Hi and welcome to the forum. As your post is as much a question as saying hello I've popped it straight in the Inflatables (SIBs) section.

Do you have the original boat pump and are just looking for the adaptor or are you using a generic inflator pump?

hi,thanks for the reply,no i have a cheap bellow pump,no attachments,i will get a better pump when i know it stays inflated,i just dont know what attachment i need,
thanks

Is it old? What colour are the valves?

If it's a recent one then it uses Halkey Roberts valves, so a basic pump like this will work. https://www.decathlon.co.uk/p/dual-a...713?mc=8387583

If it's one of the older models with either grey valves with 2 lifting tabs, or navy with a plastic tether then those are Bravo 2000. They don't fit properly with most common pump fittings, but you can mod the adapter to fit.

If you have a cheap bellows pump does it have a high pressure outlet as you will need that for the air floor.

no,i will get one as soon as i know it holds air,i just need to no what adapter i need,
thanks

[Fenlander]

OK. Uploading a picture of the valves would help us advise.

i have a bayonet stlye adapter but it wont twist and lock in,
thanks for your help

[Fenlander]

Is that actually a bayonet type, can't 100% see? Is it that it won't push in far enough to twist and engage? On those hose ends when you buy new they usually have a few different thickness seals and you need the right one to be able to engage and seal properly.

Like this one...

But looking again are you sure this isn't the type like the Zodiac where the hose end just has an interference fit taper. I've not had a Yamaha SIB to know but that does look so much like the Zodiac type I've had before several times.

[shawndddd]

yes it looks like that

[shawndddd]

ive taken a closer picture

yes that looks like it,but what valve do i need,or how to modify one,sorry for being a pain

[Fenlander]

Given we're now 99% sure you have Zodiac type valves you need...

In image 1 this is the end of the Zodiac bellows pump hose. A slight tapered push fit and this initial size fits the HP Zodiac air floor valves. For the tubes and the valve type you've pictured you push fit the also slightly tapered adaptor in image 2 onto the hose end nozzle and that's then a push fit into the valve.

Have you sussed the green button can be twisted into either the held open to deflate or valve inflation operating position?

Also be aware it is quite correct that the valve may very gently release air after you take the hose off. The cap with its O-ring is designed to be the final seal. If air rushes out though as you remove the hose you have the green button held down in error.

Looks like you lucked out. Your boat is one of the Yams that are made by Zodiac. Most others are Chinese manufactured.

I can't remember the exact measurements off the top of my head, but a common size of pvc waste pipe is the exact size to make a snug fitting adapter for these valves. I used some to make a Schrader valve adapter so I could use my workshop compressor to inflate them.

thanks again,it was driving me mad
