I have a OMC 17 1/2' Roughneck Tunnel Jet Boat on a Shorelander Bunk trailer. The entire setup fully loaded weighs about 2600lbs. I have had the welded seams on my aluminum fuel tanks split twice, I can't keep tail lights on, and I've lost a wheel bearing in the last year. My fishing spot is 12 miles of gravel road that is not the best. I have learned that the previous owner replaced the original axel with a Dexter 3500lb unit. He also changed the springs to two 1750lb leaf springs. I am wondering if that package is way to stiff for the weight of my set up? I am mindful of how rough the road is so I don't travel very fast. The fuel tank is a factory welded fuel cell. Its located at the transom. I reconfigured the mounting hardware of the tank so it has some cushion and is not rigidly mounted. Would a plastic tank be any better? Highway driving seems fine. My 15" tires say to run at 50 PSI. I've read where I could lower the pressure to improve the ride but don't want to blow a sidewall. I'm looking for recommendations on what to change or do?
