[QUOTE="DaleH, post: 400865, member: 15636"] Oh, one last thing ... the impeller is the WEAK point on that motor (small sized for the rated output, which is closer to 45hp says the gurus on the Scream&Fly forums) so make sure to replace it at least every other season ... even if you don't think it needs it! They are smooth, quiet and have a great torque range for a 40hp OB, with those 4-cylinders running her. [/QUOTE]
