Re: schatze

You sucked up a bunch of crud off the bottom of the tank. Hope the injectors are not clogged. As for the engine running faster out of the water than in the water, there is no resistance on the prop so an engine running on half its cylinders can still blow itself up if run wide open with no load. Stop doing that. Three shops eh? Better try a fourth - prefereably one that actually has factory trained techs.

Re: schatze

clean your vst filter was that cleaned ?.

if it had codes it would only turn to 3000 rpm and hit rev limiter so it is a fuel problem
