Air cooled.

I'm assuming air cooled as this is simplest for an engine. However, it
may be noisy and need access to ventilation so belowdecks may not be
ideal.

The noise will be minimized since we can optimize the induction/exhaust
system for one fundamental frequency and amplitude. However, you are
right that it will make noise and require ventilation. I am
particularly concerned about exhaust gases. A built-in system would
almost certainly be more expensive to design and support, so we'd need
to see sufficient demand to justify it.

My preference would be for an integral tank that gravity-feeds the
engine. This is simplest and therefore cheapest. You can always use it
as a day tank and fill via dedicated line from the main tank, or rig up
a float switch to kick in a pump.

Does the higher profile of a gravity-fed system matter to you? Where
would you envision operating such a system on your boat?

Thanks for the feedback.
