I bought a 2005 290 SLX this summer with twin Merc 350's. I love the size and capacity of this boat and where we boat on Lake of the Ozarks, it allows us to run much farther down the lake where the waves can be 3 to 4 ft on a weekend. But what I've struggled with is being able to find a nice cruising speed and maintain it. For example - I get the boat up on plane, at throttle back to hold my speed at say, 25mph. But slowly it will lose that speed and drop off plane. So I throttle back up and try to do the same thing at 30mph. Once I back the throttle down a click or two, the boat either a) begins to slow again or b) continues to accelerate now that it is on plane. I have tried the trim tabs but that doesn't seem to work well. And trimming the engines up - I quickly get washout. Any 290 owners on here that can advise me?
