#5 Drive oil.....
 

I have read countless threads on Bravo drive oils.... since I have moved up to #5's What works best for them? I am leaning towards Amsoil??? I am told #5's hold gallons rather than quarts ..... What is the recommended interval for changing? and any other p/m that should be preformed?

Randy

Hello Randy ,,,i use the merc High performance oil and do not fill any thing in the res., its only an expansion tank on the #4+5's otherwise it will push it out the bleader on top .

Just fill from botom up, then close top screw and pump a little more.

Amsoil is good too, i quess.

But i always think if its built with that ,,,that you should use that.
U wouldn't stick a dewalt batt in a makita drill just because it fits and works,,,,,,would you ?????!!!!!:ernaehrung004:

AMSOIL. Use it in #3's and #5's without any issues. BOB.

5's with Amsoil.

Ok ,,,then what amsoil ? And what is the diffrents ???

If its better then the merc i change mine.

Well I did some more research ...interesting link though 5 years old... http://www.offshoreonly.com/forums/g...e-oil-one.html . I liked Royal Purple on my XZ .

Ran 1050 Hp on #3s large shafts for years. The only oil they would live on!!

Also I stated this before they would burn up bearings and gears under 50 hrs with the merc green stuff.. Thats the reason I became a dealer. After 100+ hrs the oil looked like the day it was installed and so did the bearings and gears.

HOT P, can i run this in my crashbox and bearingcarier aswell ????

And how much do u need for case ,shipped to 34207 FL ?

Thanks

100 + hours running hard is just asking for trouble with any oil.

:eek: ok Im just a dumb as*!!

Thats what I ran in My Daytona crash boxes and tail stocks.

About 160. for 12 quarts?? Would need a full address for the correct tax rate and ship amount..
But should that should be close. :D

How many quartz do #5's hold??

5 gal for both

I use the Amsoil AGM product code which is 5 gallons for two drives as Kidapache indicates. Also run it in my drive couplers.

Have them drysumped only 3.5 quarts per drive.
Pick up power and fell better about your 1 mile to a gal habit. Going green and pick up some free HP> :drink:

HP,,,how much do u think it will cost to drysump a #4 or 5 ???

Have u seen it done befor ,or is that just a mind thing u have there ???

Would be cool i quess,,and what HP gains do u think it will have +20 or so ?

Cool idea !!

Interesting .......this can be done? more info please...

I too would be curious oto hear of potential hp gains. I am though concerned about the negative of damaging a seal and as the drive cools while in the water it fills with seawater. I hear that can be real expensive since there is a limited amount of oil in the drive there is plenty of room for water.

It has been done. Randy @ Marine Drives has done 3s,4s,& 5s. Not much difference if you can complete a dry sump conversion on 6s. I can get some pricing and Hp gains.
The 6s gain about 75-85 hp cant see why the same doesn't hold up for the 5s.
I will talk to Randy later this weekend and post back some pricing. Just have to remember that dry sump quotes dont include repairs- gears,bearings,shafts cant tell until there disassembled if all parts make the cut. :drink:

Thats only a problem on the total dry sumps that run tanks in the boat and a pump on the engine.The second and third seal never see oil anyway. First seal faces in and the second and third seal face out.
Mercs drysumps still hold enough oil when idle to the top skeg. When you running it drops down to right above the nose cone. Not as fast as a total drysump but less tanks,hoses,pumps and water!!
I check mine after every hard day and so far no problems.

Few shots of my conversion. Notice the #6 pump and filter is located in the nose cone.

wet sump to dry with new skegs

Six drive gears hold up better w/just a spray of oil rather than submerged in oil we found.Gears submerged in oil had higher failure rates and the newer upper gear sets are nice.

I agree!!!

Ok, I've decided on Amsoil severe duty gear lube.. now which weight 75w-90 or 75w-110?? and why?

I heard 110 ,,,but i could not tell u why . ?!

Also heard LUCAS oil is not bad.:party-smiley-004:

I guess it's Amsoil 75w-110?? Where is the cheapest place to buy??

I need gallons (5) rather than quarts....
