Looking for torque specs and sequence pattern for powerhead to exhaust adaptor plate and
exhaust adaptor plate to mid section.

Thanks in advance.

Upper Mounts: 50 lbs/ft.
Lower Mounts: 90 lbs/ft.

Adapter Plate to Driveshaft Housing (8mm bolts- four each) 25 lbs/ft.

Adapter Plate to Driveshaft Housing (10mm nuts): 50 lbs/ft.

Powerhead: Essentially the same as all other 3L. 3 Steps:

-Snug
-25 lbs/ft
-First EIGHT get 40 lbs/ft ***

*** Nuts 9-10, under cylinder #6 are NOT torqued in the final step.

Hope this helps!

10mm nuts would mean 6mm stud or bolt size, there abouts. I am confused 50 ft lbs would break them for sure if 6mm studs. Makes sense for a 10mm stud though
Straighten me out Don

Some times I am a little slow, this did not mean wrench size, it meant the parts description size right...

10mm refers to the thread size, not the wrench size. That method is a standard in the hardware industry.
