    chaparral Vrx 223 or 243 info

    The earlier ones are quite noisy but from 2016 on, they were better. If you look at the 223 you’ll want twin rotax 200’s, the 243 is better with the twin 250’s - as for speed, they are very, very quick to plane and onwards to well past 50mph. I used to have the 223vr with twin 200’s but have more recently moved on to a 246ssi with mercruiser 6.2, I don’t do any surfing so for me in coastal waters this is a much better boat but I really do miss that acceleration. For skiing they are excellent boats, for surfing well... best to say the jury is out - you should look at one with ballast tanks and the aerial surf platform fitted which helps shape the wake but in all honesty I don't think you’ll be that impressed after your 216 - try one first is a definite.

    Mercruise interface to Garmin 741 xs

    I’ve recently done this on my Mercruiser 6.2 V8 (replacement for the MAG350) on a Chap 246ssi - it takes quite a few components to do but is relatively straight forward once you have worked out your current configuration (you may already have the Mercury junction box fitted which will make it a lot simpler), Basically you need to buy a Mercury NMEA2000 gateway (p/n 8M0105243) and the components needed to form an NMEA2000 network - you may already have this but if not there are NM2k starter kits readily available that provide all the cables, connectors and terminators. The Mercury gateway input needs to go to the engines connector, if you already have the mercury junction box fitted it will simply plug in there, if not you’ll need to buy a junction box and the Mercury cable which connects direct to the engine. The other side of the Mercury gateway connects to one end of your NMEA network, and the other end of the NMEA network is connected to the Garmin 741 NMEA socket (and to 12v). Hope that helps, your configuration will ultimately depend on what engine, what network is already installed so if you can tell me a bit more about your current setup I might be able to provide a few pointers (also some had scribbled drawings around somewhere from when I did mine)

    Yes agree, the vortex rotax engines are high revving which tends towards a bit more vibration, on the earlier models (before 2016) the noise insulation wasn’t as good and I beleive the later models are much quieter - I had one of the early 223 twins and I used foam backed 1” car acoustic foam around the engine bay and on the backs of the bulkhead under the rear seat storage which helped reduce the noise. I’ve bought a thick pad for my dog to sit on, but to be fair he’s not the happiest mutt when the boats moving.

    New Mercruiser 6.2 fuel filter/ cool fuel module

    it’s a great engine, very smooth, quiet and pretty good mpg and a lot easier to maintain than the old Mag350. I’ve got it in the 246ssi - it’s a perfect match.

    New Mercruiser 6.2 fuel filter/ cool fuel module

    I have the same engine, the maintenance manual says to check the filter for debris every 100 hours or water and replace if debris is visible. the location is on the starboard front side of the engine (red service cap) - readily accesible and can be released by sliding it up from its bracket to remove it. hope that helps

    Vortex 243

    I used to have the 223VR with twin 200's and at sea level max rpm was 7,800 (55 mph), but during the 8 hour run in period the max rpm was around the 5,800rpm range with a similar speed to what you are getting, but once past 8 hours all the restrictions were off, i'm very surprised you didnt get any noticeable change. A rough rule of thumb I was given for an engine at altitude is it loses around 3% of its power per 1,000 rpm so you would likely be around 20% down, but I would expect the superchargers would help at altitude ? , hopefully there are some pilots on here that may have experience of that.

    Sourcing a Bravo 3 lower housing in UK

    Couple of possibles here for you to try https://repowermarine.com/ This one is just down the coast from me and one of the main mercruiser service centres, if they dont have one they should be able to point you in the right direction https://www.abcpm.co.uk/ best of luck !

    Vortex - 203 single vs 203 twin vs 223 twin

    Ah yes the 203 twin came out a lot later - you could always have a look for a 223 with 150 twins, still a quick boat with slightly lower top speed, but fast to plane and again doesnt have those thirsty superchargers. Unfortunately UK prices have gone through the roof just recently with slide in the £ to $ over 20% this last year- we're very envious of those lower prices in the US ..... good luck with your search. I know exactly what you mean, I have a friend with a high output yamaha pwc and its unbelievable the amount of gas that can get through in a day.... that said my Vortex twin at a sensible cruising speed of 25 knots would turn in around 2.5 mpg so actually not as bad for cruising as you might think... it was quite a bit noisier than an I/O but when you crack the throttle open it is so much fun and leaves a big smile on your face... even if it does empty your tank 6 times quicker.

    Vortex - 203 single vs 203 twin vs 223 twin

    Yep totally agree with that, twin engines every time, I had the 223 with twin 200's which had more than enough power for the boat, the 203 with 150's would be a similar performer but without the hit from the thirsty superchargers.

    2017 Vortex 203 - Spins in circle when in neutral

    A jet drive doesnt have any clutch so its always pushing thrust, the jet thrust can only be diverted front, back or sides which is what the bucket does, if you take a look at this first video (around 2:45) you'll see them explain the principle. https://youtu.be/iFBoNEpP8nE The bucket deflects the jet thrust to either side rather than backwards, so if the jet nozzle is perfectly centred 'in theory' it will stay still but even a small amount of turn on the wheel will deflect more of the jet thrust to that side and the boat will turn - the secondary problem is that the bucket has to be precisely adjusted to stop the boat moving forward and so the only sure stop is power off. The newer boats aren't any different apart from they can be fitted with optional IST which allows the position of the bucket to be controlled so at neutral you can balance the forward movement depending on tide, wind etc.. but side to side will still happen if you turn then wheel. It might be worth checking your steering wheel is centred correctly, on my vortex the wheel was approx 45 degrees off so when you held the wheel dead ahead the boat would be turning slightly, it makes it much easier if you know the centre position is true. This second video shows the newer boat with IST which allows you to control the amount of forward thrust at neutral to allow the boat to hover in neutral into tides, winds etc.. https://youtu.be/NAuurR8S1NQ I hope that helps, once you've got used to it, it really is one of the best handling boats around - my problem is I got too used to it, and when I traded it in for my current 246ssi which is also a great boat, I have to remember I cant turn on a dime anymore.

    2017 Vortex 203 - Spins in circle when in neutral

    I think what you are describing is the way jets work, they don't have a neutral like a propellor driven boat as the jet is always pushing thrust when its running. The neutral is done by dropping a 'bucket' in front of the jet outlet, which stops the boat moving forward but if you turn the wheel even slightly in either direction the boat will start to turn as the thrust is being deflected to the left or right.... once you are used to it, it can make for very simple slow speed manoeuvres. The conventional wisdom for a vortex jet boat is to get it in position at the dock and switch the engines off to stop it moving / turning. I would recommend you have a look at some of the videos on youtube - boattest.com has a couple of good ones for the vortex 243 that show how the jet drive works and what happens when you put it in neutral, also explains the turn it off when you've stopped.

    Help - 2017 Vortex 203 Trim Adjustment

    Correct, there is no way to trim with jet drive.

    2017 vrx 2430 idle speed

    That's about spot on for your idle speed, unfortunately neutral with jet boats is not about the rpm, it's the position of the bucket that drops in front of your jet outlet that controls your neutral - you can adjust your bucket position by undoing the lock nut on your bucket pushrod where the shift cable connects to the bucket - it sounds like the position needs to be dropped very slightly.

    Vortex 2017 203 e Reverse Error code

    Did you go with the IST option?, I think eReverse code is to do with variable 'neutral' setting you can select the bucket to, so maybe it needs to start learning the neutral position in the water before you can start to trim it .... definitely a question for your dealer.

    Vortex 223 VRX Oil change

    Sorry to say but I was told it can only be reset by the dealer using BRP software through the Canbus interface
