3rd outdrive adds a lot of drag
I was wondering about that and figured I'k like to ask you guys...
If you were shopping for a 40-42 footer, ( not 47 I know triple is probably mandatory), and you had the choice to have, let's say:
3 x 500 hp
2 x 750 hp
I know bravo would strip with 750 but what would you choose and why? of course one of my main question is fuel economy, and reliability...
So you choose???
Twins for power to weight and balance of boat.
Best would be staggered.
I forgot the formula but years ago some told me for the same performance in theory for a vee.
single 1000hp = twin 600hps = triple 500hps
of course there are alot of other factors
No Beak, No Bustle, No Bull. Donzi 38 ZRC
2-750's. And BTW, I would never run Bravo style drives in a 40-42. Best bet would be Merc 700's with NXT's.
why the smiley don't work anymore? It's the 2nd time i put one lately and all I get is a :d???
any comments by triple owner?
Triples became popular back when gas was cheap and Bravos weren't as sturdy. Look at a boat like the Cig 46- if you want the fast one, it's 1200's on 6's. A few Apache 47's have been recently re-rigged from triples to staggered monsters.
The weight/drag is tough to overcome compared to the new hardware available.
You'll go faster on less fuel with the twin, assuming equivalent horsepower- as in your example.
I love my trip 525's! 90 mph w/ light load. Gas from anywhere, get repaired anywhere. No fussy blower motors(have had very bad experience w/ 575's) Drag & weight , sure, but reliable and in northern Michigan, don't need down time in the middle of our short summer!!!! Had an issue this last summer (not engines) and limped home on 1. Glad I had 3!!!!!!! By the by, I do not have a lighter layed up boat where 2 engines would do better w/ at this size like Jassman's 43 NT!
