OMC Replacement?

[garonsgoons]

looking to replace the 1985 OMC 260 hp GM 350 V8 Stern Drive in my 27' Chaparral Cabin Cruiser. Would like to replace with a more fuel efficient engine without major changes or remortgaging the house. Any one got an idea on a good replacement?
thanks

With a 27' boat,......... What you've Got, is about as Good as it Gets.......

The best way to improve mileage is to reduce weight in the boat and consider repowering with a duoprop. I've found that 3400 rpm was the sweet spot for my older 5.7. This took me up to approx 37 mph using a 15X15 prop
