Im looking to buy a 18ft Fletcher with 3.0 engine - can anyone give an idea of what fuel consumption might be please
Thanks

Assuming petrol and carbed, I would have thought around 25 litres per hour once on the plane and not going flat out.

Thanks for that

I think you will find it will average about 1l per mile over the season. Geoffs had a 19sportcruiser for a while so he should be able to aadvise exactly wot it cost to run

Yep, I can confirm what Steve says. About a litre a mile overall. Will vary depending on speed sea conditions etc., and assuming engine in good shape/tune.

Most economical cruising is 3000 to 3500 rpm when boat speed will be 20 to 25 knots on a flat sea. Flat out at 4500 rpm will be about 33 knots.

The 18 very similar to 19, same hull, but different top side styling and interior, great boat.

Watch out for head gasket leaks, raw water to out side of engine, you'll see tell tale white/rusty streaks down side of engine. Also leaky water pump on front engine, which rots steel timing cover on the front, and also sump.

Mercruiser 3.0ltr. A super little engine, quiet, smooth, quick and economical. Easy low cost to repair service and maintain.

If looked after, will plod on for years and be extremely reliable.

I can confirm the mile per litre figure in my case on a 21ft Bayliner. Great little engine (so far).
