"i have just purchased this boat and love it but dang it seems slow .. what are the max recommended rpms , what should the speed be ?? boat rides great and handles well just dont know what to expect . this is my first boat with a "direct drive" . Just dont want to over-rev it and damage motor or trans .. also leaks at shaft seal pretty good , can i tighten packing . ?? thanks .. any other good info would be greatly appreciated ."

HP probably in the 150 to 190 HP range... Max RPMs probably in the low to mid 4000's. Max cruise should be no more than 75 to 80% of the maximum that you observe.

150 to 190 HP is not going to move a 25 ft boat along all that rapidly... More info on the model of the boat would help. Also more info on exactly which engine.
