I have a 2015 200 HO, model #E200DHXABB. I purchased the boat and motor last year, motor had 62 hours. Motor ran great 5800/6000 WOT running approximately 52mph. (On GPS). As of recent still running 5800/6000 WOT but has lost speed to 42mph. 3 blade 14 1/4" x 17p prop. Haven't changed a thing.

Any ideas?

If the engine is turning the same rpm with the same prop, but the speed drops 10 mph, then something has changed. Check the accuracy of the instruments, have a prop shop check the blades, make sure there isn't new bottom paint or fittings added to the hull or transom, and check if any additional weight has been added to the boat in any way.  Do not overlook the possibility of excessive slippage due to turbulent or aerated water getting into the propeller blades.

Just like a doctor diagnosing a patient, you have to rule out one thing after another.

You do not have to post the same question multiple times here on this website. It is not needed plus it adds confusion at times. Please delete your other queries. Thank you.

Could the prop hub be slipping?
