[QUOTE="RadarJet, post: 354812, member: 8862"] Really appreciate the help here. I just took ownership of the boat, but it has been in the family for the last 8 years. As far as I know, the tach has always been like that. What got me thinking about it is when I bump the throttle the tach jumps to 3,000 rpm but the boat hardly moves. I've got to push it to 4,000 rpm to break 5mph, and it feels like a barge then. We were traveling about 25 to 26 mph last weekend with the tach reading 6,000, so I doubt a key is broken. The bottom front of the jet foot is about 1/4" higher than the bottom of the hull when trimmed all the way up. There are two holes remaining, so I'll move it up and see how it goes then. Ill clean the electrical connections tonight and check the rest of the electrical while I'm at it. My last question would be is it harmful to push the throttle all the way up to touch the rev limiter to just see where it is at, or should I stay clear of there? Thanks again! [/QUOTE]
