So fixed the cavitation problem with new wear rings. Got the boat up to speed and then hammered the throttle. When I gave it full throttle, the right engine cut out, fired it back up and drove the boat for another 15 minutes or so and now won't run unless it's choked. Checked fuel filters and the fuel is incredibly dirty. Is it possible I sucked something up into the carb and clogged up a jet or something? I'm going to siphon the tank tomorrow and clean the filters again but i know I'm still going to be having problems with that engine. The other engine is acting up too but not nearly as severe. Thanks for any help!
