Just bought the boat priv. party and ran it 5 times before this started happening. Boat shops are backed up 2-3 weeks just to look at it and I think it may be the impeller. I ran a search and saw that these things get clogged pretty easily. Any suggestions as to how to diagnose it. I'm gonna run the rabbit ears on it tomorrow morning and hope it disloges what ever it may be.<br /><br />Thanks<br /><br />Dan

Most engines,outboard and inboard,as well as your I/O,or sterndrive...start with an impeller replacement.Once you know that, you can look at thermostats,risers,manifolds and the rest.As for clogging easy,this is new to me.<br />DHP
