Small shallow skiff type mono hull power boat for a single person. Before Jetskis were a thing!
Boat sits in a steel tube cradle for storage and travel. See photos.
Cradle with boat fits into an open ended 6' x 4' trailer. Cradle can be fastened to a trailer with bolted brackets. Couple of ropes or ratchet straps to hold boat in cradle for travel.
Boat can be lifted from the cradle and placed into the water by two capable people.
Motor is started with a wrap around pull cord (ignition turned to on). Boat can be held stationary by helper while motor running at idle. Hang on to steering frame, pull start cord then go... Sit down and adjust throttle for speed. There is a kill switch on the steering wheel that can be held down to replace the normal ignition switch. Let go, the motor will stop.
Slow down and switch off motor to stop.
Fuel tank is accessed under a removable panel in the rear. There is a simple hand lever operated mechanism that allows the rear hatch to be lifted with the other hand.
Fuel pump is located under the steering frame. Motor carburettor can be manually primed before starting motor.
Cavitation plate at rear helps the boat get up onto the plane at speed. There are two sets of optional side strips that screw on that give a bit more lift at speed to assist getting up onto the plane.
The boat is stable at speed and feels fast as you are sitting at water level.
Boat hull is 2.38m long. Cavitation plate adds 250mm to length.
There is a manual for the motor bike that the motor came from that is included.
Happy to chat about more details if you wish to phone.
Boat and cradle will need to be collected from Eltham Victoria (I'll need your help to lift them out of my workshop). The motor has not run for some time. The bearings and shaft log all have clean fresh grease.
Rego was paid at the end of December 2025.
