    has anyone removed these? they seem like a big drag in the performance, you can definitely see it in the wake.

    I've seen examples of when people have removed them hitting rocks but never on purpose. Generally you don't want water forced into your engines. Or at least I don't. They are set up that way for a reason.

    Welcome to CSR! We like to see pictures of members boats so sign up as a sponsor and post away.

    I believe they are set up so it get quite when your on plane... So you don't hear loud exhaust as your cruising.... I would not recommend removing them... And little things like that is not gonna slow you down..

    A 32 footer with twin 300 hp motors would need a LOT more horsepower to worry about uderwater fitting slowing you down

    We added them to our boat. There was a bit of "station wagon" effect on early 32 Opens and Tiara was looking for a test hull to retrofit. We volunteered to have them added during the off season, and found the upgrade to be very effective at solving the problem. Glad we added them. You might regret taking them off.
