in this case, a good thing. the chase model tends to sit low in the back, many with the deck drain through hulls at or slightly below water level. i suspect the vast majority of the reason yours sits high is due to the single engine.
Believe it or not this photo was actually taken after a fill up of 200 gallons too. I noticed the chase 273 sits low. This is a 2011 fisherman 273, still unsure of the difference as this is the only 273 fisherman I’ve ever seen.
seems to be a chase with a fisherman name put on it. probably when they were re-doing their naming convention. if you go to GW website and look up the manual for a 2011 273 fisherman, it brings up the manual for the chase.
