New rib still keeping me up.
Quick silver 410. 30 hp tohatsu Efi
well I tried the new rib I bought on a popular English power boat testing lake yesterday 23rd dec.....and the engine being set 61mm too high ( cavitation plate set above keel line height) made the boat.................... Pretty bad, ventilating straight away on the plane, unless engine is trimmed fully down.
I intend lowering the motor 65mm with a jacking plate type block i will machine, with a set back of 100mm to clear the clamps from the transom. I will mill the blocks from solid Ali, and bolt it on to the existing holes in the transom and motor. I think lowering the motor 65mm will not drown it. The motor will be mounted on its middle holes so I can fine adjust it up or down a bit if needed.
Is there a fancy prop that will work with the engine set as is?
