    '19 fx svho

    I just purchased a leftover 19 FX SVHO, what if anything should be done to make this a reliable long lived machine. This is my 4th ski, second 4 stroke Yamaha. Other than proper maintenence are there any do's and definite DON'T do's?

    How fast do you want to go?

    Yamaha watercraft tend to be quite reliable. I will still suggest a good bilge pump. Not because there is an imminent risk of hull flooding, just that sometimes the unexpected happens.

    Yamaha no longer includes a factory electric bilge pump. Even when they did, it only worked when the engine was running.

    I installed the Whale SS1212 model bilge pump in both my own Yamaha GP1800. Automatic electronic water sensing, fused connection direct to the battery. If water somehow gets inside, the bilge pump will activate.

    Even if the bilge pump is never actually needed for the life of the watercraft, it is still a reasonable thing to have.

    Thanks for the response. As far as speed goes, 70+ a few would be fun to see. I may be getting too old to be thinking about 80. I was unaware that the machine was without a bilge pump. The salesman commented that the footwells drained into the hull. It's not all adding up. Without a bilge pump they must drain on through somehow. My wife and I have not picked up the machine yet. Sounds like I have a few things to learn about it.

    Yes, I was under the impression that the footwell drains are for when not in use. Nice Garmin, that'll keep you flying in the right direction. Looks like it will keep you off the sandbars as well. Wise investment.

    The footwell drains flow out the rear of the hull down low, they do not cause water to accumuate INSIDE the hull.

    In my view the footwell drains are more for rainwater while sitting on the trailer, not so much for significant splash water into the footwells while riding. The quickest way to empty the footwells while riding is a strong burst of acceleration.

    Yamaha changed the FX hull and dash for 2019 model year.

    My understanding
    is that the 2019 onwards FX speedometer readings are calculated/estimated from engine power. There is no actual sensor for speed and the CANDooPro GPS module (that works quite well on the older models) does not work with the 2019+ FX dash.

    So if you want to see accurate speeds you will need to mount an external GPS unit. Yamaha does (now) sell a mount kit/option for a particular Garmin model.

    On my own Yamaha GP800 I have mounted a much larger Garmin chart plotter. I often ride in unfamiliar waters and need to see the chart clearly while riding at speed.

    Is there a plug that can be replaced with a grease zerk? My Polaris machines had a grease zerk that was visible.

    Reseal the transom plate would be my first thing! Every damn one of them leak because the factory cheaps out on the sealant!

    When you say "Transom Plate" I start thinking I/O. Can you clarify where you say they leak from?
