I'm not taking it personally Kris. Just opening up discussion. My Boat came with a Honda 10 from 1985, my last boat had one slightly newer, 87? Bomb proof. Just sold 1 3/4 engines for good money. Your other points are correct, but I'd suggest transport of fuel to service station would happen by whatever fuel is appropriate. I get it by foot with my little trolley usually. Would strapping a big 50hp outboard with a high thrust prop on the back of your boat work though? If not why not. Setting aside whether you would want or like it!
Then you could keep the Ruston polished and painted for the historic tours. "This is what powered the boat in the olden days".

"This is what powered the boat in the olden days". setting aside the asthetics of strapping an outboard to the back of an historic boat I think you are missing the point. A petrol ourboard would burn much more fuel causing more pollution so what would the point be? yes Honda outboards do last longer than most but 50 years? And still be going strong? Watch out for the paraffin fumes I have friends who have seriously damaged their long term health from using it and not from doing it wrong or accidents but just from prolonged exposure over time. Oh and I don't polish my engine, it's a workhorse like the rest of the boat it's meant to be functional.

Re fire breathing, yes well aware it can be lethal, chemical pneumonia if the paraffin goes down the wrong way, also from the soot particles. Which also arises just with fire manipulation, juggling, staff twirling etc. When I've taught it I start with the risks involved. Getting burned is the smallest risk. I only do one or two fire jobs a year.

Anyway this gardner sold for Β£6950 so there is still a market for vintage engines it seems.

only just got round to reading this thread (been having crap internet reception lately)
Very interesting discussion ....... some food for thought

Particulates etc from diesels in boats: Over recent years I have installed several small 4/5kW diesel generator sets. Something I have notice is that the exhaust from the raw water cooled sets that went through a gas/water separator always smelt and seemed cleaner. It was also a lot cooler, almost air temp.
I am wondering if just washing the exhaust from vintage engines could heavily reduce the nasties.

I am wondering if just washing the exhaust from vintage engines could heavily reduce the nasties. I believe there were experiments with "washing" the exhaust gasses from commercial vehicles to get rid of the fine particulates but I understand there was problems with disposal of the heavily polluted water from the system. Water cooled exhaust systems on boats definitely seem cooler and cleaner (Shapfell has a water cooled exhaust) and I don't see why it wouldn't work ...... trouble is if enough engines were using it would it cause serious water contamination problems instead of air pollution, or are the numbers of boats small enough not to make much difference.

Oh, I like old engines in old boats Kris. The reason I don't have an old engine in Sabina is mainly because I was made an offer I would have had to be mad to refuse. (The Daewoo I have fitted is quite an elderly design (MAN) and is long stroke, normally aspirated with rev's of about 1400 giving about 7 kts)

I value your opinion john as your one of the more level headed ones on here.

I don't know the answer to that John. I wonder if the particulates would drop out into the mud. When one thinks about it I suspect that most early engine were raw water cooled. I was thinking about a gas/water separator as it seems to remove more than a it seems a straight raw water cooled system. It also has the advantage the water could be discharged below the water line and the result is a much quieter engine presence as well.
