I have a friend with a Bombard 6.2M with 90HP E-TEC. I will ask him about fuel consumtion figures but I know it is very good. It also looks fantastic! One of the best looking outboards evermade in IMHO.
I had a 75hp fitted to my 5.5m, e tec that is -- use it as a safety boat, great engine, would rec it to anyone, low fuel, high oil price, but it uses hardly any, and as you say a great looking engine, and lighter than a 4 stoke -- get one.
I have done 140 hrs since last March and am getting around 1.7 nm per litre.
If memory serves me right I have used about £60 oil for the 140 hrs or so little that it doesn't really matter.
It has loads of grunt, will pootle along at low revs no problem but will shove my boat along at 32 knts when required (swinging a biiiiig prop)
It looks pretty good and I still have over 2 years warranty and 2 years before I have to fork out for a service (except I will probably get a 'mini service' done anyway)
I have had excellent service from my local Evinrude agent.
I like it so much that if I buy another boat I will buy it with an etec engine or a bare boat and get it fitted myself.
Regards
Robin
PS...forgot to mention...some mates have a 75 etec on a Valiant 520 (?) excellent engine, goes like stink and sounds good too!
