I have read and heard that too, what I am saying is I have tore up so many merc lower gear sets though that IF I ever were to spend another large bundle of money on a SCX I couldn't see running a sc lower which I know will chew the gears up in 15-50 hours on a big power boat, it is definately a dillema, Smitty

My mistake. What is the size of your additional larger oil cooler? Did you retain all the stock 496HO oil plumbing lines and fittings along with the stock oil cooler and just splice in the extra oil cooler?

I can buy a lot of oil for the price of any drive much less an Arnesen. The Arnesen sounds like the perfect drive for your type of hard charging boating. I mostly just cruse around with a load of folks or wake board.

Is the "AMS Oil AGM" Amsoil Severe Duty 75W90 or exactly what?

I used original plumbing for the oil filter assembly. Left stock oil cooler in its place and put in another 2 1/4 inch cooler and made the lines to fit using push lock.

The AMS Oil that I have used in the drives is AGM-QT Marine 75-80/90 weight.

I guess I have been lucky thus far. God, did I say that?

I've not had any lower gear issues even in my abusive moments..

SD,
I completely agree with your thinking (that the Arneson conversion is the way to go compared to the bravo alternatives), but when you're looking at well over $50k to convert over twins, I would suggest you might be better off selling the boat and buying something with better drives already on it...

And I thought about that but many things to consider.

The boat I own is the evil I know. If I buy another boat, I go from a single to twins and if it has surface drives on it great. But what kind of shape is the rest of it in? Engines? Trans?

Over all, it's not a clear easy choice to get another boat. I built this engine. Started from scratch with fuel delivery and many other things. I know the condition of everything. I've slowly fixed and upgraded everything the way I want it.

Starting over would be worse than swallowing a gun.

Steering kit - 3500
used good drive - 3000
my props - 900

sweet talk arneson down from 23 to 19

19 - 7400 = 11,600 plus some fiberglass to get the ASD-6 hung.

If I had a twin engine boat. I would have stopped at about post number 10...

Still seems like a toughy to me even if I don't get the 6 for 19. Say you pay 20 or 21? Still close. And when you consider that I paid Tom 6495 for the XR to begin with????

And that is what I have been leaning towards. SCXs. HMMMM

This last oil change a few days ago came with some funky oil in the bottle. It looked as if the oil in the bottom of the bottle had a "jello" type texture to it.

Drained the bottle and rinsed along with flushing the line out.

It has barely 100 hours of run time. During which, I've changed the oil 4 times.

That "jello" stuff might be what the AMG oil looks like if water gets in it. Just a thought.

What power, gear ratio and prop are you running with that Bravo?

I feel your pain ... had to replace both XR gear sets last spring. I change the oil every 10 hours . Amsoil 75-110 works best for me.
It looks like your gears are trashed after just 100 hrs ... :eek:

When mine broke it had less than 20 hours on it . I took the lower apart and checked for parts and everything was good. Cleaned it and put it back together. Running Imco lowers so I guess I got lucky as well. It broke 1 tooth and rolled it threw the gear set which pushed the cap off and broke the housing . 1 phone call to Gavin marine & $3200 (at the time, now 4200) later I was good to go. Best of luck Jeff

I also originally thought that it was driver error or
set up issues also( before I had a boat with XR's) but it's
not.

Seems like it's a 50-50 chance on getting a good set.

I equate it to laying down sod over dirt that is
littered with junk.

It looks good initially, but pretty soon the uglyness
starts showing up:eek:

I've had them pit out ( like the pictures), crack and shear the cone off the gear, and the fun one, break a tooth off and junk out the case.:eek:

If and when the next set crap out, I'll probably switch
to X gears

What power, gear ratio amd prop are you running with the Bravo? Average hours to failure?
