When my engine was installed on my 17' whaler three years ago I noticed that the cavitation plate (that is what I call the short fins just above the prop) was above the bottom level of the boat by about 2 inches. I asked at the time if it was alright and was told it was. Since then I have received several differing viewpoints as to whether I should drop the engine so the plate is roughly 1" below the level of the boat - some say yes, others say 'if it ain't broke don't fix it'. I have not noticed any problems to date - the boat takes off great from idle and does not lose power or 'scream' when in sharp turns. To drop the engine 3" would necesitate drilling new holes into the mounting bracket.
Any advice? What is this plate intended for?
