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

4 and 1/2 quarts without a spacer. Chris

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.

They are the exact same thing as a TRS ,,only diffrents is the shape of the lower and the length.
I say 600-700 and ok on the throttles not a problem.

thanks chris!!!
