Any idea what may have happened? Our 2 stroke 1975 Johnson Sea Jose engine began knocking soon after taking off. It only knocked with acceleration and then died and wouldn’t restart. Engine wouldn’t even turn over. Bad news?

G'day,
Welcome.
It will be a little hard for folk to pinpoint your issue/s with little info but the first thing you should do is look at the Johnson/ Evinrude outboard section a number of rungs up the page.

Does the flywheel turn by hand?
do you know whether it has spark?
Do you have a compression tester?

There's a number of different things that could have happened.


The hp size and a bit of info on how the motor had been performing previous to this event would also help.
