    Well THERE’S your problem! You need a long shaft extension kit for your 18. You’re ventilating the prop once the water breaks from the transom. Ventilation is NOT the same as cavitation. I’m pretty sure I have the extension housing and possibly some of the other bits, too.

    thanks. what does extending it entail?
