Water flow is low, 85 hp

[beach]

1984
85 hp
4 cyl.

Is there a t-stat? Haven't been able to find one.
Only a dribble of water out of the tell hole and the psi guage reads 0-1 at idle and 4 psi WOT. Haven't run it much till I figure out if it's getting proper cooling. New impeller installed. Any places to check for blockage or flush out any restrictions.

Definitely have some issues there. Do you have a manual? Check the poppet valve, and yes you should have a t-stat.

1984 85HP 4-cyl doesn't have a 'stat or poppet.

You need to install a new water pump before she burns up!

Good deals at www.boatfix.com for Sierra Marine aftermarket replacement parts for your Merc.

Run awire through the tell tale hole. disconnect the tell tale hos at the block and see if you can blow air through it.

Yes I do have and manual and replaced the impeller.

Ran it a little today at the marina. Not much water comming out of the tell hole still but at the back of the motor where the exhaust is coming out there is a steady spray of water.

I will check for blockages at the tell hole connection to the motor. There is a "T" there for the pressure guage i will have to remove.

Any more thoughts or places to look for blockage?
