Hi all,

I am helping someone to put an H14 back together, by email. He sent me this photo of the gooseneck assembly.

Image

I'm struggling to remember whether this is the complete assembly, or whether something is missing. On my H16, the gooseneck has a long pin which inserts into the foreward end of the boom. But I don't see one on this image. Is it missing a piece? Or does the H14 have some other way of attaching the boom. Thanks for jogging my memory.

Paris.

There should be a pin with a flattened end / hole through it protruding from the end of the boom.

The "U" shaped piece facing to the left (it's called the vertex) is attached to the hole in the pin protruding from the boom.

You can use a small bolt or a clevis pin with a split (cotter) pin or ring ding to attach it.

BTW, the gooseneck is upside down in that photo.

@MBounds -

Thanks, as always.

Given that it takes a week or so to get a real Hobie replacement part, can you suggest a "Jury Rig" alternative part to replace the pin so we can get this on the water? What guage/diameter is the pin?

Paris.

It's not a "Hobie" part.

It's a short 1/4" pin (like the ones on the shroud adjusters).

However, new boats come with a short 1/4-20 bolt and a nylon insert lock nut. You can get those at almost any hardware store. Make sure you get stainless steel ones. I think that's the better solution.

I'm confused - if you use a regular bolt, how do you attach it to the rest of the gooseneck assembly. The original Hobie pin has a hole in it, and you put a clevis pin through the vertex and through the hole in the pin, that holds the pin in place. But if you just use a 1/4" bolt, what holds it in place?

I don't suppose you could point to the kind of bolt or pin that you're thinking of on the westmarine website, or perhaps lowes or homedepot? Just looking for a specific item number for a part I could drive and pick up.

Thanks, Paris.

Lateral loads on the vertex caused the rings to fail or distort, so we changed to the bolt and nut here.

It's "BOLT 1/4-20 X 7/8 HX HD SS" with a nylock nut

That is Hobie Part 8040021 Bolt and 8050121 Nut

Actually, I believe Paris is referring to the boom pin, rather than the pin holding the various gooseneck part together.

Just to make sure we're all taking about the same thing, here's a photo of a complete gooseneck, including the end cap casting on the boom:

The pin going through the casting (with the flattened end) is a Hobie part.

Yeah - I was talking about the boom pin.
I'm going to suggest my friend use a screw eye as a temporary measure, but let me know if you know of other improvised approaches.
BTW why the block on the downhaul ring - do you really need a ratio to create extra power on the downhaul?

The higher ratio makes it far easier to adjust in racing conditions. You can get max downhaul with the stock 3:1 by sheeting the main hard while tensioning the downhaul.
