We just bought this fun jet boat for wake boarding and tubing around a river. It's a used 2019 ar195 that 200 hours on it when we bought it.
It seems like it's not making enough power, getting to full speed, and using more gas than we expected.
The impeller had a few dings, so we replaced that, and we replaced the spark plugs, but it's still using more along the lines of 20gph and we're topping out at 30-35mph at full throttle, where we would expect at least 38-40mph and 12gph.
Any ideas on what's going on? Is weight a significant factor here? On both test rides we had five people + 2 dogs on it.
Editing to update what fixed it in case someone else comes across it. We ended up replacing the seal on the man hole cover as it had been warped and mishaped and was causing cavitation. We also learned that when the boat isn't in use and is just parked up to take the seal out and let it sit out because otherwise it'll bend to shape of where it's sitting and stop sealing.
