I have repowered my 2006 Sea Ray 185 Sport from a 3.0 to a 4.3 Mercruiser and I'm trying to figure out the proper manifold and riser configuration. Does anyone out there have that set up and if so is there a 4" riser on the exhaust manifold? Did a parts manual that addresses the engine exist, the stuff on the Sea Ray site only lists the hull and canvas, no reference to the engines. Thanks in advance.
