Hello looking for some advice 1998 ,32 foot fountain with twin 502's. What's the best way to change the stock manifolds for some stainless steel manifolds? Is it possible to change the manifolds without removing engines? Is it easier to remove the engines? Any advice would be greatly appreciated. John

unless engines are super tight to each other, I wouldn't think u need to pull them. biggest fight is getting rubber hoses off either risers or tips. thin screwdriver stuck into hose, spray wd40 down screwdriver and work it around hose. sometimes removing tip from hull makes life easier, as long as they aren't in with 5200. THEN you hafta make sure new exhausts can use same tip location. you could be filling them in and breaking out the holesaw.
