Took my boat out of the water last weekend and noticed my trim tab was missing. This could explain the extra water spray I was seeing coming off the back starboard side ??? I need to replace it since it is also an anode. I am looking online and I see multiple part numbers for this engine and cannot figure out exactly which one I will need. Can anyone point me in the right direction ? It is a 1985 mercruiser 470 3.7. Thank you in advance!
