Well I weighed my boat today and it was right at 3,600 lbs, and as some have mentioned before the boat is heavier than the current springs are even rated for 1,500 lbs each. So far the only heavier set of leaf springs that I can find that have the right dimensions are for 1,850 lbs or 2,000 lbs. I'm going with the 2,000 lb for now. I'm thinking about getting a bigger boat at which time I'll get a tandem axle trailer for it as well. I like the tandem axle idea for this boat, but when I trade this boat off I don't know if I could get my money back or not for the new trailer. So I'll just sell it like I bought it but with bigger springs under it. Thanks for all of the help.
