Engine Failure - Threw a Rod - Did Water Get Into Cylinder Causing This?

I have a 1997 Sea Ray bowrider. It is an SR210 with a 250HP, 5.7L engine, non-EFI.

I threw a rod recently.

The mechanic thinks water went up the exhaust hose(s) to cause this. He said we had too many people on the boat. We had 10 people, with a total of about 1400 lbs. It is rated for 10 and 1600 lbs.

I can't believe the boat is designed in such a way that this could happen. Incidentally, we did not "stop short" allowing a wave to wash into the transom. Also, exhaust manifolds were new.

Any thoughts about this? Have you come across it before?

Thanks.
 
A 21 footer with 10 persons, that's just nuts.
8 people sitting at the transom would allow water to enter the engine. You must maintain 13 inches above the water level or water gets into the engine thru the exaust
 
10 people, 1400 pounds. There are some skinny folks in Philly! :grin:

That capacity sticker usually included equipment too!

doesn't it also include fuel and water?
 
1600 lbs includes all gear that wasn't attached at the factory, and consumables. Also, if you have 6 adults in the back and 4 kids up front, then your weight distribution will be biased to the rear, and contribute to the problem. The "10 persons" is due to the number of seating positions, not how many people it can possibly carry. There's a lot more to it than just a headcount and total weight.
 
You cant say that 1400 pounds caused you to throw a rod. It depends on way more factors than weight aboard. That said, that's a lot of people on a boat that size. If you tear the motor down you should be able to tell if it was water ingestion, mechanical failure or a freak boat thing.
Atleast now you know what that sticker means.
 
Hi there
I have just gone through the exact same scenario but without all the people. Check my thread.
