Checking Gearcase Condition-New Impeller

[IBrokeMyFreakinNeck]

How long of a job is taking the gearcase off of my '72 merc 115 inline 6 and checking the impeller and regreasing, etc.? Just wondering, my mercury manual hasn't arrived yet. Are the impellers readily available for this year motor?<br /><br />Also, I just bought some Seafoam after reading several posts about how it can get all that old carbon off the pistons and free up the rings. I just brought my motor back to life and have run it just once on the muffs. Seems to run strong and idle good. <br /><br />I also have been busy on the trailer, sanding, priming, painting, and re-wiring w/new light kit.<br />By the way, since my whole rig is a '72, I thought it would be a good idea to change the wheel bearings on my trailer. Man what a job! It took my brother and I about 3 hours to do just one side(though I had to get the bearings out first before buying new ones). Still have the other side to do <br /><br />Billy

Seafoam = snake oil in my opinion. Mercury's Power Tune actually works. Just follow the instructions on the can.<br /><br />An experienced mechanic can do that water pump in 1/2 to 3/4 hour. First timers will struggle with getting the unit back on. 47-89984 impellers are still readily available and were used for decades in everything from 650s to 140s. In MerCruisers, too.
