Any small boat will chine walk as you get close to the max hull speed and you pull the drive up out of the water.....basically you don't have much hull in the water...just the drive is in the water...tabs won't help at all.
A shorter lower unit will give you more speed but also more chine walk. Trim the drive down a little bit and slow down....you are at max safe speed for that hull......
Not true... tabs will help if they are properly isntalled and are the correct size for the boat.
