Single vs Twin engines
I am looking at getting back into boating. I used to have a Scarab with a 350. First off I will be only doing freshwater on the highland lakes in central Texas(Travis and sometimes Canyon Lake). Aside from some obvious benefits of a twin(extra engine if one goes down, more power, easier finesse turning around the dock) what other benefits am I looking at? Also, the downsides(twice the gas, maintenance and weight). I am looking at another go fast but also a cabin cruiser, neither over 30 ft. Any input would be appreciated.

I think the maintenance issue is a catch 22. Obviously its less to maintain two than one, but on a heavy 28ft boat the cost can be less overtime to maintain two motors. A heavy single engine 28ft boat will go thru motors and drives much faster than a twin. In the long run I think you may find it cost more to maintain a single high performance 500hp+ motor and drives than twin stock 415hp 502's or 365-385hp 454's on a heavy 28ft boat. In short, assuming a single engine 28ft boat has 500hp+ it will have shorter rebuild time and cost just as much to refurbish than a twin engine stock setup. Gas on a single vs twin is about 25-33% less, not the 50% you might expect.
Balance is also a catch 22. The torque steer of a single engine sucks much worse than a heavy rear ended twin setup IMO. There really is no free lunch with either setup on a big heavy 28ft + boat. |

Also, if you break down with one engine you are being towed. That can get old. On smaller lakes not a big deal but in big water lakes/ocean different story. I run a 28 single with 675HP and an IMCO drive. |
Depends also on the age/condition of your motors. Older motors and drives will break your bank. After having both I'd never to back to a single, I will however make sure that my next boat is newer with low hour/age motors.
