Thank you. It was some fuel varnish build up in the carb/jet - all sorted now and running perfectly. It is also having a pre-season service by the local Mariner agent this coming week and will be fully demoed to the buyer. Who has already agreed a purchase if he has not now been scared off...
Anyone only needs to look on first page of google after searching 'tohatsu 9.8' to see your own posts about 'wont idle, rough, cutting out'. Enough to scare most people off without assistance from anyone else.
I enjoy the bit where I launch mine alongside the ragflappers tenders. They have VERY stern looks when I shoot onto the plane in a split second and take off at 20mph. Very ungentlemanlike behaviour apparently.
Now I have mine setup right, and the correct pressure in the sib it's the dogs nuts, get's two of us and light fishing tackel on the plane no worries,,love it
