Now my keyboard's broken!!
My engineer is pretty knowledgeable and does a lot of write ups in the mags and most people round this way can't rate him highly enough so will stick with him for now, I've had it idling perfectly in the wheely bin this morning and will try it in the water one evening this week.
I've raised it as high as I can, I think it still looks a little low compared to all the images I've seen but I've run out of holes on the bracket and transom so it will have to do, if it improved half as much as it did last time then I'll be very happy - but I will have to build up the transom to support it.
If I move the pin then how do I set the trim to know where it is - so the gauge is correct?
