Wow sounds like more than a battery issue if hull leans to one side. Sounds like possibly water under floor or defect in last few inches of bottom of hull. Get a four ft level and place on bottom of hull lenghtways on both sides and see if both sides are same. Many manufacturers put a hook in last three inches of bottom to give lift and keep bow down, allow faster planing and to prevent porpoising. Make sure if you have them they are the same profile. Also stand 10 yards behind boat and look at motor on trailer trimmed down and make sure motor appears straight up and down. Let us know if any of these are out of sync. Your trim should be able to lift weight of batteries once rolling along good if motor has enough power for boat. Also different props with different cups provide different lift but these have nothing to do with listing to one side.

what size motor?

Kinda agree with Bigjim. Does the boat lean when stationary and or just on take off? If it only leans on takeoff then I would follow Bigjim's suggestions. Good luck and please keep us updated.

i would call a rep at the bluewave company itself, before i go thru any expense or trouble! remember, some dealers just want to sell, then they forget you!!!

If it leans only when running then check your steering torgue tab under the cavitation plate,trying turning all the way to the left or right and see if that makes a difference.You could also change your prop to more of a bow lifting type prop.
give us more info on your boat,what motor,hp,what brand and type of prop(3 or 4 blade).Your motor hieght could also be a problem if it to low,dealers like to mount motors to low.
can you put the batteries under the console?

Just trim it up as you get on plane!!

i mean when u buy a whole rig from a dealer set up, dont u think when u take it out on the water, you shouldnt have absolutly any problems with it??? its like buying a car! if u buy it and it runs like crap, u take it back and they take care of the problem!!! why should boats be any different??? when the dealer sells it to you as is he is saying this is a great rig ready to run!!! i blame the dealer!!!

Beast i would imagine he added his trolling motor himself after the sale, but they should still try to help. ive owned a couple 18 ft bay boats and ive always had batterys in the counsil works best on smaller boats. as for as leaning everyone gave good info, make sure ur weight is balanced then as stated above try moving your annode skeg first, that should do it, but a high lift prop could help. on larger boats with larger v's they use hydraulic tabs and trim down a little on the problom side leveling it out, but you should not need that.

salesman said no problem with troll motor and batteries in front!! so whos fault??? salesman said no problem and rep says no??? who do you believe??? salesman just wants to sell!!! this guy could sell used cars!!!! when u buy it, you are talking to a salesman, not a rep!!!!

You need to try moving the batteries to console if gas tanl allows if thats where tank is mounted as usually is on less expensive boats. If you break suction of hull to water you instantly free up apporximately 4 to 6 mph depending on overall speed and hull design. This will allow you to get air under hull and reduce suction friction.

I had a 18' Blazer Bay with a 115 Yamaha four stroke.I had a 24v troll motor with two 29 series deep cycle batteries in the center console. The cranking battery was in the rear right compartment. This boat topped out at 41 mph with a full fuel tank. You need to balance out you load. Salesman just want to sell most of them have no idea what it takes to make a boat run right. Too much weight foward will kill your speed, too much rear weight will make it squat.

It sure sounds like you have a weight distribution issue. Before going to the expense of relocating the batteries why don't you disconnect them and move them to the console area (or where you plan to relocate them) and then try the boat on the water. Sure, the trolling motor won't work then but you're only testing the weight distribution out now. Relocating batteries can be expensive due to the heavy cable needed and sometimes the labor.
