Considering this since i definitely have the hatch room. Or do i consider just putting in some high horsepower 2 rear engines?? I realize any option the includes eliminating 1 of the motors will more than likely require a drive upgrade, as it will take more hp from 2 engines, to run as effectively as it did with triples..... Any input on anything would be great
Well it comes down to what you want, it will cost you $$$ either way and you will NOT increase the resale.

I would leave it tripple before having a high HP Side by Side.

Cons to a tripple is:

1) Tripple everything, Oil, belts, etc
2) Harder to work on
3) Hard on the center Drive and Hard on the center Prop.
typically run a right hand drive and prop on the center
because they are easier to locate parts etc,

Center Drive works the hardest and is at risk the most due to it's depth.

Pros:

Looks and sounds cool as heck!


Side by Side:

Easiest conversion, but if you UP the power, probably should put on better drives.

Pro's:

1) Only patch center hole in the transome
2) One less engine and drive to maintain
3) Lots of front space in the engine bay.

Cons:

1) Big power in a side by side to equal a tripple
2) New drives
3) May not meet your expectations for speed

Staggered Twin:

Most work, but also the most benifits.

Work required, redo the transome, redo the stringers, redo your engine and drive rigging.

Pros:

1) Two engines and drives to maintain.
2) Room all the way around your engines to work on them
3) Lower center of gravity for better handling, ( Engines lower, boat is higher )
4) Only need 50 hp. more per engine to achieve the same as the original tripple set up.
( tripple 600's = Twin staggered 650's ) John Pompi master engine rigger shared this
with me years ago on a conversion he did.
5) Boat's most efficient and fastest set up.

Cons:

1) $$$$$ and time for your conversion, granted you can sell your third set of hardware
to help offset the cost.
2) New drives to do it right
3) Loss of cockpit space ( If it were a new boat )

Hope that helps
Jon

I'm converting a triple 42 Fountain now to twin staggered, you can have Vincent do the stringers and transom. It's cheaper that one would think.

How did you guys end up with the boat after all?

My guy told me $3,500 - $5,000. He's done them before.

Yeah...one of the outside ones should be LH rotation. Which one depends on if you would like more bow lift.
I can't believe it does not pull to one side. It will ride better and dock much easier as well.

Does not pull at all, docks easier then my 1 screw did. I thought 2 screws is were you would notice the most. I am curious to see the difference, just not curious enough to hang a LH on it.
