I was helping a freind of mine today getting his 26 Offshore up and running, it hasn't been run in over two years, has a pair of 1997 150 Mercs. everything else taken care of over the past two months,Has been running fine on the trailer, took off from the landing, went about two miles, and the port engine started sounding an alarm. Checked everything out, found the oil pump not pumping, the crank gear was stripped. I tried to talk him out of repairing the oil system and just premixing, but he wants the oil injection operating, so I'm pulling the powerhead next week to replace the oil gear. I allready warned him that the starboard engine will probably let go also, I guess I will do that one when it happens

i'm still running the oil injection on my 94 merc(1400 hrs), but i carry a extra gallon of oil and at the first hint of a horn or hiccup i dump it in the gas tank. the bad thing is usually the first indication you have is a seized engine. i was talking to a engine re-builder at the miami boat show about 10 years ago and he said the 2 best things for his business is oil injection & thermostats.

your engine, by being run on a regular basis, is probably less likely to fail than my freinds 150s, both of these engines have set for a while without being used. I once worked on the water taxi's 150 yamahas, I replaced the original impellers in them at 2000( 2 years old) hours, they get run every day, and except for some wear on the tips, they were still flexiable
