The oil I used was penzoil marine outdrive oil. I guess it looked good enough at the time. Now what do you all think?

youre kidding right?

Used Redline Heavy Shockproof in my Bravo One and it did not shift worth a crap, then it blew a top gear. I would stick with the merc stuff to be safe.

I use Redline Shockproof Heavy in mine. I think that's one of the reasons my drives have lasted so well.

redline is another 0 friction lube that I wouldnt recomend have had customers ask me to put it in and told them exactly what ive said here, I'm not saying your drive will blow if you use it im just saying the drive cone clutch works off of friction if you use a 0 friction lube it will have adverse affects on the cone

The only problem I have with Mercury HP is that you always get "metal on the magnet". A shop who runs Amsoil Marine Synthetic or Mobil-1 or Redline or Royal Purple or Torco... says next to no metal on the magnet. Racers use synthetics...

..oh and get showers.

merc hp is synthetic, and you are 100% right no metal no wear no friction, amsoil is not 0 friction......

unfortunately the bravo uses friction to shift so you just need to change your drive oil more often

Mercury told me their HP is semi-synthetic with antimony as a key additive for wear reduction.

You are correct

Now is it correct in that a Torco product is used by Merc in #6's?
