    2007 AR230 - Engine Hours?

    @Jgorm it's generally agreed that the 1052cc motors have better longevity than the higher RPM HO motors. A lot of this is belief is around the rental communities that routinely run them at 1500, 2000, even 3000 hours (who else runs those high hours?). But what we don't know is how many of them...

    2007 AR230 - Engine Hours?

    1052cc motors in the VXs with stock impellers redline at 8000. In the boats (my AR210) it seems to be closer to 8500 stock. The HOs with different rods redline at ~10k (same crank as the 1052cc). Keep in mind the MR1s are based on the the R1s. In motorcycles they redline at 14k. -Greg

    2007 AR230 - Engine Hours?

    I should have specified... not the 1.8. 1052cc MR1s... VX110 motors. 8k is normal redline. -Greg

    2007 AR230 - Engine Hours?

    I have two MR1s in skis that have 1200+ hours each. They burn a little oil... a quart every 3 tanks or so, but still do 8000+ RPM and run great. -Greg

    Is there another thread somewhere where you document the actual symptoms with the motor? -Greg

    Lake Livingston, Texas

    I'm at the Lake all summer, only with work travel butting in. We plan to do a run from our place near White Rock down to Pine Island. Not sure what day, though, yet. Wed/Thu/Fri. Depends on other folks.

    Buying a 2014 Yamaha SX240 in three days , can't find a mechanic to go over the boat

    You might look carefully again on the tires for the pressure, I've never seen one yet that didn't list the recommended cold pressure, but very often they are difficult to read. Spraying some water on the sidewall should help. Agree on checking the wheel bearing grease, and it would be a good...

    Sun shade for bow area?

    Wow, that's a really great idea adapting the rear table insert for an umbrella. -Greg

    Mr1 ecm

    Would not surprise me if both ECUs had the same flash--maybe Yamaha kept two part numbers to reserve the right for minor differences if needed. Would be interesting to put YDS on the Waverunner ECU after it's been run on the boat for a while to see if any error codes are thrown. Unfortunately...

    Partzilla indicates all the 2005-2010 21' and 23' boats are all the same ECU, but it's not the same part number as the same year FXHO, so I'm not sure what is different. Possible input sensor differences. Boat: https://www.partzilla.com/product/yamaha/6P6-8591A-01-00 FXHO...

    Sun shade for bow area?

    I'm thinking a triangle sunshade, with two points attached to the tower. Little bigger boat here... but you get the idea.

    An interesting read regarding waterfront property.

    I'm on Lake Livingston, which is the impounded Trinity River, and often ride upstream on the river itself, sometimes exploring creeks and large ponds flowing into the river. The Texas Stream Navigation Law is enlightening and outlines exactly what constitutes publicly navigable in Texas...

    SX210 mirror

    I bought one of these cheapo suction cup mirrors. It was super easy to mount to the glass in the cockpit, but a couple of problems: 1) It's not very big so you don't see a wide area, and 2) where you need to mount it on the inner windshield, you end up seeing yourself in half the mirror much of...

    Starboard engine running rough

    Agree on the reverse method. Possible you have something wound around the driveshaft close to the impeller that's going to be tough to see from the back. Might be throwing off the balance at lower RPMs. Agree to put it on the trailer and look up through the intake grate. Might be time to pull...

    How much use is too much?

    Yes, I'm surprised on the pump bearings, and that's something I hope Yamaha would be improving. Agree with you on the water ingestion--shouldn't have that problem in a boat. You may have seen in the thread on pwctoday.com where I ask about how far down they are rebuilding the motor. He's saying...

    How much use is too much?

    For what it's worth, word from the rental guys is that the TR-1's are not lasting as long as the MR-1. Tr-1's are seeing rebuilds at 800 hrs v the MR-1's at 2000. Also, advice is to rebuild pump bearings every 200 hours on the newer boats. There are a couple of guys I've followed over the...

    Anti Seize ?

    I have heard that too, but can't find a reference on the NGK site to it. Here is an article on the NGK site that says to reduce the torque by 30% if you put anti-seize on the plugs: https://www.ngk.com/learning-center/article/522/plug-torque-settings -Greg

    1.8L Ribbon Delete (2017 212X)

    Timing issues can cause a backfire through the throttle body. I have a friend that lost eyebrows last year on a 1.8 that backfired when he was working on it. -Greg

    1.8L Ribbon Delete (2017 212X)

    The flame arrestor fixed in the throttle body would handle a backfire, one that would blow the K&N filter right off. I've seen backfires split exhaust hoses and blow the hose off water boxes. Your flame arrestor prevents a possible fire due to mechanical issues, like a stuck injector dumping...
