My advise would be to repair or replace the engine. You will never be happy
with an outboard on a 27 footer. You would be better off with no engine
than use an outboard. Heres why: In a seaway, the engine will get dunked;
that's all you need another dead engine. Removing the engine when sailing
is possible but something most people will do once. A proper bracket to
hold the outboard on the stern will cost you a couple of bucks. Under
power the propeller will be repeatedly out of the water if there is ANY sea
running. If the engine is an Atomic 4 you are in luck, lots of parts
available and lots of rebuilt engines available.
Good Luck with your decision

I'm a newbie sailor.

We have a 27' Newport, 4 cyl inboard (Atomic?)

The engine is very dead... and not economical to repair. (Cost more
than value of boat)

We would like leave the engine as is, and mount an outboard engine to
assist with day cruising.

Could you recommend HP + how to go about mounting an outboard?

Also would we it be a fixed mount or ???

Thanks so much for any advice.
