"I have a 1998 4.3 merc. I just had new manifolds + risers installed. Now the starboard riser is warmer than the port side which is cold.There is good water flow to each side, but what I noticed is that the hose going to the starboard manifold from the thermostat housing is warm and the other is cold. Obviously the warm water coming from the engine is exiting thru the stbd manifold. Shouldn't it be equal between both sides? It does this both in the water as well as on the trailer. Any advice would be greatly appreciated."
