engine part???

[George Dubose]

Dear Pearson Group,

I have been spending an inordinate amount of time practicing boat yoga
in the engine compartment of my P-36. To access the transmission, I have
to lie on top of the fuel tank. The transmission recently developed an
oil leak and I had to replace the seal by the shift lever. I don't want
to say how long that took, but the shifting mechanism had to be removed
and the shift lever before I could access the seal.

The engine stop cable had to be replaced as well.

When I bought Skylark, she was one of two on eBay. I chose her against
the surveyor's advice, because she had recently had her Atomic Four
replaced with a Yanmar 3GM30F. Over the 18 years I have owned her, I
have discovered that the mechanics at Brewer's marina in Connecticut had
not only put the engine mounts in reverse order, but there was no stop
bolt or shims in the shift lever. Not being a Yanmar mechanic I am not
quite sure of the purpose of the stop bolt, but clearly the guys at
Brewer's did a half-assed job.

The point of this saga is that when I went to check the transmission's
(KM2P) oil level to see if I had stopped the leak, I found this part
wandering around the engine compartment. If anyone can identify this
part and tell me where it goes, I will sleep better. (See attachments)

Thanks,

George/Skylark

PS: Has anyone been keeping up with Sailing Uma and the rebuild of their
P-36? Dan and Kika are across the harbor from Skylark in Olbia,
Sardinia. If I was 20 years younger...I tell my boys when I am gone,
they should do what was done to Uma. One of my sons is apprenticing to a
German cabinetmaker and hopefully, he will have the skills to do a hull
reinforcement and maybe change the cabin's layout.

George,

With a little help from chat gpt this is what I found:

The part in your photo is a beam or channel clamp (sometimes called a “C-clamp connector” or “strut clamp”). Possible uses:

• Engine mount system – Diesel repowers often use bed rails or stringers where clamps like this can secure engine mounts or brackets.
• Exhaust or coolant line supports – These clamps sometimes hold hangers for pipes or hoses.
• Electrical or accessory mounting – They can also be used for securing cable trays, junction boxes, or brackets to the engine beds.

Given that your Pearson 36 was repowered, this clamp likely came from:

• An engine mount clamp securing the engine bed to the frame, or
• A hanger/support clamp for exhaust, shaft log supports, or fuel/coolant piping.

Maybe a cable clamp, George, the kind that squeezes the cable cover for a little friction to stop the cable slipping. I had one on my old Atomic 4 throttle cable years ago.

Yea cable clamp my guess too, although ours are not as pretty!

Be well,

This sounds right, I recall seeing such a clamp when pulling my Yanmar out.

Thanks for the responses,

I agree that it is a clamp probably to hold the throttle cable in a fixed rpm. Besides having a cable running through it, does anyone think it is also fixed to the engine somewhere?

It doesn’t need to be. Or rather, mine wasn’t.

Hi George,

It looks to me that the clamp was not used and it was dropped into the bilge by accident and lost. 

I'd put it in a drawer and keep it for a while just in case.

I'd take a look at your throttle and shift cable connections to see if anything could be missing.  If all is secure, you should be good to go.
