I/Os VS OutBoards
 

lets start with the good things about i/os


i/os get good gas milage, their easier to repair, they can be made very large, you can have more power in a v-20 if you have an i/o, easier to repair because you can use auto parts, dont need to flush them when your don runnin them, they dont stress your transom to hang them you dont need an expensive braket to hang them, and they draw less water than the outboards. But take up deck space and if you have a fire theres a fire on the boat you have to check and change oil. they are much heavier than an outboard.

now outboards

they have better tork than an i/o, if you have a fire they are not toatily on the boat, can be toatily raised out of the water, dont take up space on the boat, are lighter than an i/o, and they are eaiser to replace than an i/o. But they are horrable gas hogs even for strokes they are louder they pollute the earth more thatn i/os and there exposed to everything you can bang them on docks and hurt them.

Re: I/Os VS OutBoards
 

only thing that scares me about them is that seal that sometimes fails and lets water in lol...of course my overweight OB that sinks my scuppers aint no safer lol

Re: I/Os VS OutBoards
 

o/b's are also more expensive to replace.

Re: I/Os VS OutBoards
 

Auto parts are different from marine engine parts. Take for example the carb. Auto carbs when the float sticks and lets the fuel keep coming, dump the extra gas out side the carb while marine carbs dump it into the carb to flood out the engine and preventing a fire.

I was told this by a friend who paid TWICE as much to get the marine carb instead of an auto carb for his boat.

Re: I/Os VS OutBoards
 

i used to have an old 350 from a suburban in my v-20 an auto engine so i could use auto engine parts.

Re: I/Os VS OutBoards
 

According to SEA WORTHY magizine, I/Os are more likely to sink than O/Bs due to the boots that leak.

Re: I/Os VS OutBoards
 

Marine engines are built to run at higher RPMs since they don't have transmissions.

Re: I/Os VS OutBoards
 

hey fishbone, if you use an auto cam in your marine engine, the exhaust will suck water back in to the motor.

Re: I/Os VS OutBoards
 

There is another prime example of the many differences between marine and auto engines.

Re: I/Os VS OutBoards
 

she sure was fast though i could pass anything on the water. and my exaust was mouned on the transom above the water so she sounded like a muscle boat so i didnt need to worry about that.

Re: I/Os VS OutBoards
 

but i do admit it was a huge gas hog and i put the 470 in it and that through a rod and now i got this dinkey little 4 banger. :'( but next season when i buy a merc 350 with 280 hp WHOA look out fishbonejr on top agian with the fastest v20 on this site,

Re: I/Os VS OutBoards
 

My 90 O/B will push mine at 23mph at 4800. Dont think I could handle WOT. ;D ;D

Re: I/Os VS OutBoards
 

when i drive a 06 corvette to work every day and have a twin 250 outobard boat that can go 60 mph on the water according to gps you think i cant handle a wussy little 23 mph ;D ;D ;D ::) :P :P

Re: I/Os VS OutBoards
 

I dont drive a Vega like you so I will settle for a truck and 23.

Will get a larger motor when this one dies but hope not to soon.

Re: I/Os VS OutBoards
 

i would just have the vette but i need the truck for towin fishbonejr to and from the water.

Re: I/Os VS OutBoards
 

how long does it take you to get on plane with that little of outboard.

Re: I/Os VS OutBoards
 

depends on how hard I push it. Normally I'm not in any hurry so I ease it up. But when needed I can plane in about 10 to 20 seconds. Never timed it. Maybe next time out.

Re: I/Os VS OutBoards
 

ok i always run hard because thats how i drive. that must be why i go through so many engines in three years. in boats and cars.

Re: I/Os VS OutBoards
 

I cant afford engines nso I have to take care of what I got.

Just started eating a midnight snack. Please forgive the greasey fingers. ;D

Re: I/Os VS OutBoards
 

i cant eather but i do i just had to put a new engine in my mercedes benz that through a rod 3 days after the boat did so i am preety tight now becuase mb parts are like 4 time as expensive as american its an 1984 380sl so there ovesoly no warenty.

Re: I/Os VS OutBoards
 

Bendz look nice but never wanted one. They are German Arent they.

Re: I/Os VS OutBoards
 

yeah they are german. it was my first car and im very sentimental about my firsts so i have never sold it and never will just like my v-20 my first boat and as long as i am healty wealthy and wise they will always have my name on my title and sit in my driveway.

only car i have that is not from america.

Re: I/Os VS OutBoards
 

Germans make good cars.

I'm like you, This is my first boat and its a V20. Plan on keeping it for a while

Re: I/Os VS OutBoards
 

when they work but when they need repairs and this thing need repairs every time i make a left hand turn. it costs alot :o :o :o

Re: I/Os VS OutBoards
 

Turbinedoctor, except for the head gasket and freeze plugs, there are no differences between an automotive 350 Chevy and a marine 350. The newest of the new marine motors from GM have hardened exhaust valve seat inserts but are otherwise identical to their automotive crate motor equivalents. Most automotive motors come with brass freeze plugs, anyways.

The accessories are what make the difference. Marine carburetors have bent float bowl vents that dump the gas inside of the carb as stated earlier. All marine electronics are ignition protected. Marine distributors do not have vacuum advance. Marine ciruclating water pumps have stainless steel impellers and shafts. Marine fuel hose has a low permeability to fuel vapors.

Everything else is interchangeable between automotive and marine.

Re: I/Os VS OutBoards
 

I stand corrected on all except the carbs which was my first reply. Guess I should have stopped there.

Thanks.

Re: I/Os VS OutBoards
 

HA!!!

Re: I/Os VS OutBoards
 

Do you disagree with that??

Re: I/Os VS OutBoards
 

no i agree with that

Re: I/Os VS OutBoards
 

You cant hold it against me for repeating hear say can ya.

Re: I/Os VS OutBoards
 

beat me at my own game :-/

Re: I/Os VS OutBoards
 

you watch to much law and order.

Re: I/Os VS OutBoards
 

you really a lawyer

Re: I/Os VS OutBoards
 

just for tonite and part of tommarrow

but both my parents were lawyers and my grandpa was then he became a judge and my dad opend a business called TTC and sold it and has now been retired since he was 50 and my mom is still a lawyer to keep her self busy. so i get enough of it to know what the lingo is i will probable go to law school to

Re: I/Os VS OutBoards
 

just saw pictures of your boat and have one opinion and one question

my opinion is your throttle is backwards and my question is how hard was it to put that step ladder on the bow i need that for when i beach my boat.

Re: I/Os VS OutBoards
 

I wont hold that againist you.

Re: I/Os VS OutBoards
 

Throttle Backwards???? tell me more. It was like that when I got it.


The Bow ladder was easy. A couple of pieces of marine grade oak, recess the back so the plate will fit and the bolt through the deck with plates under neithe.

The ladder is bolted through the oak into a plate to spread the load. The plates under the deck spread the load down there.

Re: I/Os VS OutBoards
 

your binacle it is suposed to have the long part facinv ethe starboard side not the port side. did you buy the boat new?? or used.

thanks for theinfo on the ladder i am in the process of a semi over hall on the deck and dash so what 200 dollars more.

Re: I/Os VS OutBoards
 

Bought it used. Does it matter which way it faces since it works fine like it is.

Re: I/Os VS OutBoards
 

Could draw up a sketch of the mounting bracket for the ladder if you like.
