cavitation plate and transom

[wallydiver1]

i heard on here that the cavitation plate is supposed to be about 1 inch below the bottom of the transom.. i have a 35 merc on a 16 lund.. i was just wondering if anyone could tell me if what they said was right and if it would help give me some speed because of less drag.

Re: cavitation plate and transom

Hi, Wally.<br /><br />The general "rule" is that the anti-ventilation plate (AKA cavitation plate) should be even with or slightly above the keel.<br /><br />Many people raise it higher than that at some risk of prop ventilation, particularly on turns.<br /><br />The higher it is, the less drag and the higher the risk that the prop will ventilate by breaking the water surface.<br /><br />Hope that helps.
