    Question Ilmor and the boys

    I am trying to justify a pair of Ilmor motors and some arneson surface drives. The price seems so steep. I have built motors for boats in the past and I have had good luck with them. The caveat is that I built them very close to stock. It was a simple process of switching to stainless hardware. I am now building a go fast boat (37 Coyote) and I will need more ponies to get the boat to a speed I can live with.

    The Ilmors will pull true HP/torque as advertised. There are other builders out there I know this won't be a cheap proposition. I would like to be confident about the both the power plants and the price I paid for them. Also, Ilmor has its Indy drive and ICE control system. I've been in boats for a while and I have learned that the price is more often than not a loose ballpark after you get all the goodies needed to actually implement your newest marine widget.

    Any tips?

    I'd buy another Ilmor in a second, I have a 710 - it and the 725 are rocking bastards.

    I love the merc 700 as well, its a great mill.

    For something really stout - I'd go to boostpower,
    - or get an Ilmor that boostpower has reworked.

    They are the only entity outside of Ilmor I'd trust inside my 710.

    Thanks Uncle Dave,
    I will look into the boostpower options. That is a great testimonial. What are the drive packages you have used that you might recommend?

    Drive packages that I have used that I can recommend.....thats a tough one.

    If I had the ilmor in a tunnel Id probably run an Indy, but I dont I have a stepped v which doesnt really like cleavers.

    Im running a modded Bravo1 XR called a teague platinum drive and a Mercury ITS steering system (awesome part)
    This about like an Imco SC, but a marked step down from an SCX, or NXT/Indy

    I had a drive failure at 8 hours covered under warranty by teague and had to do a rebuild at around 50 more hours.
    This is largely due in my experience to a high percent of ocean running.
    On lake you will likely get around 100 hours or more between builds as you dont stress the gears in both directions nearly as much.

    Go with the Arneson and never look back. They are damn near BOMB proof, and will go HUNDREDS of hours between rebuilds. I will never build a high performance Bravo boat.
