Speed, RPM and SYNC

[JK230SP]

Last post for today.

There was another thread that mentioned expected top speed and associated RPM.

The other day I took a picture when running near full throttle simply because it felt so good to have nearly 100% of the speed designed into the boat while the RPM / motors were in Sync. Something very satisfying about driving a smooth operating boat at top speed....even though it is nine years old. I have 118 hours on the starboard and around 40 hours on the port engine (replaced by dealer two seasons ago after a supercharger failure immediately after they overhauled it). In the picture I am seeing around 52 MPH into a fairly strong headwind with the motors running at 7600 RPM. This is a 2012 230 SP with twin 215hp Rotax. I think I had at least 1/2 tank of fuel, as I have often hit around 54mph with no wind.

I have the same boat. Is that a RAM mount on the left of your console? I am trying to find a spot to mount a GPS.

Yes it is. Here is the view from two angles

Thanks JK! Is your orange/white vinyl original? It looks sharp. So you run your tunes on your phone and your nav on the Helix 7. Definitely ship-shape.

I bought her in 2018 with only 25 hours on the motors. I waited for the SeaDek sale pm Jet Boat Pilot in 2019 and got rid of the factory carpets. Then I noticed that people started talking about having trouble buying replacement cushions online. I replaced pretty much every one over the next year as I could find available cushions and decent pricing. Leaders RPM was probably the source with the most. I did not replace the captain's chairs, however. None of my cushions were torn, but once I discovered how much firmer the new ones were, I thought it would be a good investment to replace them before the stock was gone...
