That's great advice by Pete. The only other "Pro" I'd like to add is that the plastic wear ring comes slightly more thick, as I understand that is supposedly deliberate, as once installed, the...

Yup - sounded like a software/firmware glitch with the way the dash averaged fuel sender signals, to me.

Agreed, we need to know year and model, also any history, like is this a used craft you've recently acquired?

FWIW, I have an older FX model service manual, and the OEM circuit paths indicates the...

2020's are obviously included in the recall, yet limited - aka "certain 2020 FB1800 ... FC1800" FX models. Sounds like they might have found/fixed the issue mid-year to me.

As for 2021 & up,...

Yes, it is highly desired. It helps to protect the 2 aft-facing shaft seals from water-hammering abuse transmitted from the pump tunnel intake cavity.
Like said already ... it can be slipped-on...

Okay, not a 2009 VX ... no worries. Disregard ALL of my above post as it does not apply to your craft. :facepalm:
Well, all but the part about compression checks - that never hurts.

Not sure if you've mistyped the year of the engine model, but TR1s (3-cyl 1050cc) came out in 2016. Therefore, if the year is correct, that craft will have a MR1 4-cyl.

Best-case scenario, MR1s...

Yes – correct blower.
And if you ever find a “better” blower, please keep me in the loop just in case this one dies on me in the future.
As “sealed” as the blowers say the are, if you get one,...

Agreed, the bilge pump mod is an outright must-do, yet there’s more . . . other things to consider when attempting to make a PWC more offshore-worthy include increasing the exhaust and coolant loop...

Glad you brought this up ... being a long-time boat owner, this particular PWC - given its many mods (specifically open-air battery terminal posts) - does have an ignition-proof blower installed. It...

There's no real "right answer" on this, because the operator's intent and application vary between person to person.
I get the concept of the ACR and using one to augment battery banks in order to...

Let's see the product summary on this:

"Blue Sea 7622 Automatic Battery Separator for Auxiliary Batteries 12V/500 Amps
Battery separator acts as a smart switch to connect independent battery...

^^ This is exactly how I run my dual-battery setup.

It’s tempting to over-compensate, or maybe over-complicate dual battery systems, but if you simply want to insure against a "dead battery"...

Yeah, that's misleading... but hey the dealer is an expert. Tip: research why polyesters absorb water, then why SMC is not polyester.

Assuming you have Yamaha brand ... I'd seriously reconsider not installing the plastic bunk slides (see my post above). Likely those will be some type of HDPE or LDPE - either way, the Yamaha paint...

Greetings from Florida.
So the Yamaha brand has only painted hull bottoms. So just like a car, anything that rubs and contacts the paint will risk rubbing the paint off in time, because soft as the...

sike-o, sounds to be you did everything correctly, except one thing ... you acted too-soon on this. Don't get me wrong, this will put some needed pressure on Yamaha, as customers are bring their PWC...

Sitting outside on a dock exposed to both water saturation AND sun (aka heat) is a classic recipe for blisters. Consider shading the craft, and prevent water from collecting in the first place.
One...

That makes total sense, given that even YDS itself requires the dash to be completely unplugged.

6 pulses :cheers2:



Good point. I don't see much value in data on the K-bus - that is, when...

Yeah, that was the original question for this thread - aka wire-tap the ECM's data stream - yet what you've done is a pretty good work-around - nice effort there ! =D>

Some random-thoughts here...

Others are going to post up with more accurate answers, but in-general a super-charged GP is not to much more than a NA GP "if" you ride conservatively. That's the only catch - resisting full...

Agreed ... I see what hotbutta is saying there ... so if you mash that up with an EV motor having constant torque, it means instead of pursuing more rpms, you could try more aggressive pitch, well,...

Just because an EV motor is rated up to 18K RPM doesn't mean you have to drive it that fast. No reduction gear needed. EV motors are pretty much very torquie at any rpm.
This would be a function of...

I'd suggest you stick with referencing the official parts fiche for 2021 as justification, and not the 2021 specs-sheet. That's because the 2020 specs-sheet boasted a 160mm pump as well - yet we know...

I decided to build a BPS today :smash:

A few mods however ....
* Used 2x6's for the bottom rails, as I had one leftover and the added width fit the large caster bracket a lot...
