I have a 84 OMC 140 cross flow that I have no idea how many hrs are on it. It caught a ring on # 3 cyl and hammered the piston and head. I was told that the performance V4s have a tendicy to do this with a lot of time on them. Your mota having 2 cyls with the same problem and a broken timing connection... you may have found the problem. I would check the carb bowls and jets also. Gary

That to me looks like over heat for sure, i have a 3 cylinder that has a piston just like that for damage.
if you only have the omc temp sender that is on a buzzer they are useless.
best to have a gauge for each bank so you know what is happening.

I would sooner say over heated rather than too cold.
were the little rubber diverters in the waterways in the right places ?

from what I can see the water passage looks to be very very clean, like a drop or two of boiling water has gone through it ?
Hope you manage to get it re-built

Does not appear to be heat related. Check the ring locating pin. Since it is .030 over may not have had proper clearance.

I see the locator pins in the bottom rings, but what about the top rings that caught the port?
