Not enough power on my 40 HP Evinrude


May 25, 2013
I have an Aqua Patio Pontoon boat with a 40 HP Evinrude. The motor runs great and fires right up. However I feel it is not running at full power. The motor seems like it needs to be adjusted. I do not have enough power in reverse to pull it off of the trailer. In addition, it does not seem to have the speed that other pontoons have with the same type of motor. I believe I need to make some type of adjustment to the throttle cable or the linkage, but do not know what to look for. Again, the motor runs great, it just seems to lack full power. Money is tight and I would prefer to attempt this on my own, versus taking the boat to a dealer. Any advice on where and how to begin troubleshooting would be greatly appreciated.
