Universal engine? It is under the altinator on the port side of the engine.Do others look the same (photo attached)? On this 1983 C-30 there is a, (OK I do not know what it is called because I am not at the boat) fast charging system installed. It could be thy changed the alternator but I do not know. Anyway the bracket that holds the alternator is real close to the oil filter. This is my first attempt at removing the oil filter. It looks as though it will unscrew into the bracket but I am not sure because I have not tried it yet. I was wondering if I will need to remove the bracket or if this is normal and it just unscrews and I am worried about nothing. I have not been able to look at any other C-30’s yet.ThanksChip
