I bought my first boat last September and I have a question about weight distribution. I was warned that it's a heavy boat by the seller, he called it a tank. In a good way. It's very sturdy in big water. So that's cool, but the first time I had a third adult hop in, the boat basically turned into a barge and just plowed water. With two "hefty" adults, gear and a cooler I have no complaints. It gets up on a plane no problem and scoots along just like you'd expect it to. Adding a third, non-hefty adult and gear was too much for it though. It couldn't get up on plane and the front end just plowed water.
It has a 24v trolling motor on the bow. The two marine 12v batteries for the trolling motor are also in the front, not all the way in front, but close. A buddy said he'd try moving the batteries to the rear. So what I'm wondering is, how much weight can you put in the rear of these boats and is this a good idea? Assuming they'd even physically fit. The main battery is already in the rear.
As a comparison, I have a 17' with a 60 HP 2 stroke and my dad has a 16' with a 50 HP 4 stroke, both tillers. My dad's boat slows down a bit with all of us in it, but easily gets up on plane and operates normally. His boat is a little more on the bare bones side and his motor is a good 10 years newer, but otherwise it's basically the same setup, but smaller, and it moves all of us around very well. This makes me wonder if my boat is or should be capable of more.
I also thought of the possibility that my old 1997 2 stroke is just tired (is that a thing?), but it seems to run very well. I also took it to what I think is a good repair shop and they assured me that I have the correct prop.
Here's all the info I can think of and a few pics.
1996 Alumacraft Competitor 170
1997 Mercury 60 HP 2 Stroke (60 HP is the max HP rating)
85" Beam (or close to that, can't remember for sure)
Try moving the batteries? Save up for a new motor? Or that's just the way it's going to be? Any advice from the community would be very much appreciated!
