Sorry for the double post but I need to get my gear lube ordered today.

Does anyone know the gear oil capacity, or who/where I can call to get the capacity, for Speedmaster II drives?

Thanks

How is the Speedmaster II run? Hold up? How much HP can they take?

Just depends on how your drive it. One of my buddy's has a 40' Monza that ways ruffly 14k lbs and he is running 2 blown 496's putting out aroud 750hp and has never had a problem with his.

I am running them on a 1985 Chris Craft Chris Cat. Other than one of the upper cases having a crack in it (that way when I purchased the boat) I haven't had any problems on my stock 502's.

But neither one of us punish our beat on our boats. I have never seen his boat come out of the water and I have never had mine come out of the water, yet...

It's all in how you drive them, with 600+ hp if you don't treat them nice they will grinade really easy from what I have read.
