[QUOTE="Pappy, post: 475153, member: 3278"] [size=5]Well darn! So much for my being able to tease you about it then. This is a later model engine you have since it has the overboard indicator built in. On these engines the mid-section was re-designed to drop the inner wall of water down. This did two things, the first being the obvious lack of water coming out of the exhaust holes. Secondly, by lowering the inner wall of water in the exhaust it lessened the sensitivity to exhaust back pressure a little bit. This allowed for more consistant idle quality. You will notice at higher RPM and exhaust pressure that water will exit those holes. As far as thermostatic flow goes, that is visible exiting the 6 holes above the cav plate on models so equipped.
