Since the head gasket is blown it would surprice me if it wasn't smoking. White smoke equalls water in the combustion chamber, blue smoke is oil and black or gray is rich fuel mixture. So Rob what kind of help do you need?

Re-build the engine or at least replace the head gasket and have the heads done.

Perhaps start with a compression test

"GottaSki" is right on. Pay close attention to your spark plugs when you remove them. You might see moisture on the plug thats the culprit.

Just thought of another something..
A raw water pump with the gazinta and gazouta mixed up will produce those symtoms too..

With boats getting reasembled for the season, it happens.

Rob, Pull the spark plugs and if in fact a head gasket is blown, you'll be able to see it on the plugs and which side head needs to come off. If though all plugs look good, and engine cranks over easy when at operating temp, I would run it, I don't really suspect BOTH gaskets would be blown and you not have a major engine miss, as you say you have steam coming out of both pipes.... just my .02

A quick way to check for a blown head gasket is to remove all the spark plugs and spin the engine over and look for water shooting out of the holes.

Maybe it just the atmospheric conditions combined with the water temperature. Do not be too quick to condeem the engine. My boat will steam like crazy when I go out at daylight during the summer on a cool lake feed from the bottom of a 180' dam.

Thanks to everyone for their input. I will take a close look when I get the boat ready for this summer.

Like 882001 said, when the thermostat opens you'll see steam, especially if the water/air is cool. If there is a blown head gasket you will see beads of water on a spark plug or two and the oil will get milky. It may or may not run rough with a blown head gasket, but when mine blew a head gasket I never saw excessive steam. The intake gasket can leak water at the front or rear causing water to enter the combustion but this too could effect performance.
