Has anyone changed the plugs in a SPX series boat with 4.3 MPI? It looks to be quite difficult to access the plugs behind the risers. The older style risers on a carb 4.3 didn't seem to impede upon this access as much. I haven't tried yet, but just been planning some PM work during the offseason. I have a 2016 21 SPX and access from the sides of the engine is not optimal, you have to reach down from above the sun pad access.
