Im new to this forum and seeking some help, perhaps someone will be able to answer my question. I am an owner of a 2004 Sugarsand tango jet boat with 175 HP mercury sport jet. I am not the original owner and after taking the boat out for the first time this weekend here is the problem im having. I was out for about half hour on the lake getting on it here and there, then went tubing for a little while before we parked on the sand bar. We were on there for about 2 hours or so with the music going, then we went to take the boat out. Not even 5 min into the ride off went a loud constant beep. So we turned the boat off and on again but within a few min again off it went. No idea what it means but I took the boat in thinking that maybe it was a bad battery or something. So I went ahead and put in a new battery, checked over a few things and went to try it out again same thing happened but this is what I noticed. If I put around the lake under or right around 2000 RPM nothing happens I can be out there with no beeps. As soon as I get on the throttle in a few min the beep comes back. Sometimes in a min or so sometimes maybe in 10 but it?s a constant loud beep like the beep that you get with the turn of a key just constant. With just a flick of the key the beep is gone for a little time. I thought it might be an overheating issue but with the engine turned off right after the beep its cool to the touch. Then ive read that maybe it?s a oil system warning buzzer but the oil tank was full to the top and during the course of the day a good bit of the reservoir was used. Other than the beep the boat runs great good power throughout. Is there any better way to diagnose this problem? Any ideas? Please help, thank you all for your time.
