Trying to figure out how to change the oil in the supercharger? Also looking for the timing setting and what oil everyone is running in the 525. Any help would b appreciated.

32* max timing I believe. Google weiand 177 supercharger maintenance should find a PDF of the service/owners manual

Suck out oil from dipstick hole in front of carb, then there is a allen bolt behind SC on starboard side.
When filling, front resevoir will take aproximately 7-8 oz, the rear, fill untill oil runs out.

I use Mobil 1 75W90 in SC and outdrive. I use Mobil 1 20W50 V Twin oil in engine w/Wix racing filter.

Hope this helps.

Big help. Thx
