hi guys great furum, I have a 2000 2100 with a merc 225 efi. at about 73 the boats starts chine walking it gets real bad at 76 I was told that I could eliminate some of this changing to a three blade prop. currently running a 4 blade 27 p power tech prop. I would like to get some input from others with similar boats before dropping a lot of money on here say also heard blueprinting my current prop may help and would be cheaper
