Can anyone give me some advice?
For the 1st time I have developed an issue with the motor, a 1991 140hp Yamaha 2 stroke.
Always run like a swiss watch with no problems at all.
1st work the motor has done since the service last week, returning from Long Reef, when I pushed the control down
to power back to Sydney harbour the thing died after vibrating the whole boat ( Haines Hunter Centre Console ).
It chugged along Ok at low revs ( 2000 ) but any sort of pressure and it would stall.
After about 15mins of this it came good and I was able to motor in at any speed I chose. So I thought it may have been some moisture in the fuel.
I stopped in the harbour to pick up a crab trap and when I went to power off it happened all over again, this time
I was almost back to the ramp until I was able to give it full throttle without it stalling on me.
Has any one wittnessed this from an engine of simailar age?
Should I bite the bullet and re-power the boat with a new motor?
Any advice welcome...
