And now "The rest of the story" as Paul Harvey would say... I just replaced the empeller myself and must have done an acceptable job b/c the pee stream was strong and the water temp and head temps were good at 130* and 140* respectively.
The newer lower unit (SEI) seems to be doing ok with 266 hours / 4 years of use. The gear oil is always in good condition and no water in it when I change it out each year.
Now the bad news... I am on the Green Peace official "Watch list" and have the Bob Barker trailing me ready to ram!! This is because of my fluids loss...from all cavities. Specifically, my trim/tilt seals are going bad and leak hydraulic fluid. I just fill the reservoir every year lately and go on with my business. Also, my oil injection pump has leaky seals and at rest it drips slightly down the mid section on the motor. It makes a beautiful rainbow shene when it hits the water. Makes the crew of the Bob Barker mad, but the motor still runs good enough to outrun them (35 knots vs. their 15 knots!!)
And my 3ea 2V carbs need to be resynchronized b/c they are just a little out. But all in all the motor runs great. Especially at idle and planing speed. I think I'll keep it another year or twelve...LOL!!
