> Does two 8's make 16?Roger, I hope to see the FLS in plywood soon. It looks rather nice
in the 3D representation. But it would be nice to see it with crew
I've often wondered how two OBs compare to one. On a larger boat
where the weight would not be so much of a factor would 2 50's go as
fast as a single 100hp. Or would drag, turbulence, or something make
it perform something less than 100hp. I'm guessing 2 outboards have
more grip and therefore perhaps more power for towing or for pushing
a heavier boat at low speeds. Maybe maximum speed is attained
quicker, even were the max speed less than a single ob of the same
But I speculate WAY beyond my knowledge.
In this particular instance the two 8hp's would make a really heavy
fuel inefficient 16 (providing I find a prop). And the tiller
steering would really be a pain. Although now that I think about
it, tiller steering for twin outboards might lead to some
interesting setups . . . .
I'm going to pass on the motor. My 8hp Johnson pushes her neat and
leisurely. I don't want to spend so much time learning about and
working on outboards that I neglect boatbuilding and fishing. I'm
adding on to my home right now, and let me tell you, not being able
to get out and play in my new AF4 is KILLING MY SOUL!!!!
- A single 16 hp will push a given boat faster than twin 8's
and use less fuel and cost less money to purchase new.
Twins do offer the safety of redundency, and might be no
more expensive than a single 16 plus a 4 or 5 for emergency
use, plus a single 8 will be better than the 4 or 5
in an emergency.
Jim and I ran our AF4's yesterday and today; Jim used
an early 60's Gale Sea King 15 purchased for 100 dollars;
the same red and white Sea King shown in the duckworks
"Primer on old outboards" article. I had tried to buy
that engine but someone beat me to it, but I kept track
of it and it came back on the market. It has a lower
unit cracked from allowing water to freeze in it, and
then patched with epoxy. The engine runs well, with no
work being required to get it running. At 78 lbs ( according
to Jim's bathroom scale,) it is lighter than most modern
The 15 was plenty for Jim's AF4; my boat being about 200
to 225 lbs heavier, the late 50's 18 I ran was plenty
