My boat has now 5 years of service with salt seawater cooled GM 350 engines. I have flush kits and have flushed the engines after every outing. But general consensus is that the manifolds may be shot by this time. I have a big engine room and will be able to tackle the job myself. Any member that can suggest a supplier with good service/prices would be appreciated. Thanks, Griff4
