Oh dear, my last boat, a 23' sports cruiser did 2.25 mpg cruising at 30 kts with an old 5.7 litre V8 Volvo + duoprop.
Surely the "modern" outboards can do better than this?
Whilst on the subject, I shall be taking delivery of a new RIB in May 2006 - Can't do this year - I am committed to major DIY between now and Christmas!
I am currently thinking of an 8 metre Humber with a 250 hp outboard and 70 gallon tank (plus a further 18 gallons in a reserve tank). But what 250 hp engine is likely to give me great performance and run on air? Well OK, a small amount of fuel then!
Should I be looking at the E-tec or a 4 stroke. If the latter, what seems to be the best at the moment? Alternatively, even if the E-tec uses the same amount of fuel as a 4-stroke, how much oil would I expect to use and at what cost?
I've been off the site for a few months, having cancelled a RIB last year, for medical reasons. But now I'm back
I look forward to hearing from you!
