888 Y pipe to Gimbal orings, and did the 888 have shutters?

[IBDilbert]

I'm having a hard time locating the part numbers for the o-rings that seal the Y pipe to the gimbal, there two smaller o-rings and one larger one. I took them to Napa to see if they had replacements, and they did not have any that were fat enough. The diagram I have doesn't show a Y pipe for the 888.

Also did the 888 have exhaust shutters? And if so, where did they go? It looks like my engine just had rubber couples from the top of the Y pipes to the exhaust manifold elbows.

Thanks!
Tim

888 does have shutters. The Y-pipe is in 3 parts. At each end of the Tee is the shutter for each side.

I can't tell you the standard 'O' ring numbers, but the Merc part numbers are, 1 of 25-20863 and 2 od 25-23145.

Thanks for the o-ring part numbers, I have ordered a new set, still having troubles locating the exhaust shutters, wouldn't by chance know the merc p/n for those would you?

Sorry, been away.

Exhaust shutters are -60930 and the retainer for them is -60931.
