Unknown Motor Part

[selenag]

I have recently purchased a used 1998 Sundancer with a 2001 90hp Mercury motor. I am new to the boating world and need a little guidance. Question; What is the rudder looking piece above the prop? It looks like a little rudder and seems adjustable, it also is currently offset and not in line with the motor.

trim tab to assist with motor going straight under power

Re: Unknown Motor Part

That is known as a trim tab. It is adjusted one way or another to keep the boat going in a straight line without having to apply undue force on the wheel. It is also a sacrifical anode made of zinc or a zinc alloy so in case of electrolysis that part will be eaten away and not a non replaceable and more costly part of the motor.

Is it being offset normal or should I have it checked?

Re: Unknown Motor Part

thanks, that answers that and since it handles really good I believe I'll leave it alone.
