Hello 9D280, Hello Last Tango, thank you both for responding, saying hello and your advice
Fortunately I've been told the boat has no repairs or patches, but will check all the areas you have mentioned, especially the underside as you say it has probably been fielded, or B7036* etc, it does look like the keel has a rubbing strake but will check for wear, damage etc. From the pics it looks like the transom may have some paint missing in places, I was told it had some black marks on it, just looking at the transom in the photos now I'm wondering if the black plate on the outside of the transom is normal?
I've read on here people recommending to fill the boat with a few inches of water, but not sure if they will let me do that, suppose no harm asking, do you think this would be worthwhile?
The flooring of the boat is solid marine ply, not the slatted type, so that should hopefully give us more options for seating, mounting things etc, wondering if we can fit rails/stringers etc then fit the seat frames/supports like on the Futuras and then bench seats, or would we be better sticking on the supports (not sure what they are called?) to the tubes and installing thwart seats between the tubes? Our other idea is to fix some type of bracket to the floor that will hold down a wide box that could be a combined seat and storage?
I know the engine thing is a whole can of worms, and probably if we were only going to use on the UK coastline and at sea then I think we'd definitely have a look at 2 strokes, especially the Totatsus, their 9.9, 15 and 18 are supposed to be legendary from what I've read on here... But for our use there are just too many places we wish to go that will not allow the 2 strokes, as none environmentally compliant at the lower power levels, or none we could find...
Main reason we were considering the Yamaha over the Tohatsu is the twin vs single cylinder, as we hope the twin will run smoother and vibrate less, also hoping if can get the F6A that if we wished it could easily be derestricted to provide 8hp as basically the same engine or so we believe? Hoping it could be as easy as removing an insulator from the air intake? Jets, Carb, CDI we think may be all the same spec from looking at the service manuals, but really not sure?
Really good point about the shaft length etc, will get on to Avon and see what they recommend...
Thank you both for your help
