Re: Ballasts on a 17 ft bayliner?
There are a few important thigns here. How much weight, location of weight, and planning speed.
Your boats planning speed will change some based on the weight you have in the boat. You need to make sure you have no issues stayign on plane at the speed you want to ride. If you do, the drive will not be able to give it enough throttle qquick enough to keep it at a constant speed when it start to fall off plane and bog.
So, as mentioned above, experiements with some friends in the boat. Have them sit in different location and see what it does. Put a fair amount of the weight in the bow. This will help get the bot on speed and maintain speed as it will cause the boat to use more of the hull.
The amount of weight won't be much. You are very underpowered and on a very small boat. Too much weight makes for a dangerous situation. Again, experimenting with how the boat re-act with people in it is a good place to start.
I wouldn't worry too much about all this in a 17' Bayliner. It will never toss out a good wake to move on to advance tricks. If it was me, I would get two 250lb bricks and put them in the rear corners of you interior, and a 500lb sac in the middle of the bow. THat should be close or even a bit above you USCG Weight, and will even out the weight of the boat. IF that doesnt work, then move the sacs you have in the corner to right down the senter of the boat.
Don't ever surf behind an I/O.
