The kit usually comes with a little packet of lube. If it didn't, I just coat it with lightly with vaseline.

Liquid dishsoap and water wipped into a frenzy by a high speed impellor. For one, I would think there would be a sudsing effect. For two, I would think it would quickly dissipate. I've heard of dish soap. I would prefer to use Quicksilver 24c. I would think even white lithium grease would be ok.

I don't think it matters really. Whatever you use will go away in short order. Its only purpose is to ease installation and to possibly prevent wiping the impellor upon initial start up. But even the latter is questionable because everyone knows not to start the engine unless the boat is in the water or connected to muffs so the impellor wouldn't be dry.

Yesterday afternoon I pulled anchor and left the cove we stay the weekends at to go to the south end of the lake to meet family. About a half mile out while running at 1800 rpm the engine alarm went off. I shut the engines down and dropped anchor. I turned the keys on and noticed the port engine was at 200 f. I went to the swim platform, the Admiral started the port engine and no water from the exhaust. The starboard was fine. I weaved my way back into the cove on one engine and dropped anchor for the night.
One drunk on a 32' Sea Ray asked what happened, I explained and he stupidly replied - "yea, I always here'd (yes he said here-d) Maxum ain't to reliable". I relied, "Maxum does't make engines. Its a Mercruiser, the same make you have."
This morning I pulled the pump off and sure enough the port impeller had sheared all 8 blades. I slid in a new one and went ahead and changed the starboard while I had everything out. One and a half hours start to cleaned up. One thing I do love about the 3700 is there is plenty of room to get to everything.
The attached picture shows the port and starboard impellers.

Every weekend during the summer I am endlessly amazed at the things people do.
