Hi All, Just encountered my first problem with my 18 month old boat. It has a 2003 525 efi with an XR Drive, 28" 4 blade prop. Boat has ran great until yesterday. Was out on the lake and running great at about 5200 rpm and 78-79 mph. Stopped and took a swim then got in and ran back up the lake and only could manage about 4800 rpm and about 68-69 mph. Took the boat back today and ran it again with the same results, despite putting a new prop on and adding gasoline treatments with the hope of it being water in the fuel. I am at a loss, props are fine, didnt hit anything, no vibrations, hull is OK, bilge works fine. The boat comes out of the water fine it is just at top end it wont get up and kick it up the last 300rpms. Boat has 60 hours on it and I change the fluids constantly. I am not sure if it could be a fuel filter/obstruction in the lines?, an impeller issue? bad gas?, Out drive malfunction ( I just had AMSoil put in the outdrive) Any help would be very greatly appreciated. Thanks Jim
