when struggling with the beast
while grappling with the beast I researched all sorts of ideas for sticking with the slug
outboards are cheap enough to not have to bother with lawnmower engines
there are so many great second hand ones hanging around
I currently have four functioning outboards

I always find modern outboards relatively expensive
do you have a good one for the yacht now?

In the early seventies a neighbour and I purchased an 18 foot plywood cabin cruiser to use on the Thames and the local canals. It had an 18hp Evinrude twin. This was always oiling plugs as it was not possible to get it going slow enough. A work collegue had an outboard which he said we could try, and if we liked it we could buy it. I cant remember the make but it could have been the one in the clip, except it was white. I am sure it had a " Tecumseh" engine-a sort of American rival to B&S with a picture of a red indian in full headress on it. I believe Tecumseh was an indian chief. Just like the one in the video it worked faultlessly, went pretty good, was light on fuel-especially compared to the big Evinrude-but was too bloody noisy! We politely said no and found a 6hp Evinrude in a swop/cash deal that was benificial to us. On the Internet somewere is a small diesel from China mounted on an outboard-that may solve all Dylans problems -if he can stand the racket!

Outboard
Katie L engine stick is pretty healthy at the moment
I currently have the Honda 2.3 4 stroke - sips fuel but is noisy
A yamaha 5hp two stroke - light, reliable but two stroke
and johnson 6hp twin - two stroke - heavy, quiet as a mouse, smooth, powerful - but two stroke
a Seagull 4 hp long shaft - completley unethical
so the answerr is that I have an outbpoard for creek crawling with the little Honda
I do have a two stroke I could use out of the estuaries
but I really want to buy or blag one of the engines we tested on the lake

but the press and web person at E P Barrus will not respond to my emails
despite my promises that I can widen and deepen their digital footprint

Honda produced an 'outboard' which had a standard GX type engine mated to a fairly conventional outboard leg. I've tried to buy 2 on Ebay and failed both times. They are reputedly pretty heavy.
Even better I do have an Atco Boat Impellor - which is a genuine lawn mower engine mated to a long shaft - just like the Thail long tails. It is a whole three quarters of a horsepower.

Two years ago I had every intention of grafting a spare B&S 3.5HP onto a Seagull Silver Century Plus leg, which in theory would have been a perfect combination.
But - before making-up an adapter plate, I thought it might be a wise move to direct the B&S's exhaust underwater, just to check how quiet the engine would become in that scenario.
The result was that the noise from the exhaust was indeed significantly reduced - but reducing the exhaust noise exposed the racket from the rest of the engine (which the exhaust noise had been masking) - it was terrible. I held my head about 18 inches away from the engine for 5 mins or so, and got myself a blinding headache from so doing.
So the brainwave was abandoned.

Anybody remember that awful inboard / outboard contraption that Seagull cobbled together? I don't know anybody that had one and kept it. There must be a lot of them littering the seabed in places various.

I believe one of our fellow forumites designed it
Can't remember who though, probably fortunately.Pete

Seawitch
Rebeccas Seawitch - still undergoing repairs - has a hole in the bottom for just such a contraption
pleased it is no longer there
reverse was engaged by reversing the polarity of the engine I beleive
terrible corrosion circuits established as well

Well Dylan - you may now have to re-evaluate your prejudices, as I believe you were in favour of using a diesel engine on The Slug (if only it hadn't misbehaved) ?

And for those who can't be arsed to click on that link - Diesel Engine fumes are now conclusively known to cause lung cancer and perhaps bladder cancer.

Couple of other types did that too - Dolphins for instance. No gearbox, to go into reverse you move an electric switch which kills the engine, and means that when you start it again it spins up again in the opposite direction.
I believe large ship engines often work the same way, albeit with compressed air starting rather than electric.

They were fitted with FNR gearboxes.
The basic concept was sound - but the installation of them was simply plain stupid: leaving (what was effectively) an outboard leg in seawater 24/7/52 without any anodes - crazy.
Should have been installed in a removeable cassette in a well, so that the whole unit could have been pulled clear of the water when not in use, or to perform maintenance.
