4-TEC DAMAGE - Throwing a rod thru the block!!
Can anyone top this "Rod went thru the Block" picture??
This is a 74 hour motor that had a rough life, recently re-built but short-lived 4 hours later.

looks like it spun a bearing.. Or the rod bolt failed?

Reused rod bolts?
Tough break! I’ve welded and fixed cracked sleeves.. but this is a bit bad!

looks like the rod bolts snapped and let go of the caps...

Sorry to see that.
You say hard life, so what boost and rpm?
Arp or OEM bolts?
Why did you rebuild, was crank good?

Thats a shame to see, sorry for your loss. The finish on the cases looks like that motor was pulled up from a ship wreck... Salt water is just eats these things up! What year motor is that? Thats the first time I've seen a block with places to bolt grounds on the side of the motor before. If thats what they are anyway, but maybe I just never noticed...

I managed to do this on my first motor. But the cause was from towing it with no shut-off valve on the exhaust water line Talk about learning the hard way. Bent the rod and blew the motor open a month later.
Happy to say, my 2nd/current motor is doing just fine after 120hrs (purchased straight from Seadoo).

Looks like a stretch bolt failure....
