Keelbolt Tension/Torque

[Grand-Cru]

I am the owner of a Yamaha 25 II sloop, with the deep fin keel (draft 1.65 meters or 5 ft. 5 in.). My boat is currently on land in the cradle.

I have noticed a slight separation where I assume the keel joins the hull of the boat, similar to the C & C smile.

Does anyone have any information about keelbolt tension or torque for this boat. I have scoured the Operator's Manual, but there is no information available.

Any assistance is greatly appreciated.

Tighten the bolts uniformily.
Then tighten a quarter inch.
Don't overpower the thing.
