From my own personal testing of automobiles on chassis dynos, it's more like 4-5% per 1000'. But just my own observations.
Nice! We've decided not to be a vendor at the Havasu Boat Show this year, but I'm thinking about walking it one day...probably Saturday. I will also be at Desert Storm (on vacation).
Depends on the systems you have, but most likely you will have to have bungs welded in. CMI's for instance, have tailpipes that can be removed separately from the risers or manifolds/headers, and CMI will cut through the water jacket, drill the hole and weld the bung on the inside, then recover the water jacket to the outside of the bung for $150. Lightning headers offers this for their headers too, but only when first purchasing them. What do you have on your engines?

Rick, I doubt that Gordy from Phaff will travel from L.A. to Tahoe and tune your boat for 2 grand. Call Brad, he's been tuning on the lake for years. No travel time so you already saved a bunch. High performance translates into expensive boating. The correct tune is way cheaper than a blown motor. When I boat at Tahoe I try to clean up the idle so I don't embarrass myself more than usual around the docks. I always seem to have a black transom to wipe down,running a bit rich is cheaper than lean. Doug

Rick, I could join you but why don't you consider dynoing the motor. Great way to check for oil leaks before it's buried in a bilge and the motor is broke in and tuned at the same time. Keep in touch. We have a group that starts every year at the Lake Havasua Desert Storm run. Doug
