I'd go for a 2 stroke, cheaper to buy and less weight when your towing.

And unfortunately that is the problem! Each has pro's and con's. Here are some of the major ones:

4-strokes
Pros
Better fuel efficiency
No regular oil costs, no oil to mix with fuel
Happier sitting at tick over all day that 2 strokes

Cons
Heavy (can make stern to heavy on boat, overload transom, or cause problems with trailers/towing etc)
Lack initial acceleration (sometimes referred to as hole shot).

Old style 2-strokes
Pros
Simple engines
Light weight
Good hole shot

Cons
Poorer fuel efficiency
Need to keep adding oil (cost and inconvenience/mess)
No longer available new in Europe (except special exceptions) - so will be at least a few years old.
Not the most eco-friendly engines.

New style 2-strokes (Etec etc)
Pros
Can be lighter than a 4 stroke (but usually heavier than equivalent old tech 2 stroke)
Good hole shot
Some have 3 year service interval and automated winterising
Better fuel economy than an old 2-stroke

Cons
Not as "simple tech" as 2 strokes - some very early ones had a bad reputation.
Need to keep adding oil

What is your budget?

My boat is up for sale and the previous owner - the National Marine Aquarium used it for diving. Check it out here - http://www.boatsandoutboards.com/view/F195817

I've towed it with a Golf, A3 and an A4 no problems.

Nice one, that's a pretty decent summary of the different engines, which I didn't know before

I definately can't afford to buy a new outboard, so that will also be 2nd hand. Thanks to the people who've PM'd me as well, that's a huge help. I think our maximum budget is going to be in the region of 10k for a fully kitted boat (ie boat\trailer\engine + GPS, DSC radio, flares etc). Fuel \ insurance \ storage costs will all go on top of that, althoguh by the looks of it will be a lot less expensive than I was expecting.

Something a bit scruffy will probably do us quite well for starters, as I have my powerboat 2 licence, but no regular access for practice, and the other people who will be sharing the boat are yet to try driving any boat!

Anyone got experience of Delta boats for diving? I heard someone on another forum recommend them, but there's not a lot of info on them...

Thanks for the offer CJL, but it's a bit over our budget, and we'll probably need about a year or so to save up, which probably isn't much good to you! I'm still trying to reassure the OH that I can save for a boat and our wedding at the same time :S

One of the best Ribs on the market. Only problem is they don't or did not until recently sell to boats on the leisure market.

Most reasonable Deltas won't be in your price range either. I bought a fairly sh@gged one without a trailer and a 2 stroke engine for 6.5k. It then needed a grand spending on it to get it up to par.

If you find one buy it, love it and don't ever sell it.

Yeah, that suggestion hasn't gone down too well... hahahaha!

Sounds like I should add Deltas to the list as well as the Humber\XS's mentioned above, and teh tornados... Between them I'm sure we can find something to come in on budget. I just have to go and pass my part C driving licence in the meantime so I can actually tow the thing

Thanks for all the help - please keep the suggestions coming as they are really really helpful.
