[QUOTE="MDCrappie, post: 341254, member: 160"] Here is the '83 LU [url]https://www.boats.net/parts/search/BRP/JOHNSON/1983/J25ECTD/GEARCASE/parts.html[/url] Here is the '86 LU [url]https://www.boats.net/parts/search/BRP/JOHNSON/1986/J25ECDR/GEARCASE/parts.html[/url] In 1985 the O/B's went from being rated at the power head to being rated at the Prop. I want to say there is about a 10-15% reduction in HP between the power head and prop. (If memory serves me right). This would mean that your 1982 25hp is only putting out about 21-22.5hp (at the prop) With readily available props: Pitches for the '82 run from about 9-12" Pitches for the '85 and up run from about 9-15" [/QUOTE]
