Throttle Body EFI, Ser. OF562552
This engine powers a 1995 Ski Sanger DLX20 that I bought end of 2016. After a lot of work chasing down a fuel delivery problem, the boat has been running great for the last few years. Today it was stumbling off idle when trying to pull up a slalom skier. Usually it jumps right up to 3,500 rpm and has no trouble pulling anybody up. I also tested acceleration with no load behind the boat and it did the same thing. WOT is usually 40mph, but today it was only 36 on a windless lake. I last changed the fuel lines in 2017. Time for replacement? I put in a new fuel filter at the beginning of the season. Today I'll try injector cleaner and check all the unions in the fuel system. Any other troubleshooting tips are most appreciated. Thanks!
