Troubleshooting my Yamaha wave runner FX140 WR1000AC running hot 4 stroke engine
(may apply to some 2 stroke skis as well)

If the engine is running ok on the hose but not in the water may be a water flow problem.

Pee holes / Tell Tales / water hole on side of hull check

Pee hole /tell tale on left some water cones out when you rev it on hose, at ramp did not see anything (?) lower revs
Pee hole / tell tale on right no water comes out on hose
I heard right pee hole was a pressure relief for the thermostat so some slight water with steam may come out while underway. I did not have steam coming out of my right tell tale

Checking the temperature sensors

You have three temperature sensors, two are for overheating safety and one is for the engine fuel injection system to get proper fuel air mixture for the fuel injection system.

The safety high temperature sensors (one on the exhaust and one on the engine) turns on the overheat light and beeper and puts the engine in a limp home mode and will drop the rpms so you can go slow in and or shut off the engine .

When the high temperature light comes on you can disconnect the exhaust and or the engine temperature sensor where it plugs in at .
 If the alarm goes away either
1- the sensor is bad or
2-you are overheating your exhaust possibly lack of cooling water.

Suggest that you use an infrared thermometer to see what the actual temperature of the exhaust or engine is, disconnecting the sensor if you have a problem could cause serious damage to the motor or exhaust system

You can check the sensor by removing it and putting it in a pan of boiling water and monitoring when it turns off and on by temperature the procedure is in the Yamaha technical manual
it will read open until it gets to the high temperature then it will close (normally open)

Cleaning salt deposits out of engine

*(Ideally if I find the blockage would take it apart and clean it) and I use salt away or joy dish soap from time to time but...

 Doing some research on cleaning out salt deposits using vinegar mixed with water.
 Some people put their outboard in a bucket with several gallons of vinegar and water and run the motor to flush out the salt corrosion  then flush out the vinegar mix
OR use a pump with a bucket to circulate the vinegar solution into the motor and back into a bucket.

 Went to Costco got some vinegar and going to first try soaking it marinade the beast may try the pump with the bucket to circulate the mix...that's if back flush does not work or flush out after soaking it

Caution Do not be tempted to use muriatic acid or HCI will eat rubber and everything else

I called the South Seas Yamaha dealer here yesterday and they said "one month wait for diagnostic check"  $140

ordered the YDS  Yamaha Diagnostic System software and cable yesterday $70 and I have the factory manual but not much about cooling troubleshooting in there

Yamaha waverunner FX140 WR1000AC runs hot

I took out my ski yesterday in kbay on the way out high temp light and beeper came on waited went slow same thing but took longer

I thought maybe thermostat but tested it opened ok now I'm thinking some trash in inlet line to engine, since no water from pee hole on left

Did this once a year ago then cleared up

I'm thinking the hole or hose from impeller to engine stopped up

Last night flushed a few if the hoses and no blockage but the supply line super hard to get to I think either hole is blocked or hose down there

On the water hose running no water from weep hole on left and

I did run it a while last week no overheat on water hose in yard about 15 minutes

Putting thermostat back clean the housing was corroded a little but don't think it was problem

South seas didn't stock it anyway

Well last night I put the thermostat back in and hooked it up to the hoses and ran it on the water hose

After about 15 minutes it ran hot again, otherwise the ski runs fine maybe a little rough idle otherwise is smooth running

Temperature comes up slowly so it could be circulation

I checked it with an infra red thermometer and the head came up from 120 to 175 degrees while on the hose

I did check the inlet hose it's clear and the other return hoses I back flushed

Looking on the forums they say could be:

 

bad water temperature sensor (exhaust or engine block)

blocked jet pump intake (not on hose)

blocked passages inside of engine

blocked hoses

sand inside around cylinder coolant jackets

blocked exhaust

or something worse- mechanical

Cracked jet pump housing or cone spun 

head gasket /crack head or other

I would think if I had a head gasket bad it would be running hot quickly,and maybe missing steam coming out exhaust so I doubt that

 I have not taken out the plugs but it is possible that compression is going into the exhaust but I don't think so

I'm debating getting a newer ski anyway, although will still have to fix this one, and I don't really use it allot either

My friend has a 2006 Kawasaki 200 LX but I like Yamaha s better

I can take off the pressure regulator on side of block

 make sure that there is good water flow coming to all of the parts maybe take off the muffler first

see if it's blocked

I did "search the forums" some for some answers and did learn a few things but still have not found the problem.(yet)

We took out the ski the other day about 5 minutes from the ramp the high temperature alarm came on and the beeper

went into limp mode. Let it cool and tried a few more times same thing, then idled back to the boat ramp.

The ski did this one other time last year and then "it went away".

Thanks John for the suggestion to back flush it good idea. I pushed water back into the block side of thermostat hose other night.

I did take the thermostat off when we got home and it tested ok, cleaned the housing and put it back on after 15 minutes running on the hose it ran hot again. I then got my infrared thermometer out and checked the head temp while running on hose slowly came up from 140 to 175 about where the alarm would come on so I shut it down.

There may be some restriction in the cooling system somewhere. I did take off hoses and pushed water through them seemed clear

From what I read on the forums running hot some possible causes are:

Blocked pump jet pump engine inlet strainer or supply hose          *(maybe not on water hose)

blocked hoses

bad temperature sensors

blocked water passages

blocked exhaust

sand around cylinders

impeller clearance        **(not on water hose)
