Difference is your one engine can get you on the plane.
Yeah, the Kenwood needs to be in the 10-15hp region.

a slight digression,

but still on the engine theme.
What difference in price am I looking t with diesel and petrol engines?
The question is general and not limited to any particular model or boatbuilder, but as an example, most of you reading this thread know that I have been looking at Redbays, they offer sterndrive diesel engines and Suzuki outboards. Presuming the equivalent power unit, what price difference is there, and can this be justified in terms of maintenance, cusmption, etc?

I've never heard anyone claim that inboard diesels with sterndrive legs were cheaper to service than outboards. Perhaps somepeople used to feel outboards were not as reliable, and diesels very simple/robust? But I'm not sure that applies - modern outboards are very good and modern marine diesels are increasingly sophisticated with electricarry to make them work.

When considering economy you'll need to bear in mind that dockside fuel prices in the CI (and France) may be quite different from the UK. Even when red diesel was avaialble essentially duty free to leisure boats in the UK there weren't many people who believed that the extra cost of a diesel would payback in fuel costs for a typical pleasure user. One of the drivers for diesel - is availability of fuel on the water; I'm not sure how much that will apply in your planned area of use. e.g. if you were planning to cruise parts of ireland and the west of scotland that may tip your decision towards diesel. Alternatively if you have petrol available at your home port it might just encourage you to spec a bigger tank.

fair comment, but I won't be using it in the UK much.

However, what would be the diff. in price for the same boat with a sterndrive diesel and an outboard?

By way of example, from the 2007 Redbay price list a given boat is quoted as:

165 HP Yam Diesel -- 44.2k
240 HP Yam Diesel -- 49.2k

200 HP Suz 4/ -- 37.1k
175 HP Etec -- 36.9k
225 HP Etec -- 38.8k

Hope that helps - prices are obviously out of date.

So,

we could be looking to pay up 10k more for the diesel. That is fair whack to be justifed by fuel prices.

Interesting thread and more interesting will be the conclusion.

don't forget that the price difference is not just the difference between both engines but there is much more work involved when fitting a stern drive then an outboard.

Yes - and what I didn't very elegantly manage to say is you probably won't justify it on that basis (alone) - but if getting 200 L of petrol to the boat for a weekend of fun is going to be a much bigger PITA than filling with diesel in the harbour then you might feel it justifies it.

Exactly! and that should make the difference in prices even more pronounced.
