Where do I install a temp gauge sensor on a 2006 60 hp merc 4 stroke big foot . Thanks John

a lot of the temp sensors you add on can not be wired to the temp alarm sensor. you will need a little bracket that bolts onto the head and holds the sensor next to the head. I would put to in the middle of the head to get the best reading.

1985 150 hp black max ,lost spark , i replaced stator and it still checks out good ,the trigger is not checking out good ,would this cause it to lose all spark ,or would it be the switch boxs ?

If the trigger is not working it will not fire.. the trigger is kinda like a set of points in an older engine...tells the ignition when to fire..

90 HP 4 stroke runs smoth as silk at 1800 move higher and it stalls have replaced several parts rebuilt carbs no help

when an engine stalls or looses power at high rpms , it is because there is a higher need for fuel to supply that requirement
fuel shortage can be from
blocked filters
low float levels in the carby/s
vent problem in the fuel tank/s
perished hoses letting in small quantities of air
the hoses failing intrenally and blocking off the fuel flow
pump problems from bad diaphragm or the rubber in the hose again blocking the main jets in the carby/s
another area to be checked is the ignition system being able to provide the spark at a higher rpms
this problem can be from failing condenser, ignition module or coil/s

Water in engine oil.

water can get into the engine oil from several points
if the engine has a sump oil cooler hen the cooler coil wil be cracked or corroded at the seal points
more likely the housing behind the water pump has corrosion in it behind the impeller and water pressure is making it leak into the sump
