Prop came off!!!
Today my Dad took delivery of his new boat, the agent delivered it to Port Solent to launch at the slip way.
It is a 115 Yamaha Fourstroke. Everything brand new, anyway the wind was blowing, the agent reversed in the trailer and I engaged reverse, and nothing, agent said to lower the engine even more as it was probably the wind keeping me on the trailer, plus the bunks were not helping and still nothing just revs. So I turned off the engine and was gobsmacked. The prop had come off. I hasten to add I did not catch the bottom.
Anyway the centre of the prop was still on the shaft, so was the nut and split pin, on the bit of the prop that was left on the shaft there were some groves where it looked like the outer bit of the prop slides onto.
How on earth did the prop come off, my Dad needless to say was well pissed off, the agent rang the yard and got a Stainless prop sent down and we fitted it. The boat is now on the mooring, safe and sound at Port Solent.
I recovered the prop at low tide, here is the pic. Can anyone shed any light on maybe what might have happened.
