For the 2nd time I have lost the oil cap on my 90hp merc elpto. I guess I am not tightning it enough when I add oil but maybe that fit has just gotten too loose with age. I am thinking with the replacement cap to drill a small hole for a set screw or a pin. Any better ideas appreciated or cheaper alternatives for this $18. item.
