    Slx 780 Cutting Out At High Speeds

    Just New Into This Site Just Resently Purchased 1996 780 Slx Polaris Watercraft And New Engine Only Has 12 Hours On It But When I Reach A Constant Speed It Seems Like The Power Is Being Shut Off For A Split Second And Then The Power Kicks In Again. The Pwc Seems To Have All Kinds Of Power And The Sparks Plugs All Looks Good I Think This Could Be A Kill Switch Issue Or Electrical Not A Mecanical Issue Does Any One Have Any Suggestions.

    Sound to me like a fuel restriction somewhere. Have the fuel lines been replaced??? Clean out the filters in the carbs. Fuel selector switches tend to bad on these things as well.

    Welcome to the Hulk. If you feel it's not fuel related, look into ohm testing the stator and coils inside the elec box. Look for a loose or poor connection at the ground cable. Double check sparkplug gap and what plugs do you have installed in it? Usually a high speed miss is fuel related though.
