Re: scout boats
Only 2 years late but just joined. My 162SF had same issues. After going through the major effort of taking off the console and the floor plate, found no anti-siphon valve. Finally found a repair shop that told me true. On the 162, since the engine is mounted sitting higher than the tank, Scout did not put these valves on that model. I have a 90 Johnson on mine and it turned out that a fuel inlet plate, part of the throttle body, had partially sealed on high speed side. This was located just before entering the carbs. After a major cleanout, it is just a great running rig.
