Oil Pump?

[xdgt03]

I have a 1990 OMC 4.3l chevy motor.

I had an oil leak at the front of the motor where the timing chain cover and oil pan meet. I took off the timing chain cover and discovered that the timing chain had about 5/8" slack in it. I changed the timing chain and gears. I removed the oil pan and oil pump. I am going to replace the oil pump while I'm at it. They make a high volume oil pump. Is it a good idea to replace it with the high volume? Does it come originally with the high volume for a marine application?

Thanks for any info

Howdy,

I really think you can get away with a stock pump. Most pumps will provide plenty of volume in marine engines since the engines do not turn more than about 5000 rpm. If a new stock pump couldn't provide enough pressure, you probably have worn main, rod, and cam bearings.

Nope,... Use the Standard pump....
