    When is the last time you changed your fuel filters? How old is your fuel?

    I had a similar issue last year and posted the issue on this forum.  I received Lots of interesting inputs that you may find useful...you may be able to review on "my discussions" page.  I eventually discovered that I had a trim tab issue. I had a leak in the hydraulic line feeding my trim tabs, thus preventing them from going up/down and thereby preventing me from getting on plane.  I was really surprised that the non working trim tabs had that much impact on my boat, but once repaired I was able to get on plane without issue.

    There could be a fault code on the engines causing them to go into guardian mode, or whatever Volvo calls it.
