I have a 24 ft. Pontoon with a Johnson 140 on it. There seems to be a lot of ventilation when I throttle up fast when it gets to about 3000 rpm. I can let off and bring it back up slow and can then get to 4000 rpms when it starts again.<br /><br />I bought this pontoon used and believe it is not set up right. I was able to lower the motor on bolt hole to it's lowest position.<br /><br />Now for the prop - it has a 13 X 19 on it now.<br /><br />What are your thoughts, what should it be?
