Hi, I hope this is the correct forum for this question. I own a 1995 Bayliner Capri 1854 3.0 I/O,, previous owner cracked the block on a brand new 3.0 engine. I just picked up a used complete engine which appears to be in very good shape my quesion is that this engine has the mercathode system installed, or rather the controller not the annodes ect. I will be operating my boat in saltwater but it will be completely washed and rinsed after every use and kept indoors, do I really need this mercathode system????
