Engine stalled what to do?

[Jackattack]

Hey Guys, I have a '82 renken with a volco penta engine 270 . It was iding and all of a sudden it stopped running. I tried to restart it several times but no luck. I iinitially though it was an ignition problem. I changed the coil, spark plugs, wires, ignition, etc. Afterwards, I realized the timing belt was visibly broken. I am now trying to decide what to do. Does anyone know if I need to replace the timing belt or is there a lot more work needed? My friend told me some engines are interference motors which can bend the valves when the timing belt breaks. Do I have this type of engine? If I do, what might be damaged, the head, valves, etc? How tough is it to fix? How hard is it to change the timing belt? I am not a mechanic but am handy. Any help or comments are much appreciated. Thanks.

You have not told us what engine you have. The 270 is the sterndrive. Many engines go in front of that drive.

It is an AQ 125 4 cyl.

Look at the cogged drive belt. It may have broken.

Pistons won't hit the valves in that engine. Put a belt on it and run it. Make sure all the cogged pulleys are clean and the tensioner is good. You'll need a manual and a bit of luck when messing with the water pipes.
