Hello fellow boaters,
I have a 2005 Sundancer 280 with twin 4.7 Mercury Engines. I just encountered a very unusual problem and needed some help. My boat used to take off and plane within 30 seconds at around 3500 rpm, however, as of about a month ago this has stopped. When I floor the boat, it barely moves. If I'm idled, it runs fine. The lake was as smooth as glass yesterday and was pushing it full throttle and still looked like it was on 1000 RPMs, even though the reading was at 4000 RPM. The boat won't take off at all or plane, and was wondering if this something I could fix myself. Any thoughts on what could be the issue and how to fix it?
Note: The boat only had me and one other person on there, so it should've taken off. Also trim tabs were down.
