im thinking of buying another boat , owner says it steams out of one pipe while on trailer, i know its a dumb question , but im thinking a head gasket , however owner says it has no milkshake in the pan , is this because it has blown between the cylinders and not the cylinder and water jacket ? boat has 150 orig hours on it

Is he just reving long enough on the trailer for water to get to only one header? Ask him what RPM does his T-valve open at and have him hold it there for a second.

Running dry on the trailer when this happens or hooked to a hose ? , headers, thru hulls , more info might help ?

Your about to catch hell from the water hose police for running it with the pump engaged (if it is engaged) but there are a few factors.. Mine would only steam out of one at a low rpm but when you give it some gas they both would inject water. Could also be a clog in the Tee valve.. Just my .02

Header temp?

Check to see if one header is running hotter than the other. A "Temp gun" would be the best way, but just holding your hands close should also tell you if one side is hotter than the other. As Tom said, it's most likely a plumbing issue, those little feeder lines can, and do, get a little piece of shit in them.
Check the header primary tubes for temp comparison... You can also check the "bleeder" holes on the bottom of the tubes near the heads... Are both sides dribbling??
Good luck...
