After 16 months on a new Power Head my 50 Merc started to seize at top
end. Compression test showed #1 & 3 at 128 and #2 at 26 pounds.
Separated the crack case and found the oil pump gear was stripped.
Mercury shop said they had never seen a 50 with that problem. I
couldn't believe that a Plastic GEAR was used to supply oil to the
engine!

I'm not happy trusting a plastic gear on the crank case to supply oil
to the engine. I'm looking for advice on removing the oil injection
system and premixing.
1. Is this adviseable
2. Do I remove the oil pump and block with a plate
3. How do I remove the oil buzzer and not affect the over heat alarm
4. I don't idle much. Will this have a negative affect on the engine

At least that way I'll know for sure that the engine is being
lubricated.

2003 Mercury 50 HP
Serial Number OT840672
3 Cylinder / 2 Stroke Engne

Any input appreciated.
