Can't find similar problem on any forum. Got it back from the shop and then couldn't take it out over winter due to circumstances. Finally in water and fired it up. Ran fine at the dock. Revved all the way up to about 5000rpm, sitting and tied to the dock and in gear. When I take it out on the lake, it refuses to get to WOT. Won't run faster than about 4000rpm. Tried cycling the throttle several times. Switched tanks to see if it was a pickup issue. No difference.
