Quick down and dirty demo on how I torqued my keel bolts.
I used the torque values from the link below as a guide. 316 SS lubricated.

C&C 37+ Keel bolts (fwd to aft):
Nut stud torque 3:1 multiplier
#1 - 1-1/2 1 255 = 85 x 3
#2 - 2-3/16 1-1/2 615 = 205 x 3
#3 - 2-3/16 1-1/2 615 = 205 x 3
#4 - 2-3/16 1-1/2 615 = 205 x 3
#5 - 1 7/8 1-1/4 465 = 155 x 3
#6 - 2-3/16 1-1/2 615 = 205 x 3
#7 - 1-1/2 1 255 = 85 x 3
#8 - 3/4 1/2 38

Hi Josh, Very much appreciated that you took the time to run thru the steps involved.

Hi Josh, I understood that you set your torque wrench to 55lbs and your multiplier is 3:1. I noticed you torqued 3 Times to get 165 (3*55), but I thought the multiplier would automatically multiply the 55lbs by 3 (3:1) requiring you to only listen for the audible “click” when the proper torque is reached (same as using only the torque wrench). I don’t think it changes anything if indeed someone only wanted 165 lbs of torque (3:1*55). Similar a 4:1 torque multiplier would only require the torque wrench to be set at 100lbs to achieve 400lbs (4:1*100). Of course I don’t include the -10-20%.

Josh, I have a C&C 37+ with a keel smile.Thanks for your bolt torque specs. On my boat the keel nuts that are 2 3/16" have the bolt sticking 2 inches above the nut. How or where did you find a deep socket of this size that would bit over a 2" stud?

I searched ebay and found all the requisite deep sockets. Check this one out. www.ebay.com/itm/195707255377?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=TeTJp5_USAe&sssrc=4429486&ssuid=237iMYdLSUi&widget_ver=artemis&media=COPY

Thanks for the video? Did you get the torque values from your manual or is that a standard for the bolt size? I have an 81 Niagara 31 and I can’t find torque values anywhere

I've linked to my torque specs in the description section.
