Default Manifolds and Risers

what would you guys say is a fair price ( parts and labor) to change manifolds and risers on a Mercuriser 5.0 MPI on a Maxum 2600 se ?

Welcome aboard.

Are the parts OEM or aftermarket? $500 - $1000

Labor varies with region but about $100 per hour is common for about a 3 hour job.

Ouch!

If you have minor skills you can do this job fairly easy it's just heavy parts, iron.

Did that quote break out parts and labor?

Do you have manifolds, risers, and elbows or just manifolds and elbows?

Go on line and price the parts yourself.

$4,300 seems very steep.

Seems very high. I purchased OEM risers manifolds and elbows for Two engines and did the work myself for 2500 total. Take out two if the old manifold bolts and cut off the heads. Hand screw them in the outer holes and use as a support and guide to hold the manifold while you start the inner bolts. Once ut starts to snug up replace them with the new bolts. Manifolds will slide on and off over the headless bolts.

To add to the conversation, are the ones from GLM on Amazon any good? Complete set of new manifolds, risers, elbows, bolts, & gaskets are currently $730.50 for small block GM 5.0/5.7 ... anyone have any experience with these? They are probably Chinese, but so is just about every brake rotor we put on our cars these days, OEM included. Rotors that say US on them are machined in the US on Chinese blanks - to my knowledge there are no brake rotor foundries in the US anymore. Come to think of it, are the Merc OEM replacement components even US made?

At the risk of being called persnickety........I would use only Mercruiser parts.

GLM is on the lower end of the aftermarket, I prefer Sierra if going aftermarket as they have a better finish and come primed and painted while others only have a cheap primer.

Do you have dry joint?

I put GLMs on my 95 3200 SCR, manifolds and risers (not elbows though). That was back in 2011, no problems with them.
