Motor for a 12ft Tinny

Hi,
   (WARNING: Boating-related post!)

   Thinking of getting a Cheap & Nasty "tinny" (12ft rivited-aluminum
cartopper) instead of building the garvey (no indication of when there
will be room to build ANYTHING in the new workshop!).

   I want to power it with a 9.9hp 4-stroke. Sound like a good match? (It
has to be 4-stroke - my Lady refuses to ride in a boat spewing 2-stroke
smoke). Should it be long-shaft or short-shaft? If it "should" be short,
how bad would a long-shaft be? Lots of used 9.9hp Honda long-shafts in
the Buy'n'Sell.

Go for at least a 13' and 14' is better.  Weight difference between the 2 is
about 12# and the carrying capacity is about 125-150# more.  Some alum boats
require a long shaft and others need the short shaft.  If the transom dips
down from the sides, requires a short shaft, if is straight across the top
most likely requires a longshaft.  Putting a longshft on a shortshaft boat,
will lead to a broken transom and the bow either rising all the time or
plowing (forget which, I think it is bow rise).

I have a old 14 ft aluminum fishing boat with a 71 7.5 merc on it. The 
7.5 pushes it along just fine with me the wife and the two kids. I am 
sure a 9.9 would do nicely for a little fishing as well..

Yeah, and a 16 is just a bit heavier, and an 18 would handle waves
better...been there, done that. 12ft is what I want - there's just the
two of us (probably mostly just me!), in calm water, often in a lake with
no boat-launch. Those 12 lb get heavy when you're hauling the boat up a
gravel bank by yourself!

   While I doubt the 4" difference would break a transom, I can see it
would stress it more, and result in bow-rise.

Sounds like an interesting boat. My oldest and his friend are out 
fishing regularly on a 10' micro plastic bass boat, which they putter 
around with a 2hp. They were rather surprised by the difference using my 
4hp made.

As for the short-shaft... when I was part of a student yacht club they 
were always buying old motors and swapping in/out lower units. I think 
they have the record in Seattle regions on number of motors ruined in a 
given season. But the point is, there were always extra short shafts 
lying about. Ask around at places which do lessons and other work with 
small motors if all you can find is a long-shaft. I'm sure you can find 
something.

I went with the 14' on my Valco.  The extra room is really nice.  Get a set
of wheels for the boat.  Eide Industries makes the nicest.  I have
wheel-a-way where you have to pull a pin to flip the wheels up and down.
The Eide, have a spring loader pin.  Flip the wheels down and roll the boat
into the water. then reach over and flip them up.  If car topping, flip the
boat over and and ahve the wheels rolling when you lift the front and start
it onto the car rack.  Then go to the transom and pick it up and slide on to
the roff the rest of the way.

LLoyd, the highth of the Transom on most 12ft's is under 15" which calls 
for a short shaft. I have known a few guys who tried to go with a 
longshaft because that was available cheaply .. they found handling to be 
a problem and they certainly had well 'polished' skegs from ticking rocks 
and logs in the rivers around here. Most of them get a shortshaft after 
the first season. Most of the 12fts that I have seen are only rated for 
7.5HP, but then most of those are older tin cans .. they don't wear out 
real quick. 

That said my younger brother used to run a brand new 20 Merc (shortshaft) 
on an old 13ft Crestliner with a reenforced transom. And while it went 
like a bat out of hell it was scary to handle at anything approaching 
full throttle .. so scary that he upgraded the boat to a much heavier 
14ft Princecraft after a couple of seasons .. That Crestliner was fun 
though .. sure would go airborne jumping beaver dams coming down stream  
from his bushcamp <large whahoooooo and splashdown>

I use a little 12ft Sylvan for  waters that are difficult to access, 
weighs a whole 98lb which makes packing it down over steep banks, over 
alder brush, etc a breeze. It handles my 210Lb, my wifes 120Lb and her 
dawg 17Lb plus tackle quite handily and with a 1983 Evenrude 7.5HP moves 
along quite well. With just me in it and a 5 gallon pail of water in the 
bow it really skoots.
