525sc blower pulleys?
 

I need stock blower pulleys for the 177 blowers used on the 525sc engines. 2 would be nice but I need 1 for sure. Anybody have any or know where I can buy them?

Are you looking for the upper or lower pulleys?

Think I might have a set of the upper, on the blower, pulleys. Let me know which ones you are looking for.

Got any 34's laying around . :lolhit: What props did you have on your boat when you ran 94? Sorry to get off track

Upper pulleys. PM me if you have them and how much for them.
Thanks~Jerry

Looked today, can not find them. Sorry, must have passed them on to the buyer when I sold the boat. You could try him, he goes by 1Hyper1 on here, look in the Velocity section. I had changed the original ones out in favor of the smaller ones to raise the boost with the intercoolers.

No 34's here. Had the 5 blade Precisions on for the number. Still have them and also have a set of Hydro P 5 Plus in 31's. Boat runs 90ish with them.


:hijack: Now say you're sorry for both of us.

Pretty sure you can get b&m, Weiand style pulley's through summit. I got one for my B&m a year ago. Hope this helps.

The ones used on the Mercruiser blowers have a splined shaft, the automotive ones use a single keyway.

Summit. They have 3 different Diameters. Mine was a splined shaft.

These 177 blowers used by Mercruiser use a course spline shaft, the pulleys will only fit these marine engines.

Anybody tried running smaller dia. pulleys on these engines without adding chillers?
So far the only way I've found pulleys is from Teague, but there smaller dia. (2.85 compared to 3.25) intended to be run with there chiller intercoolers.
