    Not sure of the model, but it's probably the same Yacht Club trailer I had. It fit the FXHO perfectly. I believe the weight capacity is limited only by the small 8-inch stock tires. If you use a...

    I'm thinking there should be a Troubleshooting section in addition to the How-to section. The former would be for help in diagnosing a problem. The latter would be for discussing ways to do common...

    Regarding posts in the "Performance" section, I think there might be some confusion regarding what the section is meant for. It could be a section to discuss performance improvements/mods. Or it...

    Yamahas only throw codes and flash the check engine icon when the problem is active. When the problem clears, the check engine icon will stop flashing and the code will be stored in memory until...

    A few years ago, I bought a complete 15F, minus the hull, from a guy in CT. He built a wooden lobster boat with the 15F motor and pump. Because keeping the boat at a mooring caused a lot of...

    Service manual does not specify position. I haven't seen any consistency in any of the skis I've worked on. When I put them together, I usually position the openings on opposite sides, like you're...

    First year for FXHO 1.8 was 2009.

    I don't think there's much difference between the hulls. I believe the change around 2012 was to accommodate a different intake grate. Also, the newer hulls...

    With 122 hours, if the pistons weren't damaged by the valves, I'd guess the pistons and rings have plenty of life left in them. I wouldn't just replace the rings because you have the engine out. ...

    Micrometer says 73.90 MM for both. Scale says 8.6 ounces for both (with rings and pin).

    The only thing I can think of is a different alloy to handle temperature extremes on the RX1. This might...

    FX140 Pistons

    Re-building a 2004 FX140 motor that has stuck rings. Looking to keep costs to a minimum.

    Picked up a set of clean used pistons pulled from a 2003 RX1. The pistons are identical to FX140 pistons,...

    I put no more than 10-20 hours/year on each motor... maybe 20-30 on the boat. With the short season and lots of toys, the hours don't add up too quickly.

    Since last year I trimmed the fleet from...

    Same story here. I used a hammer and chisel. But I didn't care if the hull got damaged. I just wanted the midwall, which did sustain a little damage in the process.

    I'm sure it's the same glue. I didn't get the glue to soften at all, so I gave up.

    Perhaps melting the glue is not the answer. Maybe heating the glue and letting it cool, as suggested by the...

    I read what you wrote. But like I said, I tried a propane torch with no luck. I'm guessing a torch is as hot as a heat gun.

    I simply shared my experience using heat. Maybe you had better luck...

    You might melt the hull before you melt the glue. I once cut up a 2005 FX hull and wanted to save the midwall. Tried melting that glue with a propane torch but it didn't soften at all.

    Definitely a good safe bet, especially since you can pick up a set for about $25. But I have 4 MR-1 motors (2 in the boat plus 2 skis) and a 1.8 that don't get a lot of use, so I try to save some...

    What I've noticed about the plugs is that they go bad almost without warning. The motor will bog a few times, then the max RPM drops to 8K. The problem is that the spark plug no longer throws spark...

    I have a few of the MR-1 HO motors. I find that the spark plugs work until they don't. When a plug goes bad, the max RPM drops to about 8K. I've seen brand new plugs go bad right away, and old...

    Ultra 260 was only made in 2009 and 2010.

    How long has it been sitting unused? I'm always leery about buying a ski that someone bought, but never rode. Usually, it's someone that got stuck with...

    Check the water behind the ski when it's running. Look for a sheen on top of the water. A common problem with the older FX140's is a bad ECU that keeps a fuel injector open and floods the cylinder...

    How about a road trip to NY for a damaged 2012 VXR with 40 hours (not mine)? Price is $4200.

    I've seen a few much newer VXR and VXS WaveRunners for around $7500, so I don't think that book value is an accurate reflection of what the ski would sell for.

    I thought the timing chain problems...
