NZMPBA Rule changes and National Championships Class variations. Becomes effective 6th April 2015.

National Championships considerations.

1> Nationals remains at Easter and runs over 4 days, starting Thursday and finishing Easter Sunday.
2> Nationals are to be “class specific” ie no cross entry of any boat ( as it already ran ) into other classes except as allowed in Marathon and the appropriate Open Oval event.
3> P2 Hydro is not to be run as an event as such, this is facilitated by the following sub classes being run: T2 Thunderboat, Sport Petrol Hydro and Outrigger Hydro.
4> In the Nitro Mono, Tunnel and Hydro classes, A,B & C1 shall be merged. ( Ie upto 10cc class)

NZMPBA permanent rule book changes.

1st Proposal: That in T2 Thunderboat ANY brand of petrol motor upto max 27cc is allowed.

Wording of Rule book to be amended as follows: ( under Engine Specifications)
1> Any 2 stroke petrol engine can be used upto 27cc. Electronic or Magneto ignition is allowed.
2> Delete completely
3> Leave wording as is. ( re number as #2)
4> Delete completely

2nd Proposal: That Sport Petrol Hydro be limited to Pickle Fork Hulls.

Wording of rule book to be amended as follows:
5> Hull configuration shall be Pickle fork only, The Pickle fork shall not exceed 25% of the hull length ( Hardware and other appendages are excluded from O/A length)

3rd Proposal: That to allow for the adjustment of P1 Class ( to become “stock class”) then under General Rules 4. CLASSES, P2 is adjusted as follows:

P2 class. Up to 27cc Petrol and oil only. ( No other additives allowed)

4th Proposal: That P1 class becomes the “Stock Zenoah” class that includes Mono, Tunnel and T1 Thunderboat ( now to be known as P1 Thunderboat, this will eliminate anyone trying to cross enter the same boat into T2 Thunderboat as is now recognised as a completely differently named class.)

Under General Rules 4. CLASSES P1 is adjusted as follows:

P1 class. ( Mono, Tunnel and P1 Thunderboat only)

Engine Specifications.

1> Engine MUST BE a stock standard 231 or 260 PUM Zenoah only. No internal modifications are allowed either by removing or adding material to or from the engine, with the exception of relieving the side of the piston at ring area to prevent seizing. The cylinder and head assembly must be a single unit as standard ( no removable heads and / or head buttons allowed)
2> All stock gaskets and seals must be installed ( No splitting of paper gaskets or using thinner replacement gaskets is allowed )
3> Engine must run with stock Grey and Red coils.
4> Spark plug can be any standard type (unmodified ) and must have its washer installed.
5> NO “stroker” crankshafts allowed.
6> NO other after market parts allowed, eg aluminium carburettor isolator block ( or other even if only cosmetic in terms of colour etc)
7> Any factory issued standard carburettor may be used, WT - 603, WT - 644, but can be substituted with a stock WT-257 ( NO modifications.)
8> Any exhaust system with water cooled manifold is allowed. All boats must meet the current NZMPBA noise rules.
9> The engine must be equipped with a recoil starter used as the primary means of starting the engine, the standard Zenoah recoil can be substituted with an “Ezy Start” recoil. Belt starting is only allowed as a secondary means of starting the engine.

5th Proposal: To align the current T1 Thunderboat rules with the above, make the following adjustments to Stock T1 Thunderboat as follows:

1> Re name: STOCK THUNDERBOAT (P1)
9. Engine Specifications as per P1 class in General Rules.
(Remove ALL notes regarding Engine Specifications under T1 Class rules as these will now be noted in General Rules)

Thanks for your reply Pete! No reason for apologies it's all good! Just wanted to point it out so it can be correct and other people looking for the info don't have same issue.
