    Bullet guys need your help!

    So I just put a 2008 250 Pro XS on my 21xdc. Motor has 390 hours. Starts and idles great! First time I used it I had no problems. Second time I took it out I ran about 5 minutes and shut down and fished for 30 minutes. Jumped to another spot about 2 minutes away and everything was fine. Went to leave that spot after 30 minutes of fishing and it wouldn’t come out of the hole. Started cutting out really bad almost like it was in limp mode but was throwing no alarms. After a few more trips there’s no consistency. Sometimes it does it coming out of the hole. Other times it comes out fine and starts in at 30mph sometimes 40 and sometimes 50mph and other times not at all! Sorry for the long post. Guys on the mercury board had no input but figured you guys might have an idea.

    If there’s no alarms...I would look at the fuel system first. Tracker valves around here have been a big deal. Also something simple....make sure when you shut your back lid it’s not crushing the bulb....

    What is your water pressure? I had a similar problem and it ended up being the gasket between my power head and mid section. Just a thought

    +1 on the fuel system. Check the pulse pump, will not hurt to rebuild it. May have crud from old merc fuel lines in it.

    Tracker valver and diaphrams are either good or bad. I would check coils first.

    Got the boat running and on the water. Me and my son went for a test run and it was ruining 78-79 and my water pressure gauge was over 30 psi. Time to start adjusting the motor
