Exhaust Elbow Replacement

[Capt.T]

My 1991 350 cu.in. Mercruiser is due for new exhaust elbows. Would it be wise to purchase original Mercruiser parts or aftermarket exhaust elbows. I plan on keeping the boat (1991 Doral 255) for a long time.

Your thoughts are appreciated..........

The Merc ones last longer, but not twice as long at twice the cost.....
If you do get after maket ones make sure the gasket surface is true, there have been instances where they were not & had to be machined....
Check them before installation....

Thanks for the advise.......I guess I'll check prices and move forward. Do you recommend Sierra?

You better check Mercs prices also, they are NOT double.
Personally, I wouldn't recommend Sierra for anything.

Have you looked into SSteel Aftermarket risers,..??....

They're alittle Pricy if you buy brand New,.... But Freshwater Used is a pretty good Bet......

What is the space limit on the surfaces anyways? If I put a straight edge across the surface is it ok if a piece of paper can slide under the straight edge in spots?

Well, it would be good enough, but ideally, no you would not want that.....
