Mercury 25hp 2 stroke pee stream is pretty darn hot!

2001 Mercury 25hp 2 stroke

Is this normal?  I can hold my hand in the stream, but it is at the upper level of toleration.

I changed the water pump once and it was peeing, but with a little hesistation.  I pulled the lower unit and notice one of the 6 vanes was bent backward. 

I installed a new impeller and turned the drive shaft "clockwise" to seat the impeller in the housing.  I installed a new thermostat.

It is still peeing very hot water and seems to be peeing at 80% capacity when compared to my spare 25 merc's pee stream.

Questions:
Is it normal for Merc 25's to pee very hot water?

Is turning the drive shaft clockwise correct?

Is there something that I'm missing or should be looking for, other than the water pump and the thermostat?

** Here's another one for the book.

When I first bought the boat and changed the water pump.  I was running some extremely low water and the pee stopped.  I went about 250 - 300 yards and shut the motor down.  I jumped out of the boat to inspect the water intake covers on both sides of the foot for debris.  The bottom was muddy/sandy, so no grass was present.  I thought I picked up a plastic bag or something.

There was no debris on the plastic intake plates, so I took the plates off to see if something had lodged inside the grates...  Nothing

Then I inspected the plastic plates and noticed the tiny inlet holes were basically melted shut.  I had only run the motor 1/4 mile looking at the pee stream the entire time because the water was so shallow and when the pee stream stopped, I shut down within 250 yards ( I had to find a place to drop into).

Has anyone on this forum ever heard of this occuring?

I've asked my mechanic and he said he's never heard of this before.

I was praying I didn't fry the motor, but chaged out the inlet plates, installed a new impeller and themostat and checked out the compression to make sure no damage was done.  Compression was/is 120/120psi on both cylinders. 

I have put about 10 hours on the motor since than with no issues, other than it seems to be peeing hotter than... say my Yamaha 40hp pee stream.

I know that these Mercs use high volume / low pressure cooling, but really have nothing to judge.

Any ideas?

 

Brett,

I mean the tiny holes in the plastic plates were melted shut.  It was peeing normally on minute and the next no pee at all, just steam.

The holes melted shut within a 1/4 or 1/3rd of a mile run.

I think I've thrown the old plates out, but I'll take a picture if I still have them...

The thermostat Mercury Part# 14586 is supposed to be a 120 degree thermostat, so I run the motor and check the temp. It seems hotter than 120 to 140 degrees.

 

Instant coffee water temp is right on the money. I already changed the thermostat with no issues and used a light coating of marine grease before reinstalling the bolts.

Broken bolts are a beech!
