Not very experienced with boating, have a question about engine size/weight. I have a Gregor 12 foot aluminum boat with a Honda 15 hp 4 stroke. Took it to the water once but did not get it away from the dock for various reasons too embarrassing to mention. But, when I stepped into the boat it looked to be far to low in the back. The boat is rated for up to either 20 or 25 hp, so hp wise I am good. I weigh approx 270 lbs. Still plan on trying to give it a go this season, but anybody out there have experience with this combination on this size boat? Not sure how much room there should be between top of transom and water to be safe. I have a 9.9 two stroke which ways much less, but spent quite a bit on the Honda so really want it to work...lol.
