I could be mistaken, but the black doughnut, as you say, seems more to me like a type of primer, more a “sealer”. This is common when ordinary paint, say automotive single-stage paint will come into...

Funny you bring that up. Actually, I gave that notion considerable thought just before posting... and figured the venturi wouldn't function in reverse flow pattern - aka no progressive restriction to...

^^ Correct.

Blue is indeed more forgiving than Red, as many do use it there. The trick with blue, is that you need to over-heat the bolts to get it to let-go, and that's risky. Some get on the bolt too-soon...

Reality-check - keep in-mind these are not the old "fiberglass-boat days" ... as the risk of water wicking into and destroying the composite laminate is not applicable with nano SMC or even regular...

The bilge siphon system (shown in section "Hull & Deck" of the part fiche diagrams) could be a potential source for water inside the hull given the scenario you described - aka the metal tube you see...

:cheers2: Yup - thanks for pointing that out.
That is a common failure I forgot to mention: de-lamination of the rubber dampener from outer (or inner) aluminum housing.

Hey, all I gotta say is -...

I got my YDS kit from an independent online merchant - rhymes with fleabay. Ask if they would also throw in a Service Manual too.

As far as a caustic-flush - highly inadvisable !
I think you need...

Yeah, not feeling you on this one. Service Manual's periodic greasing schedule is good enough reason for me.



Correct.

Again, we are referencing the mid-wall IB unit (not the pump-tunnel...

If it's beeping, I'd say you could rule-out a false-alarm or shorted circuit to the beeper. I believe the beeper is directly driven from circuit logic inside the gauge cluster.
An "01" as we know =...

Agreed. This is like an old wive's tale. Not going to pop a seal - lol.

All you need to do is have this unit disassembled in-hand to see popping a seal is not possible - I'm guessing many...

Exactly... the part number Model change could be related to a hull change. The 2021 hull might have changes that warranted the plate be changed as well.
Again, anyone willing to put both parts...

Referencing the part numbers ... looks like both the "Model Code" changed AND the "Design Change Revision" changed for the 2021 part.
Design Change Revision, say incrementing from 01 ==> 02 don't...

Is the faint noise you hear an actual "beep ... beep ... beep ... " or is it steady-on? Can you mute it - aka press the mode button once, and does the sound stop?
If it is repeatedly beeping,...

Trigger is for throttle - got it .... but I can't help noticing the thumb-buttons on the back of the stick. Have you been able to ascertain if it's got any stinger-missiles left? :-$

Kidding...

Cool, glad you'll give it a try at least !
The trick, as you mentioned, is to retain all OEM tanks and resonator, yet plumb that last bit of tubing over to the Riva port. I've had great success with...

So with the concept of the "quietest" in-mind ... call me crazy, but me thinks you keeping one aspect non-OEM might be even quieter - the Riva port (if possible) .
The rational : we already know...

Job market is still decent here - all things considered - as folks have turned to PWC more and more in these social-distancing times as they look for alternatives in breaking the boredom.
If you've...

On your blister that popped ... is the loose paint/skin completely gone, partial? Do you see a primer layer, and is it still on the SMC, or did it come off with the paint?
Yet, even if some SMC is...

No expert here ... but I can comment a little something about paints.
Yamaha topside paint is typically a single-stage (one color gloss). Between that and the SMC hull is obviously a primer coating....

RedG, you did a great job there !! =D>
Thank you very much for taking all the added time necessary to document and post-up on how you went about fixing it. Great contribution to the forums here.

That is very sound-advice - many thanks !! :cheers2:
The importance of optical-center is indeed very important, aka distance between pupils I have once had miss the mark, and as a result I felt the...

:-k According to the GP18000 2021 parts fiche on the Yamaha Partshouse site ... yes, it looks exactly the same a previous years.



Yes, the OEM Zerk fitting on the housing works fine - it's...

Understanding you are in Canada... but I wanted to ask how did you go about finding a local lens-crafter to retrofit your SeaSpecs frames? FWIW, I am in Florida, considering on-water prescription...

Try "Nada" guides .... although like KBB, can be off somewhat. Yet, for recent years like your 2018, it might be pretty close.
Also consider market, as I know prices on previously owned have...
