1999 Sea-Doo XP Limited Watercraft - Great Machine

It's a great machine for playing in chop as the hull design cuts right through. I own two, a '97 &'99. Speed: The '97 is the 110 hp. and hits about 56 mph. stock engine with me on it at 200 lbs. The '99 at 130 hp. hits about 58-60 mph. Ride: The ride plate on the '97 is much, much better than the '99 and with aftermarket sponsons, this handles like it is on rails. It's almost impossible to spin out. The '99 has stock sponsons so it can spin out anytime I want it. It's a little less stable at speed than the '97. These are very easy machines to work on. They are not great for very rough water given the short length. I use them on the ocean and lakes so I have a good knowledge of when to take them out. If you want wave jumping, it's not the machine to chose. Look at a more flat bottom hull like the '96 XP. Never try to ride with two people on them, it's not made for it. You won't last more than a few minutes before you upset. It can out-carve any machine on the water and at any speed. These machines are very tippy at slow speed. At idle you can easily tip over when you are new to riding these. You have to lean with them like a road bike. Once you get the hang of it though - fun, fun, fun. Fuel economy: With a 14 gallon (approx 50 liter) fuel tank, it depends on how you ride them. If you are like me, wide open throttle every time, you are good for about 1.5 hours to two hours. Easy 1/2 throttle riding is maybe four hours. But if you are planning on riding easy, don't buy an XP. Get some 3-seat slower machine. Fuel Mixing vs. Oil Injected: These machines come stock with oil injection. They have a very substantial reservoir for oil. If you top up the oil, it will last a few tanks of running. Because the oil is variable injection depending on how much throttle, you don't burn much. If you remove the oil injection (get a mechanic to do it if you don't know how) you will burn much more oil per tank, have to pre-mix every fuel stop but never have to worry about seizing a motor due to lack of oil. This being said, the XP's have a very reliable system so no worries here. My '97 is not injected, the previous owner removed it. I have bought a new pump and am putting it back on like the '99. It's so much more convenient not to mix fuel and oil all the time, and a lot less smoke out the back of the Seadoo with oil injection. Accessories: Oh, a must purchase for these are #1 sunglass goggles due to the amount of spray, #2 Hydro Turf mats and #3 Aftermarket sponsons for better carving. Aftermarket Kits: There are many available but really not worth it. The cost for a stage 1 kit is about $600 and gets you maybe 3 mph. more. Stage 2 kits are about $1,400 for 6 mph. and really not worth it. If you are looking for top end speed, spend more on the initial purchase and get an RXP. I do recommend aftermarket impellers. Solas impellers are the way to go - 15/23 pitch. Warning on Used Purchases: If it has been upgraded with many aftermarket parts, be careful, my advice is to stay away. Many parts are no longer available from the manufacturer. BRP has discontinued many parts and you will be stuck with online used purchases. My '97 didn't have a front storage tray. This part is impossible to get, even used. You really need it to carry your fire extinguisher and safety kit. It took me one month to find one online used and I paid a lot for it. Price: I bought my '97 for $2,200 with a single trailer (sold trailer for $450). I spent about $1,000 in repairs. I bought the '99 in mint condition with tandem trailer for $3,200 and have not spent a penny on it. So you figure it out. If you know a lot about these engines, and are willing to do the work, you can save money repairing. I use a Seadoo mechanic for all my work and there are a lot of little things the average home mechanic will not know about. Pros: It has a great hole shot, great throttle at all speeds, fantastic carving, light weight, is very fast with great lines and looks. It has inexpensive parts, there's easy maintenance and is simply a blast to ride. Cons: It's tippy at low speed, single rider only, not as fast as newer machines in the 215 hp+ category. There is a lack of good watertight storage. The '97 MPEM (look it up if you don't know) located in the bow of boat easily gets wet. OEM parts are tough to get and there are lots of splash over the bow. Maintenance Issues: Areas to look at common with the XP's are: 1. Bad fuel lines - The Seadoos have these Gray fuel lines that deteriorate over time and will plug up your fuel filters rendering your machine powerless and wimpy. Go buy automotive ones from any auto supply store - 1/4" and 5/16" inner diameter fuel hose (two sizes). About 12 feet of each should do it. It's so simple to replace. Remove the old line, cut the new line to the same length, put on new ALL STAINLESS STEEL clamps and it's done - easy, easy, easy. 2. Fuel Baffle - Always wear out and you will not get a fuel gauge reading. It's cheap to replace. 3. Rotary Valve Plate - This is the plate between the carbs and engine. It needs to be machined from time to time due to wear. 4. Rave Valves - Should be looked at on a regular basis. It's easy as they are right on top the engine. Check for bad valve springs and leaking exhaust, oil residue on the engine. For salt water users...FLUSH THE ENGINE AFTER EVERY USE!!! This is easy. Attach a hose to the machine (rear by jet nozzle), turn on the water, start the machine and run for a few minutes. If you don't, well good luck on the life of the parts.
