TITLEWAVE 0 Report post Posted March 13, 2010 i have a 2006 290 scr with twin volvo 5.0's, i am a first time boat owner and last summer i was cranking up the boat and someone crossed my path, i got scared and pulled hard on both throttles, at that point i went from forward to reverse at 3500 rpm, i broke the splined sleeves on the outdrives, before that the boat was running good. after i had the outdrives repaired the boat never seemed the same, my port engine doesn't have the power the starboard does, and it acts up and seems to go into partial shutdown sometimes, two dealers can't find anything wrong and can't find any codes in the computers. any thoughts ??????? julius Share this post Link to post Share on other sites
