Tom,
I have been watching your other posts as well as this one and it is pretty
clear you are in the beginning stages of consideration for boat ownership.
I'm going to lay out some facts of life you probably won't want to read, but
do need to know.

1) Building a boat is not cheaper than buying one.
2) Owning a boat, using a boat, insuring a boat, establishing a place for a
boat is expensive.
3) Boat maintenance will take most of your free time.
4) If you are married, a boat will be the least popular thing you could
undertake with your other half.
5) The boat hull is 20% of the investment.
6) The majority of boat building attempts fail. The larger the boat, the
greater the failure rate.
7) Number one reason for failure in building is underestimating the total
cost in both money and time.

There are more, but your posts indicate to me that you do not have the
available money, the skills or the tools to either build or own a boat in
the class you are considering. Building a boat is very rewarding and I do
not wish to discourage you, but reality is alive and well. My advise to you
is to build a small day boat first. Get your feet wet. Failure is affordable
and success is just as sweet.

If you know a good site for info about this part of boat ??

Or, can you explain it here.

So far I know ,,,, hole in boat for shaft to go through from engine. Is
the cutlass bearing what lets the shaft turn and not let the water in?

What and where is the stuffing box?
