Yamaha 225 loss of power
Just a quick note in case anyone has the same problem. We have a yamaha 225 which has always run perfectly but then over the winter developed a problem. Basically, it would run fine up to around 3600 revs, then it would lose power gradually and drop down to about 3200.
We had a yam engineer look at it a number of times and he couldnt find the fault - v frustrating given the great weather up here. Eventually he found it - we inherited the engine with a fuel flow sensor attached and it turns out on inspection that it was dry. We removed it and engine now happily runs at 5200 revs.
Probably pretty rare, but thought i would post it just in case anyone has the same quandary.
