i have a 31' vindicator with twin 280 hp merc outboards at around 80 mph the boats starts to chine walk . i have even change the drives around and it still does it . would a set of trim plates help this and how long do they need to be.

trim tabs will work. should not need any more then 12 inches wich is the smallest you can get with k kieffifere. don't go any longer boat is to small.

Chine walking is a result of flat water

You may want to ask Darin @ Houston Propellor but I've heard that chinewalking can sometimes be related to too much prop diameter. I'm not an expert but have heard that can be one of the reasons....how's the bottom of your boat?

Well...this should get you started! Good luck and let us know what you find is the culprit.

Treadwellmotorsports

that can be a reason. it certainly isn't flat water.

check your motor mounts. If the are old it will cause chine walking. You need soild aluminum. You can buy them at bobs machine.

Do you have a little toe in on the drives? About 1/2 inch difference between the nose cone and the end of the prop shaft might help.

Are you spinning in or out?

the motors are 2.5 offshores they have soild motor mounts
