Or, if you can wait till spring, I may have an M25 that would suit you
well - it's too wimpy for my 36-ft sailboat, but would push a 27ft-er
just fine.

For a 27' sailboat you are limited to a 9.9 hp Yamaha or Honda with the
high-thrust gearing and prop. The mount should be a retractable designed to
take the power and weight. Cheap mounts wont cut it. The transom will probably
have to be reinforced to mount the motor.

The disadvantages are that horsepower is a little low for a 27 footer going
windward in a stiff breeze and a chop (more powerful outboards are geared and
propped for planing boats and not a displacement hull like a sailboat), limited
battery charging capability (~10 -12 amps is about it), and in any kind of a sea
the prop will tend to come out of the water (potentially over speeding the
engine).
And you aren't going to save that much money:
outboard $2300
mount $200
transom reinforcing $100-300 (you doing it or paying someone to do it)
Tanks, lines, misc $100
total $2700-2900

For that kind of money you are at the price of a remanufactured Atomic4 with
upgrades like electronic ignition, etc.

There are LOTS of 27-footers with outboards: I had an outboard on my Cal
25. Never had it swamped, but prop-out-of-the-water was a problem. MUCH
cheaper than rebuilding or replacing the inboard, though!

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.
