Like Coach said www.tigeowners.com
will have a ton of information about Tigé boats.
In my RZ2 I run about 1850 pounds of ballast.I have the stock ballast with additional sacks.
I run 650 in each side of the engine and about 550 up front. The front doesn’t need a huge amount of weight. I also have Taps at 5-6, speed is 22-23mph and 70-75 ft line depending on rider. I am still playing around with weight and speed but so far this has been the best.
