? For BRM
How often should you change the plastic gear that drives the oil pump on a 150 EFI Merc? Trying to establish a service schedule for this boat and motor. Thanks. Now get back to work.

I was doing a search and ran across this info! Hope it helps!
Oh gosh, another poor consumer stuck like I was at one time. Here is what I learned about the problem well known by Mercury but neglected to inform others.
There are nylon bushings around the worm gear (metal) and the plastic drive gear in the block. When these motors sit for long periods of time the nylon bushings will swell and cause stress on the plastic gear. Thus, the gear strips out. Unfortunately you do not know this until the rotation sensor on the oil pump alarms that oil is not pumping when you are running. Motor is toast then.
I went through two 1998 Mercury EFI's within 2 months. After much research and many phone calls to Mercury I eventually ran across a gentleman who is manufacturing electronic bolt-on oil pumps. He was retired from Mercury, a former director in customer service and informed me that Mercury had a rash of these every year after the motors had sat for long periods of time without running. He said those who ran their motors once a month generally did not have issues, but the typical owner who let it set all fall and winter would be susceptible to failures.
In about 2000 they started using brass bushings, these do not swell and are supposedly a fix for the problem. All new powerheads have them which is what I learned from my dealer who replaced the first motor after I had brought the boat in for the 2nd failure.
I didn't buy the electronic pumps though I was very inclined to do so vs. running the original setup. Plastic inside the block just doesn't feel right. I sold the boat soon after the 2nd motor was replaced with the factory setup on the pumps. I am out of the Mercury business for good.
The $2200 for the reman powerhead is standard pricing from Merc. This is what the bill was for mine to be replaced, but I did have 5 year warranties on my engines which went out in last couple of years. Word to the wise, Mercury doesn't like to cover the 2nd motor in the last year when you have total failures.
I haven't talked to many people about the electronic pumps, but it sounds reasonable. Supposed to have a MTBF of around 600-800 hours which is much longer than the motors lasted with the old pump anyway.
