8) OS Max 9B carburetor mounted to the Nelson .45 long stroke engine. The carburetor has a machined delrin velocity stack. Both needles have been set.

9) The K & B lower unit has a hardened brass stuffing tube in place of the stock teflon piece. The stuffing tube & the K & B unit's pivot shaft have grease fittings.

10) The entire K & B mounting bracket has been redesigned to give maximum adjustment & remove any looseness usually found on stock units.

That is some of the nicest installations I've ever seen on a tunnel boat.

Colonel Beasley, Bob & Jerry,

I'm working on the boat & engine as I write this Colonel Beasley. I have added custom built ceramic hybrid bearings with polished races for this year. Bob, according to our Stalker radar gun the coating makes the boat approximately 2 to 3 MPH faster. One characteristic of the coating, if it is properly mixed & applied, is it's resistance to surface scratching. I used the same type of coating on the gas rigger & found the same results. The coating is not sanded to a very smooth finish. Accurate determination of the speed increase is difficult because of changing water conditions. A large speed increase & precise control of the engine from low to WOT throttle was accomplished with the OS MAX 9 B carburetor mounted on the Nelson .45 long stroke engine. This is the same engine as the FAI speed engine, but with a left hand crankshaft. The crankshaft has a .750" OD & a flow ramp is used inside. Thanks Jerry. I have a Lee Craft XT-460, courtesy of Lohring Miller, that I may attempt to setup if time permits.
