There seems to be no shortage of rarities in the 450-car John Scotti Collection that's currently rolling across the block in Auburn, Ind., at the Auctions America sale. While the lion's share of the collection consists of American muscle, there are definitely a few cars in the sale that will make classic-car aficionados do a double take. One of those is the NSU Ro80.

Honda hinted at the second coming of the NSX sports car in 2011, before bringing a concept to the Detroit auto show in January of 2012. Not more than two months later, the company said it will also go racing with the hybrid all-wheel-drive supercar. This has finally come to pass: On Monday, Honda uploaded a video to its Japanese YouTube channel, showing the Honda NSX Concept-GT -- the racing version -- in action at the Suzuka Circuit. more

The Jaguar C-X75, pictured at Goodwood ahead of its Supercar run Jaguar are pulling out all the stops for this year’s Goodwood Festival of Speed with not only their latest performance cars but the debut of the Jaguar Project 7, an F-Type R with the DNA of a D-Type. But they’ve topped all that by deciding that their canned supercar project – the Jaguar C-X75 – deserves a proper outing in public. Jaguar only have five development versions of the C-X75, but they’ve taken one to Goodwood – although it’s not on display – and are wheeling it out over the weekend to take part in the Michelin Supecar run up the hill. more

In the photo below is the 5" water tube extension needed for the long-shaft conversion. Also used is a O-Ring seal # 202893 which slid inside the tube extension and was secured inside the expanded ring. Also in the photo below is the grommet, just to identify the direction the tube is placed, as this tube will insert into the grommet in the water pump outlet. here

The inner exhaust tube is the same for either the short or long shaft motors. There are no gaskets or seals needed for these conversions. [links]

I have shortened long driveshafts and welded them back together. Short shaft overall length is 22 9/32". If in doing this you would finally have to be sure that it is straightened so there would be no wobble. Again if doing this, go to a welding shop that can weld stainless with a wire feed welder (more penetration), grind the mating ends to a cone type taper with the center about 3/16" dia left. Place them in an angle iron that is mounted in a vise so it forms a Vee to hold it in line for the initial weld. Once welded and initially straightened, the weld can be rough turned down to slightly oversize to the outside diameter and at this time while in the lathe, ran, straightened, ran again until it is close with the least amount of wobble.

Or another method would be to make a sleeve, 2 to 3" long that can be slid over the shaft, have it welded to the shaft on each end of this sleeve. This would change your installation procedure slightly as the water pump unit then would have to be slid onto the shaft from below before you installed it into the lower unit. The splice would need to be maybe mid point between the water pump and the upper end, or at least enough above the water pump so the pump body could be installed above it's final location, then slid down to mount up.

Actual Removal of Gearcase or Lower Unit to Access the Driveshaft &Water Pump : � If the motor has been used in saltwater to any degree, I will guarantee that at least a few of the bolts will be seized in and will be twisted off. I will cover this in a separate section. Have the motor mounted either on the transom of the boat, or on a motor stand or saw horses. � It also will make a slight difference in the procedure whether the motor is a long shaft or not. There are 6 stainless, 1/4� bolts with 3/8� heads that come in from the bottom and are bolted up into the exhaust housing assembly. � If it is a short shaft, they are the only ones there. � If however it happens to be a longshaft, there is a 5� extension, or if a Sailmaster a 10" extension between the lower unit and this housing. � If so, then remove the upper 6 bolts. � The lower 6 bolts attach this extension to the lower unit.

The driveshaft may have a O-Ring around it on the splines that engage the motor crankshaft. � The earlier motors had a groove around the shaft for this O-Ring, while the newer ones had the O-Ring in a internal groove in the lower end of the crankshaft. � If it on the shaft, remove it until you are ready to re-install the parts. more
