    hydrofoil

    Have read that installing a hydrofoil is supposed to help with chinewalking. Does anyone have one on or has anyone heard if this is true or not?
    Thanks-

    I talked to a man one day that had a boat same make/model as mine that had installed one hoping it would fix it. He said it didnt help at all. If you ever look back there while someones driving the fin would be out of water.

    Dont waste your money. The cavitation plate where the foil mounts to is out of the water when on plane.

    I have a 2001 TR-19 with a hydrofoil on it and it does not help with the chine walk..... it does help alot with the holeshot.... loaded with 2 guys, gear, full live wells, etc it will jump out of the water.

    There are no tricks to stop chine walk that won't hinder performance. You have two options, drive slower or learn to control it. My Tr20 is the first boat I've owned that would do it, I got here on here, read the basics of what it is, how to correct it, and good setup advice and had it down after a few passes down the lake. It seems intimidating but once you figure out how easy to is to keep it balanced on the pad you won't think about it anymore.

    Now granted if you're running 90 I'm sure it's a bit more involved but for a 70-75 mph boat, it's not bad.

    Dont waste your money. I had a serious issue with chine walking with my 2000 TR W/250XS. I resolved the problem but not untill I tried everything possible. My problem was at 70mph I could not controll it at all.. My problem turned out to be my hydraulic steering needed to be rebuilt. I can now run it at 80mph with very little chine and one quick jerk to the left takes care of that. Check your steering. On dry ground take your motor toter off, Trim motor half way up, Now try to rock the motor back and forth. It should not move either way more than a 1/4 inch either way, If it moves more than a 1/4 inch than you need to rebuild it. Cost about $200.00. Since I found this out I have helped many of my friends with the same issue. Even some brand new hydraulic racks have had too much play and had to be replaced. The play allows the motor to get into a rhythm and you cannot stop it.
