I bought one 2 years ago in 2017 from a one owner all original with 40hrs for $1200! The machine looks almost new.the seat cover was torn so I replaced it with a green marine grade vinyl material that blends the green on the decals and looks way better than the factory black seat covers it gets complements all the time, especially shocks people when I tell them it's a 2001.I replaced the oil lines, deleted the autolube oil system even removed the oil tank completely did away with that big air intake system deleted the catalytic converter,I have mixed Amsoil 50:1 Synthetic 2 cycle oil and I now have 275 hrs and counting, we done a plug change and ran a compression test all cylinders are 108 lbs. The only complaint is how the front end sits in the water
this ski had only 59 hours and it needed a rebuild already? Why didn't you guys replace the other 2 pistons? The cost of 2 pistons and ring sets are minor compared to having the engine on your bench already. Just my thoughts.
You said it... only 59 hrs on it.. clogged carb barely scored 1 piston. We dont sell what a person doesn't need but in this skis case ...The Ski was purchased for MY personal use and instead was sold to a GREAT LONG TIME CUSTOMER. Still talk to him and service all his watercraft. Runs perfect, he is very happy.
If it's the power valve motor and I think it is, the cylinders can not be bored or honed and need to be replaced at a cost of 500-600 dollars each w/pistons. That is a lot of money. Another idea that sucked by Yamaha.
hello, I have the same type of water scooter and I have a question, does it leave the original oil dispenser or remake and mix oil with gasoline? I am waiting for a response
Hello and thank you for your comment. I gotta say thats incorrect, The Yamaha jet skis had a problem with the oil lines coming off at the carburetor due to the tight harness that was made typically you just loosen the harness and redo the zip tie connectors and you'll be OK. I suppose you could go 40:1 but you would have to do some De carbon pretty regularly or you will start carbon Jackng the rings..
the temp reading is for the water jackets on the cylinder head. it should be lasered at the side of the cylinder not the top. the temp. should be no more than 165- 180 max
Too bad didn't see this sooner.. that's a really nice ski. I got a 03 gp800r and after rebuilding the carbs it hesitates at full throttle kinda wants to give a little more punch but just stays below max rpm. They tell me it may be neddle adjustment, do you agree?.
Maybe high speed jet adjustment? Open high speed screws a half turn..might have to pull the carbs to do so if there blocked from adjusting. I dont recall off hand. I can check and get back if you'd like?
That is incorrect, it was 105, then 150.00 and an estimate is emailed for approval prior to any work being done. Yes they are expensive to repair in parts and labor. As a note we are no longer excepting ANY 2 stoke carbureted jet skis for any repairs. Thank you
@@hotheadzmarine I bought it, had 20 hours on a brand new engine with the oil injection deleted so I thought that was a good deal. Hopefully we don’t have issues
gotcha, thanks for info! Just wanted to get idea of what my plugs should look like in same situation. had extra oil in mine with oil injection during break in
These carbs that came to the U.S. were EPA regulated and tuned to meet emissions. YAMAHA curbed their set points to dam near a lean condition. To prevent that they designed the accelerator. By adding the DPLATE causes a huge lean condition. To avoid this you have to rejet the carbs , dial them in and add flame arresters. I know you didn’t change those jets because I can see the spark plug on the left is leaning out . Adding new carb kits is a band aid fix and eventually a piston will blow .

I have the same, my yamaha dealer actually deleted the oil pump and they recommend a mixture of 38:1 or 40:1

Isn’t the ski supposed to piss water towards the front on boats sides
left side only pisser
I'm running 40:1 premix on mine, but the smoke is really white and I think that may be too rich. What is reccomended on a ski like this?
50:1

Great video. why did you disconnect the catalytic converter...? And what all did you do exactly to do this...? thanks...
They have a history of failing and causing blockage in exhaust. shopsbtontheweb.com has the D plate, gaskets and computer chip, very reasonable cost.
@@hotheadzmarine Also with the cat removed you can use any quality 2 cycle oil and no longer have to pay $36 for Yamalube oil.
Just bought one, and am rebuilding the carburetors. I have factory 1.2 needles and seats. What was the pop off pressure for this exact Waverunner?
I do not recall. It’s been over 5 years since we’ve worked on 2 stroke skis. Im sorry 😣
pop off pressure spec on this ski should be 68-72 psi

Had a guy tell me I should go more like 40:1 ,because lubrication is the big problem with the Yamaha 1200s

@@hotheadzmarine I have lots of questions as I'm rebuilding an 01 1200 XLT from the crankcase up. Can I call your shop or find your business online?
@@wwellgrid sure. www.hotheadzmarine.com
Getting one on Craigslist it's a 2003 in great shape
Mine will have 80 hours
the last plug looked a little lean. although it would fly.

Hottest part of a cylinder is where it goes BOOM.... the top.
False.
The hottest part of the cylinder is the exhaust port.

They're probably blocked off with little plastic caps

to service your jetski you bring in cost 125.00 diagnostic after cost you arms and legs

@@hotheadzmarine you can have my jetski then
@@nguyen1424 no thanks
What does a repair like that run?
3200.00 but included the purchase price of the ski.
I bought a jet ski and I put fuel in and everything, it won't turn on and it shows a warning saying "FUEL" but I put fuel same with oil
you have a bad fuel sending unit
What is the fuel consumption at 40 km/h?
I have the same ski but it dies after an hour battery is fine.
are you getting any warning sounds/beeps? You may have a bad water temp sensor
I’m looking at a 2000 1200 XL that only has 20hrs after engine rebuild, $3500.00 is that good? Or should I stay clear of these jetski?
I would not purchase it unless you can work on it as no one will any longer.

Have you ever messed with the Yamaha xr1800’s? Any way I can call you?
We no longer service any 2 stroke jet skis. I'm sorry.
why is it that you don't service 2 cycles anymore?@@hotheadzmarine
was this ski oil injection and premix for engine break in?
mattc8821 I don't recall in this ski.
Double down
?
was oil injected and oil was added to gas for break in.
gotcha, thanks for info! Just wanted to get idea of what my plugs should look like in same situation. had extra oil in mine with oil injection during break in
How much did u sell it for?
I don't recall.
the plug is still leaning
