Can anyone tell me the benefit to put a third drive into a 42'boat with the same engine it is now equiped ? so you get a triple drive.
What will happen with speed ? Performance ? etc.

over kill,a stagered twin will run the same speed with the same power!

3 x times maintenance, 3 x drives to worry about if you hit something... 3 x engines ::: fuel...
If the budget is'nt a problem... why not?

what power and drives do you have now? speeds? big trips are pretty awesome, but haint the easiest to keep running
and in all fairness its not THREE times anything unless u plan on putting a single in a 42

I have read that "true offshore" boats use triple engines and drives and are propped to go on plane using only 2 motors so if you were running to bermuda or something and 1 broke down you could come back without idling for 18 hours,Smitty

3 drives look kewl!
My buddy has a triple engine 42 Fountain. Some guy was looking at the 3 blower motors and asked "So, how many outdrives does this have?"

Here's your sign.

Go with a Cary and get quads, then you casn go to Bermuda on 3 instead of 2 if one breaks.

even if u dont go much faster, they still look badazz, not to mention nice exhaust tone and wake.........
old school offshore boat- (heavyhull+bigpower=speed+noreliability )
Speed > reliability

I guess I'm old school...

I know have 2 volvo SX drive's with 2 tuned up 350 engine producing 420 HP each. What would do a third engine and drive ?
