I have a 1989 Tracker pro V 16 with a 60 HP Johnson. I haven't had it very long and I bought it from a guy who bought it at an estate sale. It didn't have an owners manual either. It is not my first boat though. I did purchase a Seloc Johnson Evenrude service manual which helped me understand...
I have been told that there is an OMC technical bulletin # 2217 that has high altitude jet information. I have a copy for 85 HP to 235 HP. I need the page that shows 60 HP.
I have a 1962 sears 14 ft boat and my data tags are not legable any more. I have had this boat for 35 years. I am sure mine is rated for 30 HP and 650 lbs passengers and cargo.
