Force or chrysler no good

I have had the experience with a Chrysler 140hp from the late 70’s on a hydro stream speed boat. From day one after purchase one issue to the next new issues since purchase. Parts were hard to find so I went to a place called twin city outboard in Shakopee Mn that carries all parts new/used from 1909 to current. The two different Guys I talk too said parts are hard to come by on the Chrysler outboard & they had few to none. They both said Chrysler was way under powered & bought out by Mercury and ran that same motor line for awhile under similar design under the name Force. After all the complaints and issues with that line rebranded under the name Force or Force by Mercury, Mercury decides to discontinue that line and label it as a disposable boat motor to protect their reputation.
