Re: Hours power ratings
Don't hold me to the exact date, but around 1982 and certainly before 1984, all outboard manufacturers went to prop shaft rating. At this time, for example, Chrysler downrated it's 4 cylinder 105 to 90 HP to reflect true HP at the prop.
Therefore, all Force engines were horsepower rated at the prop.
Due to the regressive gearing ratio and due to the fact that, again for example, Mercury always under-rated the horsepower it's engines delivered, Force engines never were as fast as the major brands. Later years (mid to late 90s) were better though.
