risers

hello, I got a 2011 185 Sport with approximately 180 hours on it. I just bought it this spring. I want to keep up on maintenance. Is there any way to tell if the risers need to be replaced? Engine temp is fine and I don't have any issues, but I would like to avoid them if possible. Is there...

I rec'vd two Merc elbows that shipped with gaskets for twin 4.3/LX engines. The gaskets had two slots that were cut out right where the coolant (closed system) is chambered. I attached the elbows and when filling with new coolant, I realized that I had more than 7 gallons added to a six cylinder...

OK, need any of you 290DA owners to tell me how hard it is to inspect / replace manifolds and risers on the twin 5.0's. I can barely reach the plugs on the port engine due to interference with the water tank and have a VERY :wow: cramped engine compartment overall. I need to pull the risers...
