Just bought 2003 33 outlaw 290 hrs with 496 ho's and having trouble getting over 4300 rpm.. 4 people, cooler, 1/4 tank fuel, running around 50 mph at 3200 rpm.. tabs down around 6-7 and drives around 2-3.. 26 bravo 1's.. any ideas where to start? Been told these run 5000 rpm no prob.. at about 4300 I'm running 63 ish. . Tps, cap rotor, plugs?? Throttle cables??

Drop some weight, raise the tabs to 1 and drive out to 5, your dragging a ton of tab at 6-7 if they are conventional indicators

Im with red. Less tab and more trim.

Are you shure you don't have your figures switched ?....tabs at 2-3 and drives at 6-7 sounds right.

If that's the case,
1. spark plugs
2. fuel filter ( some have an internal filter fuel pump assy, some have an in line)

Your short about 10mph

On my gauges, tabs indicators at top are up and at 9.. on my drives, in is at the top and at 0

Are you sure you have 26 b1? 3200 @ 50 is 3% slip using 25.5 p as b1s run small.

Or rpms correct? Though 63@ 4300 is about right at 9% slip.

Easy fix, no power on 3 and 5 on starboard side. No spark. plugs all around!
