Re: 2272 seaark ventalation ?
Jon boat handling is not on the same level as V-hull handling and you do not mention if you are using a steering wheel from the side or center console.
If you have tilt and trim....... you might have to trim down before a hard turn. You might have to lower the motor a notch which will take a bit off top end but, might help.
As far as the dent..... VERY tough to get the dents out of aluminum. The metal does not like heat and could change the properties..... some people have filled the dents with marine tex or PC-11 just for piece of mind.
