Just recently purchased a 2019 ProXs 200 4s last week. Serial #2B597099
I am currently still in break in with 4.1 hours. This has the 1.75 TM lower unit. So far the motor is great and impressed with how smooth it is.
What is puzzling to me is how much smaller prop I am having to run to get the RPMs in the 6000 operating range. The older 2 stroke models are turning much larger 24-25 pitch props and a little more top end than what I am seeing. I know I am still in break in and maybe will loosen up a bit between 10-20 hours.
The boat, a 2019 Triton 18 TRX came with a 24 fury. What we saw during testing was around 5400-5500 RPM, way short of the 6200 RPM redline. We ended up dropping to a 22 Tempest Plus and this currently is around 5900-6000 RPM (vessel view) and 68-69 mph gps.
I have heard that the new lower units are more aerodynamic and efficient and that the V8s have more torque so it surprises me that they cannot turn a larger pitch prop to meet the optimal operating range than what we are seeing. Then again 200 horsepower is 200 horsepower either in 2s or 4s.
Thoughts?
