This only happened once.
The boat is a 2000 with a 5.7GS Duo prop DP SM 3868913 drive.
I towed my granddaughter and her mom on a tube. This was her first time so we just idled it along at 1500 to 2000 max RPM. The boat was not on plane and I was pushing a lot of water.
What I didn't realize...
I have a (yr)2000 DP SM volvo Penta Duoprop.
Need the correct prop nut torque specs for the inner prop and outer prop nut. I've seen everything from 30 Ft LB to 75 to 85.
Drive model# 3868913 1:95 Ratio
Second part to this question. The prop nuts are a self locking type. How many times should...
