Teague On Tech: Q & A with Bob Teague September/October 2021

As seen in Speedboat Magazine’s
September/October 2021 Issue.

Low Oil Pressure

Dear Bob:

I have a 2000 Mercury carbureted HP500 with an M3 ProCharger in my boat. Last winter, after 470 hours of operation, I had the engine rebuilt. I had asked the builder to install a high flow oil pump; however, I believe he installed a standard Melling M77 oil pump. Prior to the rebuild, my engine had oil pressure of 70 to 75 PSI at WOT (5,000 rpm). Now, the highest oil pressure is 45 psi.

Teague On Tech: Q & A with Bob Teague August 2021

700 SCi Head Gasket

Dear Bob:

I have a Mercury Racing 700 SCI kit. I ran the tank out of gas while under power. I did a compression test that showed 60 PSI on cylinders 4 and 6. The rest of the cylinders tested between 120 and 130 psi.

I took the motor apart and it looks like I just blew a head gasket. Is this a common occurrence? Should I just go back with a stock factory head gasket or is there something better? Is this commonly caused by running the engine out of gas while at full power?

Any information you can provide would be appreciated.
