No, it's not essential. If you plan to carry one, depends on the size of the boat. It would be useless with a larger boat as it wd need a monster outboard to move it anywhere. Decent saftey gear, radio and engine maintenance/spares should make it irrelevant, imho.
But erm...i was badly backwinded in a 40' sailingboat near a cliff, and got our kids to tow us off with a 6hp dinghy positioned amidships and lashed fore and aft, boat steering to dinghy, dinghy driving towards boat. Very effective.
hmm, as tcm sez, proper maintainence and spares should make it not needed, my previous boat was single deisel, kept the fuel looked after with some snake oil, kept it serviced with filters changed and it was 100% reliable, a chap Iknow of with a similar 23 foot 2 ton boat has a outboard bracket and a 10hp, he say lifting a bigger one would be a no go, it makes hisa boat do about 5 knots, but limited range less you carry loads of petrol and as soon as waves are bigger than 1 mm progress stops although helps with steerage.
as unconclusive as tcm, depends on you, your boat, your maintenance schedule, spares, your cruising ground, how au fait with spanners etc...
<hr width=100% size=1>Sod the Healey - I think I'll buy an E-Type.
have to agree with the others - essential no. The only real thing it will offer is peace of mind. On my last 16'er, I had a 4hp aux to my 50 hp main, which was no real problem since both was petrol but in 2 years of quite regular use it never even got fired up (apart from once when I played around in the river). I now have a single diesel and carry all belts and filters with necessary tools, resigned to the fact that I will need to call for help in the event of a problem.
Well I've heard what the others have said. But I've got two engines. One day I was crossing Lyme Bay, quite rough. One engine stopped. At first I thought, bugger it, I can manage on one. In the end I desided to mend it. So changed the filters whilst rolling around in the engine room. Started it up and all was well for about three minutes, when the other stopped. No amount of changing filters would mend it. So carried on on one. Turned out to be a leaking union on top of the fuel tank.
On another occasion I had two drive failiers within 100yrds. But thats a long story.

The point is. It's rare I know. But you can have two engines stop, let alone one. Ask TCM and he has a new boat! Besides you only need a rope round a prop. Or a prop falling off. Its happened to a few. So need outboard IMHO

surely anything much over 23' is going to need at least a 9.9hp to make it worthwhile - unless you're only ever 500yds from the shore / marina ?? and that 's a heavy peice of kit (and then what about an aux for the aux
