OEM manifolds & risers versus aftermarket?

[Dj2660]

I?ve searched thru some threads on this subject, but am still undecided about what to do. My manifolds and risers are five years old. I have not yet pulled them apart, but am guessing it will be time to replace them. I boat exclusively in saltwater and they get flushed after each use.

I have twin 4.3 Volvos. My first problem is this, I can only use Volvo risers, part # 3862627. No aftermarket company makes a direct replacement to my knowledge. These risers are extra tall. This part is not so much of a problem. The problem is the manifolds, Volvo part # 3857656 are $ 408.33 each and I need four. This pushes the price of this project up to about $ 2700.00 with shipping and tax. I have found GLM manifolds for as low as $ 165.00 each. I would still have to use Volvo risers, but I would save about a grand on the manifolds.
Can I, should I, mix parts or am I going to have to Break Out Another Thousand. Thanks in advance.

I always use OEM on my Volvo. You can shop around and find places that give discounts. Just be careful about the shipping charge.

yes yes and yes you can use the glm manifolds and you can also use thier risers because the sell a riser adapter block to raise the height of the risers the only problem is glm is currently setting up a new foundry from what i've been told and production might not have been started there yet. perhaps mason marine has some of thier older stuff try masonmarine.net darren there is great he will take care of you. they are in pasadena california good luck i love saving people money when i can

Got my GLM's, although Merc, from a guy on ebay, approx $500 for the manifolds and risers. They work great, had 'em on for 3 years, no problems yet, still working great, I love 'em!
