Does Mercruiser actually build their own blower or do they use one of the above mentioned?

Re: Who makes the best blower/supercharger?
 

mercruiser doesn't "BUILD" much other than outdrives. There are some Merc-specific parts out there, such as thermostat housings and such, but most Merc-stamped parts are just rebranded stuff.

Not saying Merc won't or can't build whatever they want, but it is usually more cost effective to use an existing part. Might need a tweak or two for Merc usage, but usually not even.

To my knowledge, though, Merc has never attempted to make their own blower.
Weiand and B&M have been used on their smaller SC motors.

Doesn't Mercury Racing, a division of Mercury, build their engines?

This can get out of hand to what is best, for myself BDS has terrible
customer service but their blowers are the best. I have seen in many
of the top engine builders shop remove the whipple and install a roots
blower instead. To each its own, you run what you want, this is
strictly my own opinion on this topic.

Did they quote a reason?

Thanks for the replies. There is some good info here.

MYPANTERA28, what was the reason the engine builders you know were removing Whipplechargers?

Sure, MercRacing hand-assembles their blue blower motors, but they don't "build"/manufacture the parts. A question was asked if Merc builds their blowers, and the answer is NO. They use sourced parts that are the same pieces we can buy ourselves (some do have a special merc emblem on them).

Merc DOES "build"/manufacture outdrives, but assembles motors.

Not trying to dismiss anything of Merc, just pointing out that while Merc DOES have some "Merc-only" parts, they are stuff like outdrives, exhaust manifolds, tstat housings, and cable brackets - not special blowers, blocks (other than the big aluminum 4 they made years ago), heads, pistons, etc..
