This Kind has Transmissions too
Wooden canoes like this one will have at least forward and reverse "transmission" gears........
PS, wet or dry all you need is a flame arrestor for Marine use of the same carbuterors...and the trans is down there too if U look close

Boat transmissions
I assure you that boats can have transmissions. I had to rebuild one last year.
The transmission was basically an automatic with a clutch pack for forward and a band for reverse.
And there was no torque corverter. The flywheel was hard bolted to the trans input shaft.
here is a pic of the type of trans i rebuilt:

Let's see:
- you personally insulted two forum members
- threatened personal assault on one of the two
- don't know crap about mechanics
- won't admit you're dead wrong
- can't spell or construct a sentence
Where'd you say you were from? Oh, never mind- it's obvious

I guess I'll hijack my own thread........
I had a 1960 Mercury 100 hp outboard with no transmission. It was a 2 stroke and had 2 starters. One started the motor forward, one started the motor in reverse.
Back to the question. What are the pros and cons to a marine carb?
BTW ....Ironcross I like the dual quad hemi in the boat. Bet it stands right up.

The simplest definition for "transmission" is .... "a system of gears" . Every inboard/outboard drive system in the world has forward and reverse gears plus a way to select a neutral position for no drive at all. I think that qualifies as a transmission.

I can't think of any pros to a marine carb. Why not just get one that doesn't need to be adapted?
BTW- your bisexual outboard did have a transmission- even if it consisted of two gears forming an angled gear drive.

A true marine carb will have curved vent tubes for the bowls which will dump fuel into the carb in the event of a stuck float. This will flood and stall the engine rather than pouring gas all over the place and catching on fire. Probably a good idea for any type of vehicle.
You other guys keep mentioning the word "drive"... I wonder where that comes from...
I have an idea. Why don't you walk into your nearest marina and tell them you need the transmission for your inboard rebuilt? Then see how long it takes for them to stop laughing.

ZF is well known
Some drag boats even use the old power glides, but without the torque converter.
ZF Marine Transmissions ($300 million in annual sales) is a subsidiary of the ZF Group ($14 billion in annual sales). ZF Marine is now the largest supplier of marine transmissions, propellers, surface drives and controls in the world. In 1995 ZF purchased the Italian- based Hurth Marine Gear which continues to produce the smaller gears under the ZF name.
ZF Marine supplies a full line of single and two speed transmissions from ones used with twenty-seven horsepower engines all the way up to massive transmissions that can handle fourteen thousand horsepower. This variety allows ZF gears to be used in a variety of different applications and to offer replacements and alternatives to other manufacture’s transmissions

Is that brass colored tube at the rear of the engine, the old road draft tube?

I have a Holley marine carb with an electric choke I rebuilt for a ski boat I had a while back and it will bolt right up. My quadrajet is tired and not the correct carb anyway.
BTW The 58,59,60 Mercury Outboards had nothing you could technically call a transmission. The 90 degree shaft was called a "driveshaft" because the motor was a direct drive off of the crankshaft.

Swapped my worn out qjet for a holley marine spreadbore today. Here is what I found. Holley had an electric choke instead of the divorce choke that the rochester had. Holley has no high idle cam. (don't need it because I drive in warm weather only) Holley has only one extra "small" vacuum port. I capped it because I am running a vintage Accell dual point with mechanical advance and tach drive. Installed the carb and took out for a test drive. Throttle response and torque was incredible! Idle mixture took a few minutes with a vacuum gauge to set but now idles like a champ. Had to get a new brass fitting for the pcv out of the base, as the marine fitting was an 1/8 inch outlet. I swapped it for a 3/8 fitting from my hardware store. Car runs 100 percent better. Not as much back pressure or popping when letting up on the gas through the side pipe exhaust. No hesitation on acceleration. I know the rochester was probably in need of an overhaul, but overall the marine holley really fit the bill.

I used a marine carb for the center carb on my tripower. It has an electric choke, side inlet and correct flange to mount on the intake. It was 1/2" taller than my outboard carbs which was made up by the use of a 1/2" spacer on them. This also moved the linkage and fuel lines up to clear the nitrous lines and give more room for linkages. Fit the bill for me too!
