9.9/15 hp outboards

        Having recently purchased a 15 hp FORCE outboard this thread
interests me.  Here are some specifications I picked up at the boat show
in Winnipeg last month

        Merc 9.9, 12.8 cu in.  210cc  bore/stroke 2.31in x 1.77in

        Merc 15   16.0 cu in.  262cc  bore/stroke 2.38in x 1.80in

        Suzuki DT 9.9  bore/stroke 2.13 x 1.81in  211cc

        Suzuki DT15C   B/S 2.32in x 2.05in        284cc

        Johnson 9.9 & 15  B/S 2.375 x 1.760in  255cc


        FORCE 9.9 & 15  B/S 2.25 x 1.94, 15.41 cu in, 252.5cc


        From these few stats it would appear that the 9.9 and the 15
have some specific differences, and that theres more to upgrading to
a 15 than removing a bolt.

        FORCE outboards are Merc clones.  Does anybody out there have one?

Any comments about this motor's performance reliability etc. will be

appreciated.

                        Thanks  Rick

Are you sure you're not thinking of Mariner?  Unless something has changed
lately, Force outboards are different from anything else (except perhaps
the old Chrysler outboards on which they were based, but I doubt there's
much Chrysler left after all these years).  Mariner and Mercury are both
built by Mercury.

There is a little connection between Force and Mercury, if I recall
correctly:  Force is owned by U.S. Marine, the parent company of Bayliner,
but U.S. Marine was purchased by Brunswick, who also owns Mercury (and a
sizable number of other boatbuilders).

Bill recalls correctly, although the connection is gradually being
strengthened.  For example, the Force 70 uses a variation of the
gearcase and intermediate housing from the Merc/Mariner 70/75/90.

Mercury and Mariner outboards are for the most part identical now,
although many of the older Mariner models were made by Yamaha.

There is still a _lot_ of the old Chrysler design left in most of the
Force models (5, 9.9, 15, 90 and 120 in particular).  They are fairly
good motors, though they are not nearly as refined as most of their
current competition.  They lack:

  sound deadening.  They are louder than many more recent designs,
  though quieter than the older large Mercury in-line's were.

  oil injection.  They smoke and foul plugs, but are simple.

  Loop charging.  They have less power for their size, though their
  hole shot is frequently better than the newer designs.  They also
  use more fuel at high speeds than the newer designs.

  Through-hub exhaust.  (Except for the 70.)  Through-hub buys you
  better hydrodynamics, for a higher top speed.  It costs you thrust
  in reverse, though.

I also don't think they are as well built as some others.  On the plus
side, Force motors are quite simple and basic.  I have worked on a
few, and they were generally easy to work on.  My father has a 9.9 or
15 (same basic motor, different details).  After several seasons of
running it through the muck in his marsh he hasn't had any major
parts fail, although a couple of small parts have worn out.  It has
never made him row home, and its power and speed are comparable to
the Evinrude that it replaces.  It may be a touch noisier than the
Evinrude was, but it also weighs 10-20 lbs less, which is a big plus
when you're constantly putting it on and off of the boat.

I came very close to purchasing a used Force 125 myself a few weeks
ago.  I can easily live with the Force's (minor) deficiencies in
exchange for their much-lower purchase price.  They're not for
everybody, though.
