What's causing the boat to list?
Hey all, I put up a post a while back about my 20 MA listing to port while underway. After I ironed out the bugs with the Bennett trim tabs, it seemed to help. But the problem is back and seems to be worse. At around 45 mph, the boat dives to port and almost seems to want to roll over. Very Scary, and thats with a single tab down to compensate. And the problem seems to get worse as the gas tank begins to empty. Could the tank have shifted? Any ideas, cause I'm out of them?

Re: What's causing the boat to list?
Sounds differant.. What size motor and what is the rotation? It sounds like the fuel tank is helping to keep this from happening and as you burn fuel the boat gets lighter and it wants to roll. Have you adjusted the anti hook fin on the lower unit?, is the motor straight on the stern(up and down). Check the hull too. you may have a cup in it .. find a long straight egde and place it in the hull and look for cups. Motor too high?.. more input!!!1

Holy Mackeral ! Looks like pipes has bout' got everything covered,I'd also say cupped.Fuel tank can't really shift,But a baffle can break allowing the fuel to go on one side.?. Kinda remember My ol' girl(20 MA) listing a lil to port,trim tabs took care of it if "HOOVER" wasn't aboard.Dog biscuit to the starboard bow & Instant ballast !

Hey Pipe - where is the anti hook fin? I get a slight list to port when running around cruising speed - I assume it is from the rotation of the prop.

Re: What's causing the boat to list?
Pipe Dreams, thanks...I've got a 1998 Merc 175 Offshore, with a four blade stanless prop. My mechanic buddy said to adjust the fin if the wheel/boat pulls to one direction. This thing literally dives to port. If the hull has a "cup" in it, what could cause it and how do I fix it?
Capt Brad, I had two healty size people sitting on the starboard side and it didn't quite cure the problem. At slower speed its more managable, but when I have 30 miles to run, I gotta move. Mark ...scary ain't the word [ June 03, 2003, 05:41 PM: Message edited by: 84 SeaCraft ]
