Thanks cougarman, made the rest of the parts for the exhaust cooling systems and had a final mockup of the exhaust tailpipe pattern this has now been collected by Carbon weezel who are going to manufacture two carbon tails from it. The stainless steel tail would weigh 7 kilos, carbon fibre is going to be around 1.5 kilos

The time, the detail, your own hands getting it done.
Sweat equity!
Thanks again for sharing

Hi All,
The stainless part of the exhaust has now been fully welded and is ready for ceramic coating. I mocked up all the raw water cooling pipes in a mixture of silicon pre-formed hose and carbon fibre tube, these are large bore to allow a geater volume of water through the heat exchangers and the charge coolers.Vein type water pumps become very in efficient with back pressure.Also made a carbon fibre bracket for holding the battery master switches.

Hi Chuck,
The battery isolators are made by a british company called albright international, they are magnetic latching and spark free, i also use their polarity change over switches for driving the trim pumps saves a lot of wiring.

Hi Jon,
Parker build us special hydraulic pumps with a permanent magnet motor that only has two wires it has almost twice as much power as a mercury racing trim pump enabling us to move the drives much more rapidly. The albright polarity change over switches are wired directly to the battery isolators and then you only need two trigger wires one for up and one for down, by mounting the two trim pumps on a carbon sheet including the switch gear they are just over half the weight of a pair of merc racing pumps.
Pictures are of the Ilmor engined boat that we are currently building.

Hi all,
Made loads of progress... Bonded a piece of carbon fibre into the lightweight dashboard which i have now cut to fit a pair of garmin screens so it will be very similar to Carbon Cheetah, also installed trim pumps, electric and mechanical bilge pumps and some of the steering hoses should get the engines back in next weekend.
