If you're still running that bow lifting Viper prop, that's one reason you can't plane below 3800 rpm, but they also changed the shape of the throttle cam on the early 150's to address throttle sensitivity complaints. However if you fit the Rev. C cam that Capt. Terry mentioned, it should also have those changes in it.
