I have a 240 Merc on my 2000 Sea Doo Challenger and it works well, but when I am going slow through rivers, it constantly stalls. I tried changing the spark plugs. Doesn't matter if I go 40 mph for 10 minutes first. Everytime I slow down, it stalls every 20 or 50 ft. Any ideas? I have not replaced the fuel filter. I did have the stater replaced last year. Would love some insight.
