Is it normal in the 2000 year model Challenger 1800 with the 210 Merc Marine Jet Drive M2 to have such effective turning performance when cornering to the Left but be so much less inclined to aggressively corner to the Right?

I also feel like a guy my size 220lbs tends to really through this little 17.5 ft boat listing to far over on when in the driver’s seat. However, when I'm in the passenger seat with my buck 15 girlfriend driving the boat sits perfectly evenly.

Went ahead and replaced the oversized after market Marine Battery that sits behind the Driver with a 30lbs lighter Optima hoping that would help. And all heavy storage is kept on the left side of the boat, but still no impact.

Both of your concerns are normal. You have the helm, cables, and controls on the drivers side. I also know that jet boats always turn better one way than they do another. It's due to the water entering the pump and getting spun in a certain direction.

G,day,
Yes i would say it is normal for a boat to corner like that, but it is usually to the right better, i think it has something to do with the rotation of the impeller and the thrust that is produced. The vanes in the pump housing are supposed to even it out , but they can only do so much. Check that the pump is aligned properly to the hull of the boat and that the nozzle points directly back when steering is straight. Also make sur you get the same amount of travel to both sides.
On the second note listing, yes they are prone to weight change but should list to the side of most weight, from the factory they are pretty well balanced. My mother was in the back seat yesterday and i asked her to sit in the middle because it made a difference and she is only 50kg. I think your turning prob's and listing prob's could stem from the same thing, jet pump out of alignment. It could also be bad alignment of trim tabs if you have these, i have read these can effect list heaps if not straight. The other thing i thought it could be is water, these hulls are made of two layers of fibreglass with wood in between, if you have been unlucky enough to get a hole in the glass, water may have soaked into the wood making it heavier on one side, hope this isn't the case.

Mine does the same thing. It won't turn to the right at speeds over 18 mph. I thought it was related to the staor or jut pump, but its NOT AT ALL. I replaced all of that thinking it was, but it didn't change anything. This was a damaged stator assembly and bent ride plate that the staor bolts to underneath....what a bummer. I would love to hear if anyone has any solutions to this crappy problem.
