Default Engine and Tranny into a boat?

Just got a 21' 73 sportcraft boat. Have a recked an 80 camaro w/ a good
267 (v8) and tranny. The boat is pretty rough and has a 165hp
mercruiser. I'm wondering for the pain in the ass of getting it
running with water under it and so-on maybe I could just put the prop
onto the drive-shaft of the 267 and figure a mount. the only issues I
can think of are the seal arround the shaft, and the ratio. Anyone know
a mercruiser's ratio? How bout the ratio of a 267 V8 to the drive-shaf
for the 80 camaro? I figure the tranny would be really cool for
choosing fast or pulling a skier.
Thanks,
Elliott

Just shorten the driveline and weld it up to the outdrive coupling!!!

Then stomp the gas pedal (make sure you install that also) and away you go!
Way cool dude!








PS Make sure you go out alone. I would not any innocent folks to die due to
your stupidity.

This sounds reasonable... Hoping the outdrive is OK on the new boat.
Seems others are fearful of cooling... Well a radiator works on a car in
traffic - and I'm sure it would work on a boat too.
I was thinking I could mount it behind the boat with an electric fan (like
hot-rods use). Once I get the bugs out I may turn this $500 boat into a $20K
boat and one that runs reliably. I would think that the 3 speeds of a real
transmission would be a big advantage. I also think I can use the power
steering pump and break master-cyllendar for trimming/steering/etc. The best
part is the great performance with dirt-cheep parts. Still it's tempting just
to get the ol mercruiser running - maybe I should put that into the camaro
(haha).

Elliot,

Commercial fishermen did ( and some probably still do) that for
decades, mostly with old heavy 6 cyl. truck engines. It is an
interesting thing to play with. Don't know if a Camero is a good choise
or not. I hear you can build a hell of a boat out of a '51 Chevy
pickup.

The Mercruiser is probably a better bet for normal use.

I think you are going to run into all sorts of performance problems.
My Bravo II has a 2.0 ratio on a 22 x 22 prop @ 4000 rpm = 2000 prop
turns. I think if you run a light crankshaft as is in the automotive
engine you will;

A. Never get the prop turns right.
B. Burn out the main bearings due to overload.
C. Have an engine and trans that overheats all the time.
D. Waste a car load of money on the shaft engineering.
E. Probably blow yourself and any passengers to kingdom come, because
auto parts do not meet USCG marine safety requirements.

Please! for your own safety, become conversant with United States Coast
Guard Marine Safety requirements and SAE standards for: Starters,
Carburetors, Flame Arrestors, Alternators, Fuel Pumps and Ignition Systems.

I like that idea!... I could weld barrels onto the axils and put paddles on
them. That way I could just change the wheels and drive on in. On the front I
could either run a chain to spin them from the rear or use them to stear. Now
that I think on it more heck I've alwayse dreamed obout building a car-boater
thing. That is drive up to the water (maybe pulling it on a trailor) put the
boat in the water and drive onto it. strap on and use the car's wheels to drive
a wheel rigged onto a prop. Could use a car-differential in reverse tied to a
prop. That way even reverse would work, And whatever the gearing a
chain-sprocket mechanism could adapt it. hmmm why arent these things for
sale??? Hasent such a thing been done? Just saw the wheel-drive-on cyllendars
used at the motor-vehicle-immisions testing system. Seemed they worked pretty
well.

I suggest contacting those Cubans that almost made it to the USA
recently in a 53'Chevy truck. Do what they did and it would save lots
of time as you could leave the driveline in the Camaro. Just hook the
prop to the driveshaft the way the Cubans did and strap barrels to the
side. It will be much safer and you will have two boats. The US Coast
Guard had to sink the Cuban vessel and it was not that easy.

Despite the critics I think it would be semi-cool. Just think of James bond
when they had what looked like a 350 on a little 'asian' canoe-type-thing. I
would review Junkyard Wars episodes for ideas. Or I would put a nice engine
on a 21 and put the camaro engine in a 10' flat bottom and make the ppl at
the watering hole fear your wrath.

"in all seriousness" I always thought an engine and a tranny in a boat would
be cool, but a 21' is a big boat. Get a big bass boat or something that is
cheap/common and make a sleeper.

Differential brakes on the paddle wheels would allow "power
steering". I saw it done on a built up fishing scow. One brake
pedal for each wheel. No rudder, I think. Not with floating
barrel wheels, or drive on, it was just a side paddle wheeler
using a car differential. It made a lovely duck blind, with full
heat.

The chevvy engine might not like half a ton of thrust pushing on
the end of the crankshaft. Nor will the tranny tailshaft. A
thrust bearing is required, or a side paddle wheel rig. A
stuffing box would surround the prop shaft with a packing gland
compressed between the inboard end fitting nuts.
