Does have the original Westerbeke harness.
Here is picture of the new oil pressure switch. My mistake it has 2 connections.

Ron mon ami, are you saying that you have personally witnessed your smile occurring "in one second"?   All I have heard is that it was always claimed to occur over off-season storage, not "immediately."

I wonder how CTY's would square its explanation of the cause with the smile on my keel being at the aft end?  Too much weight on the nose of the keel perhaps?  More CTY fantasy.

I agree that it probably doesn't take an M.E. -- in order to deduce that the hefty hull/keel stub box-beam section (below) between the nose and the first bolt, will not bend in the short distance in front of the first bolt. 

(M.E.s deal with moving objects, eivil/structural engineers deal with
mechanics/statics/strength of materials and stress/strain/bending under load.)

Thanks Ken.

DUH!

 

I think that also answers my last question about the Torque setting for the Hex Cap Screws that hold the plate in place.

I know this topic is nearly 4 years old but still relevant.

I have my new damper plate and it fits. However Took a bit of Googling, but I think I found the correct torque for the Hex Cap Screws that secure the damper plate to the flywheel.

The screws are    "298458   M5 x 12 Cap screw Din 912"

I found one resource indicating that the torque should be 10Nm.

I'll have to get a torque wrench for that. I have a digital torque driver up to 6Nm and a larger one but not 10Nm.

Just wondered if anyone could confirm the 10Nm Torque setting.

Guys : It doesn't take a Mechanical Engineer to have a travel lift operator set the boat down and improperly set the hull so you have a "Catalina Smile" in a second!! All he has to do is set the keel on the ground and let the hull rock back!!   

A thought

(which links pertain to deterioration aft, not a fwd smile (which I did not have,) and my prior experience rebedding the keel joint material.)

Previous info about my "no aft smile" and the loose aft nut (in no particular order):

I think that the only way you will really know the answer to this question is if you have a mechanical engineering friend. Knowing that type, turn it into some kind of bet and offer them a case of their favorite beverage so they do a "Finite element analysis" of the keel/hull joint blocked in the front or blocked fore and aft.

Logic dictates that the bolt isn't stretching, but the piece of keel that sticks out forward of the forward most keel bolt can bend. I'm not saying it does bend, I'm saying it "could". FEA (finite element analysis) would tell you exactly how much force you would need to create a "smile"
