Hey guys been working on the setup of my puma adv now for awhile. I’m running a 2015 Mercury pro xs 250. Purchased the boat used and a cylinder went down shortly after. Purchased a new power head short block from Hinkle marine and had local dealer install it. After break in been trying to get boat set up. Initial setup before motor went down was with a 26 fury. Boat ran 76-77 @ 5800rpm two guys tournament load. Plenty good Now it runs more like a 200 or 225 Same prop (26 fury) setup 67-69 @ 5300 rpm with two guys Tried a 26 bravo xs 68 mph @5500 Tempest plus 26 71mph @ 5600. Just not what I expected with a 250 Ran compression checks, verified full throttle with hot foot, changed plugs, coils, fuel lines Nothing seems to make much difference Thanks for the help

First, testing for top end speed should be done alone to keep weight consistent. If you were getting 76-77mph with two and tournament loads, those number should be obtainable by yourself.

Biggest difference, a loss of 500 RPMs with the Fury.

For more input, post this issue on BBC, Mercury forum, have your engine serial number stated in your post.

Getting 73-74 one person. Loses down to 68-69 with two guys. Smaller pitch props gets me more rpm but no more speed.
