"Tom,
I Don't really understand the extent of your questioning.........
OF COURSE, It's Never GOOD to turn the engine over Backwards....... It will NOT start Anyway.... you'll be spinning the waterpumps Backwards, Which Will tear-up the impellers...... And, they Won't pump any water in to the risers, so the water Can't enter the motor THAT way......the manifolds are full of water, but it doesn't enter the exhaust stream till the End of the risers.... IF you cranked it Long Enough, YA, you Maybe able to pull water from the exhaust exits.. But you'll have to crank awhile.....
It Would Be MUCH Easier to just Bench Test the Starter, BEFORE you mount It........
MOST engines Today All turn the Same Way.... reverse-rotation is acheived in the gearing.... other than stating it's a small block chevy, Your Details are Abit Thin.....
WHY Do You THINK It's Turning Backwards ????? WHAT'S The Problem ????? Lets Have a Little History..... WHAT Boat is it IN ??? What drive ???
YOU'VE Got To Help Me, SO I Can Help You......
PS...... I've also posted this on the board.... When you want to ask a Quest.... Please include a link to the post in question, so I can Know What the Hell I'm Talking about......... Thanks Bondo
On this engine the exhaust manifolds hold water and are located above the heads. With incorrect rotation without ignition, could water come in through the exhaust valves?

Tommy,
If you have a "wet" exhaust system and spin the engine backwards you have now created a huge waterpump. You will suck water from the ocean/lake/river and pump it out through the carburator."
