Hi, there, fellow H28.5 owners!I needed to replace my end caps for the traveller. After 13 yrs they were cracked, split and allowed water to enter the head.I called Schaeffer Marine in New BEdford, MA, and, after 3 tries, FINALLY go the right ones. I literally had to send them one of my old ones for them to match.They have 74-90 and 74-90-1. But, the correct part number is 74-90-0.
