i have an 01 21 foot ultra with a fuel injected 496ho, berk pump, all the other standard stuff. i bought the boat about a year ago and i've been on the search to figure the boats #1 problem since i got it. here are the symptoms.
1. after letting the boat warm up for a short time or a long time (20 minutes) being long, or after idling for an extended period through a no wake zone up to 30 min. the main issue is this. when i first go to get it up on plane it basically revs up a bit, cuts out for a second, revs back up, cuts out. it does this a few times until i just wait for it to get on plane then it's ok once on plane i can jump on it and it doesnt seem to have an issue.
2. if i get through the first time of it having these symptoms, say to run up to an area, then throw a skier behind the boat, the symptoms aren't there.
I've had the boats computer remapped twice. symptoms are still there. i'm having some electrical issues with the boat as well around the ignition (key). those are going to be addressed this week by my mechanic. could electrical problems be a cause or is it more than likely a thermostat/ temperature issue.
thanks in advance for any help. this has been a pain in the ass the whole time and i'd like to avoid throwing heaps of money looking around at various solutions when maybe one of you guys out there has had this same experience. thanks again
