Yamaha 150 4st running temps

[MattyDucati]

As the title states, if youve got a yam 150 4st where does your temp sit?
Also where does your oil pressure sit?

My water temp sits around half when under 4000rpm and then around 3/4 above that and at wot its on the top marker on the gauge:o
My engine is a 08 mod with 200hours.
Is this normal?

I have a couple of Yamaha Ft60 4 stk they both sit between 60-61 C at cruise RPM of 4800 hope this helps .

does it give the temperture in degrees

[fromeo]

No actual degrees on the std yamaha guage , I have a HDS5 networked to the motors which sends engine temperature

If there is an issue the Kelly alarms will sound. I did an impellor one day with mine and it would let me limp though the alarm is ear piercing. It got up to the top of the guage that time though normal running it was always half.

hi
I've got a f150 yammie2008 with 300hrs and my temp gauge sits at half when just idling or trolling and goes one bar past the middle when cruising at 4000rpm or over hope this helps will be going in for a service soon and will get a new impellor with is due for the 300hr service

[MattyDucati]

thanks guys, yeah just a bar on my gauges, i will be doing the water pump soon.
Is there anyway to test the alarm as i have never heard it?

[johncar]

Those indications seem normal.

Mine also sits on the halfway mark most of the time at cruise speeds.
I never use WOT except for propping measurements which was only brief and never looked at the guage.

I will take more notice next time out which hopefully wont be far away
