Boat Repair/1997 FOUR WINNS 200 HORIZON
i HAVE A 5,7 VOLVO PENTA 350 V-8, WAS DRIVEING DOWN THE LAKE YESTERDAY FOR THE FIRST TIME THIS SEASON, THEN THE ENGINE SHUT DOWN, AND THEN WOULD NOT START ACTED LIKE IT HAD TO ELECTRICAL POWER AT ALL. EVERYTHING ELSE HAD POWER. HAD A NEW HOT BATTERY. THEN AFTER ABOUT 5 MIN. STARTED UP AND RAN FINE. I JUST INSTALLED A NEW STEREO SYSTEM WITH A AMP. FOR A SUB WOOFER WOULD THAT CAUSE A ENGINE SHUT DOWN IF IT WAS DRAWING TO MUCH POWER??
You need to find out if it electrical or fuel...put the flame resstor on and with the engine turning it should start on carb cleaner the the engine should start and run, check spark on all cylinders...with the system you are talking about should have a new power supply for those....
