I have an '03 4.3L Merc engine. The dealer insisist that I should only
use Merc's motor oil, gear lube, etc. Of course the dealer price for
this stuff is pretty high. The gear lube itself is $15/qt. I noticed
that Walmart sells QuickSilver brand products now. I believe
QuickSilver is a respected brand in that I've seen it at WestMarine
and I've heard they are actually owned by Merc. So my question is...

1) Can I save money by buying Qucksilver lubes vs. the Merc lubes? Is
there really a difference?

Generally, no difference. As long as the lube in question meets or
exceeds manufacturer's recommendations. With my outboard, I buy
whatever oil is on sale at Bass Pro Shops or WalMart. The same with
lower unit gear oil.

2) I see a wide variety of prices for gear lube. It seems like there
must be two types out there but I don't see anything on the bottles to
indicate what the difference is. I've seen gear lubs for less than $5
and more than $10 per quart. Some say "High Performance" on it but I
don't know what the means. Are some synthetics and some not? Does my
outdrive require a synthetic?

There are price differences but the big difference will be between
synthetic and non-synthetic. Not for sure, but I'd bet your outdrive
doesn't require synthetic, but it might, best to consult your manual.

3) Is it necessary to put expensive Marine wax on my gell coat? My
boat sits outside and the cover doesn't protect the gell coat. I was
going to use the same turtle wax I use on my car but the Bayliner
dealer says I should use a marine wax. Is there really a difference?

I have opinions about wax and the shine and durability quality, and so
does most other people. But any quality wax should serve you well.
