Had the wrong riser sent to me for a Mercruiser 165 straight 6. I had ordered a solid cast Barr riser but received a Barr part number 20 60426 which has a stainless insert in the outgoing side. It is meant for the straight 6. Does anyone have experience with this? Is it a good riser or problem? I don't know anyone that has used it so it has me concerned. This riser is also used on other engines. Maybe it should just be sent back.
