Can I run without poppet valve?

[shelbydriver]

I suspect something is making this motor run hot. Poppet valve is suspect. Can I just take it out? Is it going to leak out the weep hole? Runs hot at cruise. Water pressure is 13 at 5500rpms 2 at idle. 94 200 mercury xxl

The poppet valve is there to protect the engine from cold water hitting the hot cyl's.<br /><br />It is a NO NO to remove it.<br /><br />Have you done some work with the water pump recently?<br /><br />Did you silicone the divider behind the waterpump that separates the exhaust from the water pump?<br /><br />TMD

yep siliconed the area to keep the hot exhaust gasses from passing. Did the pump housings too.

Is this the same engine that you have been working on for a while now?<br /><br />>RFish>
