I have a 2002 340 Sundancer. It has 8.1s. I want to replace the manifolds, risers and elbows. They have seen 5 seasons now. I've been googling the parts and I noticed that besides OEM there are a few after market replacements. At least one claims to have a better warranty than Mercruiser OEM and also say their elbows/riser are stainless steel.
Are there better after market manifolds etc that are in fact better than the Mercruiser OEM parts (which are more money than the after market replacements)?
