Recently i adjsuted rave valves and cleaned , i had both engines running the next day i tried starting the boat . IT WONT START . I FOUND I HAD A FUSE OUT I FIXED IT IT STILL WONT START . THE ENGINES TURN FINE . BATTERY IS FULL CHARGE . I CHECKED ALL FUSES . NOT SURE IF I AM MISSING ANY, DOES ANYONE KNOW WHAT I CAN DO FROM HERE . THANKS NOT SURE IF THE FUSES I REPLACED COULD BE THE PROBLEM .

does anyon know where i can get my engines rebuilt challenger 1800 1998 ,i live in hawaii and would need to ship engines by crate . please advise

anyone out there know why one of my engines on my challenger 1800 1998 will not grap full rpm , it starts going then the rpms drop back and forth 4500 to 7000 .

when i full throthle it wont go . the other engine runs just fine . help summer is half way through

my boat sat for a couple months due to rain , i got it up and running , i have a problem with one engine . when i am on the water and open her up one engine goes rpm 6+, the other engine stays at about 3+ rpm then as i keep trying to get it going , she will catch and rev up to 6+ rpm but for couple minutes then it loses power again back and forth 3+ rpm to 6+ rpm like something is stuck in fuel line .
i changed plugs, i changed fuel filters same problem . when i take out of water engine runs fine at high rpm . it only happens in the water . does anyboday have any suggestions . thanks . ]
