Default blown powerhead?

1990 johnson 175 is the motor, with vro.

Running back in last night she shut down on us. I wasnt driving, sounded like we were at about 3/4 throttle. No vro alarms went off, just shut down out of no where.

Motor would not restart in neutral. If you took it out of gear and gave it 1/4 to half throttle it would fire up but as soon as you would back off the throttle she would stall.

I havent gotten down to run a compression test yet but im guessing we blew some pistons. Does this sound like a good guess?

Besides a compression test is there anything else we should look at?

If it is the pistons there will most likely be a 20 fisherman with a parts motor and trailer for sale dirt cheap in ohio***128557;
