1. If you're just one person alone in a tin 16ftr without heavy flooring with a 40 on it, prepare for a rocket ride. Fast and fun and way safer in waves than a squareface.
2. Specs re draft depth are avail online for a lot of hulls if you look hard enough. But really, unless you want to do swamp, the hull will only draft maybe 6 in. and what you really need to look at is is not the hull, its whether there is a functioning trim bracket (notches, an adjustable pin but also a "lift it out and it clicks and stays out" mechanism in the motor bracket so you can run with the prop shallow, then also pull the lower end clear out of the water.
3. If yes to #2, get a pair of long aluminum oars (backup if old engine fails,if there are oarlocks) or at least one long light paddle. That way if its not rocky you can glide toward shore, turn the boat lengthwise parallel to shore at the last moment while quick pulling up the motor lower end out of the water, which "lands" the whole length of the boat, then use the pole on the lakeside of the boat to pushpole the boat's shoreSIDE right up against shore. Then you can step out of the middle of tbe boat, avoiding the height and tippy "leap" of exiting over the bow. This only works if you can click your motor's lower unit up out of the water.
4. Old motor. Gotten it checked over ?
5. Too much weight in the stern is the biggest issue un tbese boats. if you're alone. It'll drive the stern inches deeper into the water and your bow might kite. Consider rigging so your battery, gas tank, and trolling motor are all in the bow. You'll find she gets up on plane and just flies across the surface once you get the right trim angle locked in.
6. If you really need a swamp rocket consider a mechanical jack plate, adjustable or fixed is cheaper, to set the prop as shallow as you like. See Cabelas, BassPro.
7. If you run shallow and rocky a lot, e.g., rivers, there are metal prop guards of various shapes to protect the prop and/or skeg.
Bottom line, if the hull is sound and not leaking, focus on whether this motor is good. If yes, I think you'll like the hull and the upgrade difference will feel like motorbike to sports car.
Good Luck!
