Have a 2002 Charger 195 with a 2002 Mercury 200 EFI. The boat had a quicksilver 25p 4 blade on it when I bought it with about a 4" ptp. Was pushing 6K to run 50mph. I called Charger directly and they said to switch to a Tempest 25p and raise ptp to 3.5". I got the plate moved, put on NIB tempest plus 25 and took it out. I can only squeeze 61mph at 5600 rpm. That is myself and low fuel. Just wondering if switching to a 24p would be an option. Have not had a chance to take it back with the plate moved up to 2.5" which is what I'm getting from quite a few people. Is it possible that moving the ptp up 1" or 1.5" could solve this issue or is it strictly a pitch problem. I'm thinking about sending the prop off to Marks props to have it worked but I guess I need to bump the plate up some and use those numbers when sending it in or will that matter? I'm new to this prop stuff and am trying to make it as simple and cost effective as possible. Thanks
