Surely the 115 cant be as thirsty as the twin 60's though, cant it? One of my main reasons for thinking about the change is the possibility saving of some fuel at cruising speeds, though i know it wont be significant. The other is that my other half has small hands and so is finding the twin side throttles a bit difficult to use.
I was hoping to get around the £1,500 mark for each. As i said they both have lots of history and have side mounted Quicksilver controls, rev counters which have hr meters in (though i dont believe the hours are right) and new props this year, (one is a recon the other a mercury black max), but i would have to be able to sell both for that amount to be able to get the Yammie.
Its a bit higher than what you said so i think the idea may go in the back burner until more funds appear.
