'03 Nordic heat level problems
Hey guys, I have a 2003 Nordic heat and when Im on plane the boat leans to the left alot. It sits level when im idling. Even if my right gas tank is full and the left is empty, it will still lean to the left. I have to put down my left trim tab at the number 2mark on my tab indicator to plane level but this lowers my speed. Has anyone had this problem before? How do i fix this without using my trim tabs?
My set up:
2003 Nordic heat, 509 carb, 3300 Whipple SC, Imco SC extreme out drive with standard Imco lower, Brovo 1 4 blade 30p prop.
Thanks

Hi Jody,
This is an issue with a lot of single engine boats with some horsepower and right hand rotatation (95% are RH). That's why the factories normally put the driver's station on the right side of the boat. It's your propeller torque rolling the boat over to port.
I normally run about 1/4 tank more fuel on the driver's side, and mine is OK. You can tab it out, but that will scrub speed off, and can cause some erratic handling at different speeds and in turns. You can also move your passengers around, with the heavier ones to the right or starboard side.
My boat has a water tank on the port (left) side, about midship, a really bad spot. If you have one too, run it empty. Water weighs 9 pounds per gallon, and it really rolls the boat over to port. I know it simplified the plumbing where they are, but these should have been mounted on the transom on the right side.
If none of this works, check your hull for hook or rocker with a straightedge, like a 4' level.
Sounds like you have a really nice boat. Good luck and keep us posted with your results.
Regards,
Steve

Hi Jody,
You do seem to have an extreme version of this roll to port, that we all have, but to a lesser degree. One more thing worth checking........there could be water trapped under your floor on the left side of the stringer. Again, unlikely, but not impossible. At the transom end end of the main stringers, there are 1" holes that are used to drain water behind them into the bilge area. You might want to make sure they aren't clogged.
Regarding propellers, the 4 blades are not as bad as the 5s, so that's probably not the problem.

Steve

Hi Jody,
Yeah there is defintely something wrong with your setup. That just doesn't add up.
I see where you are in Baton Rouge, LA.
BobL is the Texas Nordic dealer. He is an excellent technician on motors and setups.
I wish you could get you boat over to his dealership in Spicewood.
I know he could diagnose this for you in person, and get you set up properly.
Best Regards,
Steve
