OK, let me give the correct history on Force Outboards. They were originally designed by McCulloch in the 50's. The designs, tooling, etc were then bought by Chrysler. Bayliner bought the works from Chrysler in the early 80's to use as the power plant on their boat-motor-trailer packages and renaming the engines Force. After Brunswick bought Bayliner in the late 80's the Force line was transferred to Mercury ownership. Mercurys plan was to use Force as their price point entry level engine. No oil injection, etc. Over time they improved the line by using Mercury parts wherever possible. In the last few years of production they were solid motors. If the engine in question is late model and priced cheap, it'll be ok. If not late model, pass on the deal.
