 surfs at about 3300-3400 RPM's. When you look at the backed off ballast weight on the RI compared to the full ballast and more passengers in the G23 the total weight is about the same if not heavier on the G23 but the RPM's are much lower.

What about being over 4000 RPM's while surfing?

Trying so hard to be patient....

I think that they are one of the only brands that isn't at Surf Expo this year...

It also seems like, from the picture above, they have backed themselves into a corner with the prop to trailer clearance now. It doesn't look like they have enough room to go from the 14.5" prop that is on the boat to the 16" that is needed and not hit the trailer prop guard. The prop guard can't go any lower to the ground so the boat would have to be raised slightly on the trailer but the Ri237 is already 11'6" on the trailer with the tower up and over 8'6" with the tower down.

Agreed. They only needed about 1" to 1 1/4" more to properly fit a 16" prop. But supposedly since they were already at a 16 degree strut their options were limited off the shelf and had to go with a 18 degree strut which was a big jump at the prop. You would think for what we are paying for these boats they could have gone with a custom angle strut.

The prop shaft angle on the 2016 Ri237 was already 16 degrees, I wonder what this new angle is. Supposedly going to a higher angle then that can cause a bunch of issues (lowers efficiently of the prop because of the angle, vibrations from loading and unloading of the prop, boat porpoising, etc...) What's interesting is that somehow Nautique has fit a 17" prop on the G23 with only about a 13 degree shaft angle.

What engine and altitude?

I hope all of those devices don't pull their power through that fuse and you are just loosing the device that controls them otherwise this is horribly unsafe for a few reasons. The ballast pumps alone would pull 48 amps (12 amps each x 4 pumps), so running all 4 pumps and anything else on that circuit could overload it. Also if only one pump shorted it would have to draw more than 50 amps to blow its breaker. I'm crossing my fingers that the breaker is just for a control module that switches power for those devices but I also haven't found the breakers/fuses for the pumps yet.
