Mounting twins on a Phantom 25

Hi!

I will mount two Merc 2.5 SS engines (260 hp upgrade to 330 hp by Michael Werner in Germany) on my Phantom 25. I can choose between old style cowlings (square like) or new style alien cowlings.

With the new style cowlings the engines has to be mounted 23 inches centerline to centerline. This is equivalent to two UK Phantoms running twins (one Phantom 25 w/2xMerc 2.5 SS and one Phantom 23 w/2xMerc 2.5 SS).

With the old style square cowlings the engines can be mounted approx. 20 inches centerline to centerline.

The Phantom 25 is relative narrow, and the beam is approx. 170 centimeters.

What is the antvantage or disantvantage of mounting the engines 20 inches vs 23 inches?

Cheeers and thanks!

With 20" centres your tie bar will be cheaper!

Hope that helps!!
