Ok Rick, good question.
What I was trying to say is that it is no good putting the outboard
out at the far stern of a boat that is designed to pivot at approx 2/3 of its waterline length, the prop will come out of the water
and over rev. in large seas. The pivoting point of the boat has to be much further back like it is with a planning power boat
, so that the props stay in the water
There are many outboard powered Planning boats that are very safe in large seas. The problem is they use too much fuel to be suitable for cruising.
There is a schionning cat that sucessfully uses outboards.
with a wide stern is designed for outboard power either gasoline or Diesel (Yanmar)
My point in general terms is that outboard power has improved tremendously over the last ten years or so.
Four strokes are quiet, fuel efficient and very reliable with a much longer service
life (if you buy Japanese)
They are also light weight and much cheaper than diesels and very very safe if set up properly.( In spite of rhe unrealiable,misinformed information that comes out of this forum sometimes)
Outboard ripped off the back of boats??? gasoline tanks blowing up for NO reason.???
Diesels are heavy, expensive, and are only reliable if run under load most of the time. (which does not happen with most sailing boats).
Most diesel motors I have had in Yachts had a dismal record
because they were not used properly. (under load) Technology wise, they really have not improved either.
All that said, I am not in favour of gasoline inboard motors unless set up with Bilge
blowers etc running continuously.
