I don't know if I would call either one "rare", the right-hand-propped
inboard, which is quite common, requires a reverse-rotation (ccw)
engine, and the left-hand-propped inboards are a little more
straight-forward to do an automotive conversion job (still have to have
corrosion issues and spark ignition issues, & carb venting &
construction, all addressed).

When looking at rebuilds or new blocks, there is a $100.00 to $250.00
premium on the ccw engines.

Most stern drives have a standard, cw rotation engine.

In our ski club, we have many Malibu's, Master Crafts, Correct Crafts,
Tiges, and Moombas...all are cw. The only exception, is one old
Natique...driver sits on the left side.

I don't know of any modern ski boat manufactures, that put ccw engines in
their hulls.

The premium for ccw engines, is for the reverse cam and oil pump. And
outside of the (pointed) distributor, and flipping the body on the pick-up
pump, everything else will work.

You say "most stern drives" are cw...I have never even seen one...did some
one make one at some point?

Later.

Correct Craft uses a ccw(reverse) engine, right hand prop(driver on the
right... "Correct"). MasterCraft uses a cw engine, left hand
prop(SHOULD have driver on the left)... take a look.

All standard Volvos, & Mercruisers, Alpha & Bravo types, use a cw
(standard) rotation engine. The upper gearcase gives a right-hand twist
to the vertical shaft (Alpha types - viewed from above), resulting in
the forward gear in the foot providing a cw(right hand - viewed from
rear) twist for right hand props in forward gear(back gear in foot
provides reverse).

Cone-clutched I/O's (Bravo & Volvo types)can have Left or Right Props -
the vertical shaft changes L-to-R for reversing.

Inboard cw engines "pitch" to the right when in reverse...the driver SHOULD
be on the right, to accommodate docking and other slow moving maneuvers.

If Correct Craft puts a ccw engine in, and puts the driver on the
right...well...that's just ignorant.

Anyway...thanks for the info.

I know they *can* make them spin right-hand, as most dual drives are
counter-rotating. My query was there ever any i/o manufacture that used ccw
engines.

Of course, I probably wasn't clear to begin with... :)

Here is your confusion... cw (clockwise) IS right-hand rotation - OF THE
ENGINE... as observed from the water pump and pulleys end - as intalled
in the family car or truck... this results in a left, or Left-hand
turning prop in a straight inboard as viewed from the flywheel end.
This is the MasterCraft and Mercruiser engine layout. This will result
in the driver being on the "incorrect" side of a straight or v-drive
inboard based on propellor thrust, which would cause the boat to twist
opposite the prop, or clockwise looking at the transom, and adding to
the driver's weight for a list to starboard.

In my time in the ProStar though, I never really noticed it, except
backing must be done on the opposite side from our Correct Craft. In
reverse, the transom walks right on the MasterCraft, left on the Correct
Craft and Century (Coronado).

Spin-outs have to be done in the opposite direction, too.
