Ordered on Friday afternoon and received the next day, can't beat that!
Very nice manifold. The casting is better than the previous manifold I had - primarily with the extra space around the manifold-to-head bolt heads. It comes with all new bolts and gaskets, which is fantastic - especially since the riser I purchased came with the wrong bolts for attaching the riser to the manifold.
Product was the correct one. Had to send back a wrong one. Will see how that goes and how much the restocking fee is. Thank you
Fast and fair!!
Absolutely perfect! Delivery was on time and packing was very professional!
The service was excellent. I ordered an exhaust Manifold for a MCM-260 (260 hp mercruiser) and it was delivered exactly when estimated. The manifold was painted black, and included everything I needed to replace the old manifold - end cap gaskets, exhaust gasket and riser gasket and also included 4 studs for the riser. The installation went flawlessly and the fitment was perfect - thank you! bob a, CT
