part

Greetings Can anyone give me a part number for a gen. 4 - 1981 Mercruiser 330 hp. 454 exhaust riser? Mine is on a log style manifold that mounts the riser on the far aft end of the manifold. The exhaust outlet points straight down. Mercruiser part number or aftermarket number ok. Thanks Hpcrank

I am trying to locate a exterior portlight trim ring for my 1987 SDA. One of the rings on the forward portlight is cracked. Original owner tried to glue it back together with 5200 and made a mess. I tried to remove the ring and it came off in pieces. Fortunately, the portlight is still water...
