    Velet drive to TH400 questions

    My 21' Howard had a mild 468 and a velvet drive in it and I'm getting finished up on a 496 for it right now. I figure with close to 600 HP I should ditch the velvet drive before I blow it up. I got a TH400 for it and my buddy at the Jerrys Trans said a lot of guys just run welded up torque...

    so.... this may sound kind of dumb, but.... I've taken my boat out a couple times now and everything is running great. This last weekend I took it out to Long Beach and was running around a bit and I noticed a rediculious amount of steam coming from the exhaust. Of course at first was was...

    well I'm gonna start off with a new prop and if my rpms are still to high and I think the motor can pull it I will flop the gears in the drive. I guess if she's a pig out of the hole it will give me motivation to put the trans in it. What do you guys think is the most RPM I should run my motor...

    Ok, so it's official I am a complete dumb ass. Instad of using the split collar as a marking I actually marked the drive shaft and the prop shaft. It is just shy of 1 to 1. Meaning it is under driven by approx 10 to 15 percent. It is a Casale c500 v drive. Can the gears be flip flopped to make...

    Well. Carl as much as I feel like a dumb ass I have to admit that you are absolutely correct. I counted right but I said it opposite. I have a 2 to 1 v drive ratio. So I am 50 percent over driven no under driven. That's probably too much concidering my hp and only having the velvet drive trans?

    At 6k the boat was barley doing 60mph. I estimate the up at 500. What do u recommend me doing first? V drive gears or prop ? Is probably not a good idea to do too many changes at the same time correct? I tried to call Casale and pick their brain about gearing recommendations but I got not answer...

    Sorry for my ignorance with the gear ratio stuff on the v drive. So since I am at a 2 to 1 right now i am 50% under driven correct? and you are saying to go to an over driven set up that seems like a huge change to me wouldn't it be.

    Yeah I've been researching different steering and pedal set ups. Gotta figure out what is in the budget for this go around. I know how these projects can drain the bank account real quick. May have to wait until next years off season for some of the stuff but we'll see. I had seen in another...
