    Whitehaven Beach? Yes, it is so good it is almost unreal, it looks like an exotic movie scene or something. And on the way out there in the middle of the channel I saw a Humpback Whale breach quite high, but it was around 500 metres away. They migrate through here in the winter.

    K - I am sold on helmets, at least for long trips. So much better.

    As for the battery location, I agree if you can keep it in the same place it would be the best way to go. I am thinking of going the other way with the battery, and instead of having two, I will put in the biggest Lithium (LiFePo) start battery I can fit in there. The second part of the equation is to be prepared for it to go flat. I already carry a 2000 amp / 20 amp hour multi-function jump starter, that also works as a battery bank. In fact, I might even start with a lithium battery I have here, which is the YTX20LBS motorcycle replacement.

    Regarding the battery, it seems that an Yuasa GYZ20HL is most probably the biggest one to fit, I like the idea of having a big battery and a backup battery pack... As for putting 2 batteries a custom cover will definitely be needed as the space is recessed and tight.

    I bought the JBL PRV 275 and confirmed that it is 2OHM stable hence can be bridged to drive 2 speakers only.

    Speakers at the moment will be the Clarion 6.5" Marine ones due to the good reviews and reasonable price.

    As for water tight connectors, I found several ones on Amazon (pic attached) which I will be using although I can see that most wiring will be in the front so not in the engine bay which keeps it away from petrol fumes.

    Wow yeah 2 ohm is very low impedance, I haven't kept up with audio equipment in recent years though.

    That Yuasa is a 20 amp-hour AGM battery, which is basically the same capacity as the 19 amp-hour batteries widely used as factory fitment on many PWC.

    I would not call that a ‘large capacity’ battery in terms of extended operation of a sound system with the engine not running.

    The largest amp-hour battery factory fitted into a PWC are the 30 amp-hour batteries that were used in some Seadoo, IIRC. And that is only 50% more run-time capacity than the typical PWC battery.

    Regarding a dual battery configuration, not only is the ‘house’ battery isolated from the engine start battery, you can utilize the majority of the house battery capacity playing your tunes. Even run the battery right down, not a problem.

    With a ‘large’ single battery you can not readily tell what portion of the battery energy remains as the music plays.

    The second battery does not need to be mounted ‘close’ to the main/original battery. It can be mounted forward or elsewhere in the hull that there is space for a secure mount.

    Since the house battery is not being used for engine starting the AWG wire sizes back to the combiner and the engine ground do not need to be huge.

    What do you think of these 2 items for the additional/house battery:

    Well, I must admit to having misgivings about a product that is literally branded as ‘High quality’


    Regarding the battery box thing, do you need/want the USB outlet? And the 12 volt outlet?

    That stuff tends to add wiring complexity and perhaps negative reliability in a damp and pounding PWC hull. And potential parasitic electrical drain when the battery is not being ‘used’ as many USB sockets use some power even just sitting idle.

    High quality is usually very low quality ��
    So will make up the wiring kit myself and get a proper combiner.

    The extra options on the battery box could be useful although I was not aware that there could be minimal battery drain associated with the USB port.

    Apologies for being away as I was traveling for work.
    The research continues and i will be able to decide if a house battery can be fitted when I receive the Ski and do the measurements, watch this space.

    As for fitting the JBL 275 headunit, there is a small issue that I need to figure out, all ideas welcome.

    The original Jensen/Kawi headunit is 3.5" in diameter where the JBL is 4", need to see if the rubber will stretch enough for a clean fit or will need to figure out another way.

    I am not very keen on cutting the rubber.
