yes we raced Ns2000,which is F1 tunnels with the 2ltr merc rather than the 2.5
been 14yrs since i was last involved in full scale racing
got some amazing memories from them yrs racing the burgess hulls who again is 1 of my friends now retired from building,but we still keep in contact
heres a pic from the past of our hull and yank tank van LOL @ lake windermere before they stopped racing on the lake
WOW. Those are great pics. Looks like that series runs cats, monos, and hydros. I found the rule book below and the rules for those boats follow our rules for the definition of outboard and inboard motors. See below:

F19 MOUNTINGS AND TRANSMISSIONS
Outboards
1. Mounting brackets and clamps must be secure and in a satisfactory
condition.
2. Engine mountings must be attached to the transom with at least two
clamps and two bolts, or four bolts secured by locking nuts.
3. All clamps must be adequately tightened & secured.
Inboards
1. Engine mountings must be sound, and the mounting bolts securing to the
hull must be pinned or lock-nutted.
2. Where an outdrive is fitted, the outdrive ring connection to the transom 26 | P a g e

and the unit to the ring must be secure
3. All moving parts likely to cause damage if broken must be suitably
shielded
For shafts in excess of one foot in length the shielding must not allow
more than 1/2in clearance at either end.
4. Bearers must not be saturated with oil
Wikipedia description:
An
outboard motor is a
propulsion system for
boats, consisting of a self-contained unit that includes engine,
gearbox and
propeller or
jet drive, designed to be affixed to the outside of the
transom and are the most common motorized method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The
skeg also acts as a
rudder when the engine is not running. Compared to
inboard motors, outboard motors can be easily removed for storage or repairs.
When boats are out of service or being drawn through shallow waters, outboard motors can be tilted up (tilt forward over the transom mounts) to elevate the propeller and lower unit out of the water to avoid accumulation of
seaweed, underwater hazards such as rocks, and to clear road hazards while trailering.
In
naval architecture, a
transom is the surface that forms the
stern of a vessel. Transoms may be flat or curved and they may be vertical, raked forward, also known as a retroussé or reverse transom, angling forward (toward the bow) from the waterline to the deck, or raked aft, often simply called "raked", angling in the other direction.
[1][2][3] The bottom tip of the transom can be approximately on the waterline, in which case the stern of the vessel is referred to as a "transom stern", or the hull can continue so that the centreline is well above the waterline before terminating in a transom, in which case it is referred to as a "counter stern"
[4] or "cutaway stern."
[5]
On smaller vessels where an outboard motor is the source of propulsion, the motor is usually mounted on the transom, and held in place either by clamps or metal bolts that go through the transom. In this arrangement, all the power of the motor is transmitted via the transom to the rest of the vessel's structure, making it a very important part of the vessel's construction.[6]
Can someone tell me why we need a rule addendum to clarify the obvious description and known rules for Outboard Engines and Inboard Engines?
