rexx,
this is really exciting. a few thoughts: 1.) there is always the turndown pipe option for idling/low speed noise reduction. 2.) as a strategic excercise, reverse your chronology on engineering challenges; since it seems that you've got the bascic powerplant issues solved or have the ability to solve them, spend most all of your initial energy on the ancillary systems- cooling water delivery/pumps, hydraulic systems/steering, adequate electrical systems/charging, marinized fueld management/delivery and filtration, engine mounting, placement/ x dimension considerations, quality air delivery and backfire prevention. etc. etc.if you were to run into engineering or financial challenges you'd know it before you made the whole leap - keep us posted - jeff
