I have a 2006 150hp optimax. At the beginning of the year, from what i remember, it was running over 5000rpm and running around 45-46 mph. Now at full speed i can only get 4600 rpm and just under 40mph on the 19.5ft crestliner sportfish. I did hit a rock a couple weeks ago but the propeller was repaired and they checked internals and said everything looked fine. Any ideas? We did run some quick leen through it. Should this help?
