Looking for clarification here.....I am trying to classify a hydro (rigger). Has two .12 or two .15 motors, actually as I am looking at the rule- two .21's will fall under the minimum size engine requirement. Does this allow the smaller displacement motors to run in their respective displacement of hydro not under the "twin blanket"? I guess two .12 engines would be just larger than a "B hydro" so it would fall in the c class?
IMPBA Specialized Nitro Classes page H-13 specifies "Multi-Engine Hydro
1. The hull will be a hydro as defined on page K-6 of the Rule Book. Under the title of Hydro Hull Definitions and Restrictions
2. The boat must have a minimum of 2 engines.
3. This will be a Nitro/Glow only class.
4. The boat must have each engine connected to a shaft/propeller or the boat may have a minimum 1 shaft/propeller so long as all engines are connected and driving the 1 shaft/propeller or the boat can have multiple shafts/propellers so long as all shafts/propellers are connected and driven by an engine or engines.
5.
The
minimum displacement for two or more engines will be 0.610 cu. in.
or 10cc.
The maximum total displacement for two or more engines will be 1.830 cu. in. or 30cc.
