I have a 2007 stratos pro 285xl with a 2007 150 Evinrude etec HO E150DHLSU ser no 05161005. Have trouble getting on plane when fully loaded and livewells full with 2 in boat. Mechanic said that computer readout showed I was overpropped. Only achieving max RPM of 5350 when 5750 is supposed to be high end of range. Mechanic suggested I go from Raker II pitch of 24(currently) to a 22 pitch. Does this make sense to you guys? Dealer went out of business since I bought it. Is this something I should talk to Stratos about covering the swapout or Evinrude?
