There is something wrong with the way that boat is rigged. It is sitting way to low in the back. This is the waterline in mine with 50 gal of gas in it

Just my opinion, but that seacraft, for a 23' is sitting to low. If it was a 20 or less, I have seen them sit a little low in the back, but that is too low for a single engine 23.
