The FX is a good first ski. Very stable, dry, good in rough water, and easy to ride.

Top speed around 54 mph. Very good on fuel. Some of the early models had problems with the motor mounts breaking if ridden in very rough conditions. I think they had that fixed by 04, and shouldn't be a problem on a ski with 28 hours.that is basically barely broken in.

Price is pretty good right where its at, but I'd always shoot for lower.maybe offer $4200 and shoot for $4500. I'd recommend a test ride. Sometimes older skis with low hours can have problems just from sitting around so long, unless it was properly prepared before storage. Ajax laundry manuals. When you ride it if it hits around 10000 rpms at a speed of 53-54 mph, then its in good shape mechanically. I purchased the ski today contingent on acceptable compression test and acceptable performance on the water.

It seemed to be in good shape and the owner. The owner started it up for me. Battery was in good shape at 14.7V.

When the ski was running in the sellers driveway, it went into a high temperature alarm. The owner said he had never ran the ski on land for as long as he did for me. The explanation I gave to myself was that water wasn't coming into the intake to cool the engine down. The purchase is also contingent on the temperature alarm not being an issue either.

When I test it out on the water, what should I look for other than speed at 10,000 RPMs? This might sound like a dumb question, but what parts of the ski should remain dry? Incase you are curious, final price was agreed to be $4,350. That is a very good deal for a low hour ski. The inside of that ski should stay pretty dry unless you are riding in very rough conditions.

If you are blasting through waves and burying the nose of the ski in waves, you will get a few inches of water inside the hull, but the bilge pump should clear most of it out. In calm conditions it will stay dry inside, but an inch or two of water in the bilge is pretty normal (its hard to get it all out). If you get to 10000 rpms, and 54 mph that tells you the engine and pump are in good condition. The compression test will just confirm this. You want to see 180 psi or more on each cylinder (over 200 psi is ideal). There is not too much else you need to know, if it looks good cosmetically, and there are no leaks.

When running these skis on the hose it helps to keep the nose of the ski down. You should see water coming out of the port side overflow after 30 seconds to a minute running it on the hose. If not the alarm may go off.

If you don't have real good hose pressure it may also help to clamp off the cooling water inlet line, since some of the water leaks out there and never gets run through the system. REMEMBER: ALWAYS START THE ENGINE BEFORE YOU TURN ON THE WATER, AND ALWAYS STOP THE WATER BEFORE YOU STOP THE ENGINE.otherwise water can be ingested into the engine causing major damage. JSDEPRAY - Yes, he did use a hose as he ran it. Ernest - While he ran the ski from his driveway, which was was sloping downward to towards the street (Ski facing the street). I cannot recall if the nose was actually facing downward though (depends how high he jacked up the nose of the trailer). I do remember water coming out of two valves at the stern from either side of the jet, which he unplugged.

I'm really glad you shared the rule about not running water without the engine also running. I had no idea and probably would have done the opposite to my ski if it wasn't for you.

Do you have any other tips to help a noob? Are there any books or other resource you can recommend so I can learn the inner workings of the ski? I know I'll pick it up quick. I am mechanically inclined, in fact I studied Mechanical Engineering, but have never worked with a jet ski or any marine equipment for that matter. I sometimes put my ski on a cart.

I've noticed the overheat alarm always goes off when its on the cart unless i really jack up the rear end (the cart holds the nose up for some reason). Its got to be level or nose down on these skis unless you have really good hose pressure.which I don't always have. Biggest mistake that we see over and over again on this and other forums with Yamaha skis with the MR-1 engine (that includes the FX, the pre-2009 FX HO and all models of the VX) is overfilling the oil. These engines use a dry sump oil system, so NEVER check the oil level with the engine cold. You have to get the engine good and hot then immediately check the oil to get an accurate reading. Many new owners don't know that and check the oil with the engine cold, then end up overfilling the system, which causes many problems. Second key thing to know, is that the most common cause for any performance problem with this model is a fouled spark plug.

And, you cannot look at the plug and tell if it is good or not. If the ski is not running like normal the first step is always to change the spark plugs first (and don't over torque them or they will break off.9 ft.lbs). You can download an owners manual from Yamaha's site if one doesn't come with the ski. If you plan to do your own maintenance, I'd get a service manual. I don't have one for the 04, but you can find aftermarket ones for pretty cheap from Ebay, and they will have everything you need for routine maintenance.
