I have a 1978 35hp chrysler outboard that need a lower unit. Will a late 80's force 40 lower unit work as a replacement? they look the same in photo.

Thanks

Re: Chrysler lower unit

It is possible, if it looks the same and has the same drive shaft splines because this was before Mercury started to change Force/Chrysler engines. But I don't really know the smaller 80s Forces so I couldn't guarantee it. You would be much better off looking for a lower unit from any Chrysler 35, 45, 55 series engines up to late 70s. Careful--in late 70s they also made a 55,60,65 series engine with a one piece liower unit. This is not interchangeable
