Alright, alright, that's enough of that. The way some people drive they need seat belts. I wasn't implying they should be required, I just wondered in that particular instance if seat belts would have kept both anglers from being ejected. Spearing a wave didn't kill them, getting ejected did.

Most likely chine walk and trimming down or slowing down will solve the issue.

When all else fails, read the US Navy's in flight missile mechanics hand book for further options

I see all of the time people trying new props or messing with motor height trying to get the most top end speed they can. The only time you will accomplish speed gains from motor height adjustment or a different prop is when you learn how to control the chine. All boats chine at a certain speed, some more than others. If you are slowing down or trimming down when your boat starts to chine then you will never go faster than that at which it started no matter what modifications you do. A friend of mine with a bass cat 200 merc complained his boat would only run around 63 / 65. He wanted me to drive the boat and see if I could figure out why it was slower than what others claimed they could run with the same set-up. I got it up to 72 .... he said was slowing down when it started to get out of control.

I have given boat driving lessons to probably 25 guys over the years.

Where do i sign up

Its not chine walking. Had the boat well over a year and know how to drive it. The rear end is sliding out to one side, not just rocking like chine walk does. I will check the hydraulic steering and see if it has any air. I checked all bolts last night and all are tight. Thanks for the input guys!

This discussion about steering issues may have very well saved your life. Please check everything on the steering system in your boat.

Send me five easy payments of 69.95 per month! Lol

Check and make sure your skeg isn't broken off.

Lol. Guess i will figure it out myself. Lol

Those guys there rock. Keith is great to work with and has always treated me great

Actually, this sounds more like gearcase crabbing, also known as prop walk.

Prop loses bite for just a second.

Probably need to lower your motor just a little.

My boat tries to "walk" a little, but not until it gets right around 75mph or so and then it seems to settle back down at around the 80-81mph mark after I bump the trim down a hair and bump the jack plate up a hair.

Each boat is different and they all have their own little nuances...

I have to agree that what you are describing is not chine walking at all. You describe the back end slipping out from under you. Kind of like a high speed drift but with rear wheel drive? Loosing traction at high speed? If I try turning to sharp at WOT with motor high I feel my back end beginning to slide out. Things can get crazy real fast if we try to push past this limit without adjusting something. My choices in this scenario are to A. Slow down a little. B. Trim down a little or C. Back of the sharpness of the turn. You know your own boat so if this is a brand new sensation/problem or you feel it at lower speeds obviously you have one of the aforementioned problems that others have posted. High speed only? Could be simply your boat telling you you have found �the edge� and are at the limits of your present set up. Good luck.
