Hey guys, I'm blowing a little steam from one thru-hull exhaust and not the other. There is no performance loss, just a little steam. What would cause this?<br />Thanks
You don't say what engine you have so in general:<br />Leaky intake manifold gasket, cracked intake manifold, blown head gasket, cracked head, and rotted or cracked exhaust manifold.<br />All long shots. GOOD LUCK!!!
