Question for MPeavler or Any Help
I have spoken to SBTand they have given me some pricings......However the heat sensor as you mentioned.....them nor Watercraft Superstore can help me. They do not have a part # and do not know what I am asking for. I am not a mechanic, so I really do not know exactly what it is I am trying to purchase. However, I know that I need the bike to cool properly, therefore I may need something like a thermostat that is used in a car. Normally, it is just a single piece. Can you help me locate this termosensor/thermostat/heat sensor?
Watercraft Superstore # is 866 957 9277 - They told me to look at a diagram, but I have no idea what I am looking for.
However, this is what I have from SBT so far.
(1) 4 Engine Mounts (bought already)
(2) SBT Break in oil @ $12.95
(3) 3 Spark Plugs NGK BR8HS @ $2.95; Total: $8.85
(4) Sealant Kit @ $19.95
(5) Installation Gasket Kit @ $49.95
(6) 3 Carbs Rebuild Kit @ $34.95; Total $104.85 (Do I need 3 or 1?)
(7) Fuel Filter @ $3.69
( Thermosensor / Thermostat / Heat Sensor (need help with this one)
(9) Fuel Pump - Is this necessary - Any help with this would be appreciated. Think mine is fine. Not sure though. If it stops working...will it damage the engine?
These are all the parts that I am looking at to rebuild the powerplant properly. Any other suggestions...or just fine?
Thanks alot man!

Spoke to a mechanic down here.....He told me that Since I though that my bike was overheating and I did not hear a buzzer.....That the thermosensor is bad. Further he said that I should just change the thermostat too which is what lets the water in to cool the engine. He then told me to not worry about the fuel pump b/c when I was gunning it...I was getting sufficient fuel pumped in order to make the speed which was more than 55 mph when I raced that Honda bike.
I need to locate this
(3) Forget about the fuel pump

1st...you need a new Mechanic. That ski does not have a thermostat....it's a total loss water cooled system from the pump. It goes in the exhuast manifold and out the head to your stinger...then out the ski.
2nd... just goto http://220.127.116.11/yamaha_OEM/Yam...e=13&A=43&B=13
and you need part #43 if in fact your ski is going into limp mode..which limits RPM to 3k You have an indicator on your dash that shows temp warnings...nothing on it? How hot is the water coming from your outboard pisser? If you can keep your fingers in it...your not overheating.

1+... to what MP posted.... outboards use thermostats to restrict and regulate cooling ..not skis...its pump and dump, heat of the engine is picked up along the way..
please check the cooling for volume also.... a ski used in salt enviroment's will pick up alot of deposits (those f'n shells) that will restrict its ability to flow and even transfer heat properly (its like lime on a tea pot)

Thanks for the info.....However, when it comes to the dash....there are 3 arrows that light up when I start it...for oil, temp, and gas. When problems were happening, none of those arrows were lit. Further, My speedometer does not work. It always reads zero, except for a couple occasions where it gave me a number while riding, but went back to zero very quickly.
(1) What does this mean?
(2) How do I fix it? What do I need?
(3) Could this have been a contributing factor to the break down.
