I bought a 190 with a 200 optimax recently. Its got a 25 pitch tempest and 10 inch jake plate. I can hit right at 70 gps by myself and 67 with two people and that is with me hitting the rev limit and the boat not really out of the water all the way. Is this about what I can expect out of the boat or can I get some more. Been thinking about changing prop. Any help would be appreciated.
