Twomixdiver:If you are using your boat in open ocean I would suggest halving your 150HP engines into dual 75HP. If one conks out you can still limp back home on the remaining engine.
If you plan to technical diving (i.e. twin tanks, stages, etc.) a 19 foot boat may be too small for six divers, and perhaps dangerous in heavy seas.
I agree, go twins........and bigger. You also want something with a sharp V-hull to cut through the waves, instead of slamming you to the floor everytime you go over a wave. Needs to be high out the water.
