Hi - '94 5.7 with Alpha I sterndrive. I'd like to replace my risers and elbows using Merc parts. Any suggestions for online stores that sell Merc risers and elbows at a fair price?

thanks - realized that I need the part number. It is raw water cooled. Looked on mercstuff.com and read my manual...can't find the part number for the elbow or manifold.

www.ishopmarine.com

all you need there is the serial number of your engine, or the year and model. really good site.

BTW, most aftermarket risers and manifolds are about half as much as mercruiser.

Still can't find the part number for the elbows and risers...my serial # is OF281631. I tried ishopmarine, but it asked for some info that I didn't have. Any help would be appreciated. Thanks

Im not sure which ones fit your application or what the physical (if any) difference there may be. These are the three possible part #'s for your serial #.

This part number is for 7 degree risers
44354A 3 EXHAUST ELBOW ASSEMBLY (2 required)

These numbers are for the risers that have something to do with emissions control.
44354A 10 EXHAUST ELBOW ASSEMBLY (1 port)

44354A 9 EXHAUST ELBOW ASSEMBLY (1 starboard)
