I have a 1998 290 sundancer with twin 5.0 efi with under 400. Hrs on both. I have taken it for its first trip out this year and it ran great but WOT could only get 4200 rpm and port motor seems to be lagging. When i go WOT the left motor goes to 3200 rpm and the right motor goes to 2800 rpm. It takes about 10 seconds for them both to start to climb and then the boat will plane off. Today i took it out and the same thing with the rpms but would not go over 3400 to plane off. What can i check. Props were just redone and bottom is clean paint. Seems like a loss of top end power that is needed to drop nose to plane
