Outboard vs Sterndrive [ Inboard Outboard vs outboard ] Which is Best? why? Inboard vs outboard

[@trikebum5]

My sterndrive has a chevy engine. Parts are insanely CHEAP compared to an outboard. I can buy a rebuilt chevy straight six for $800. Try that with an outboard Mercury! With the intercooler I don't worry about winterization. Also, my 20' boat is trailered so much of the post just doesn't apply to normal recreational boats. I do admit, overall, an outboard may have a slight advantage for a major breakdown.

[@ballhawk387]

Stern drive craps out and the boat is out of commission until it is repaired, or swapped out. Outboard goes out, and it can be swapped out within a few minutes if one has a running backup outboard on hand, as I do, *if* the boat is not *too* big for a cheap smallish outboard. That decides it for me. Though it may take an engine crane or hoist to quickly swap out a larger outboard without help. Mine are 20hp or less, and easy enough to swap without assistance, and none cost very much. If I had way more horses and a much bigger boat, I might think differently for that rig, though I'd always have a small enough boat that a 20hp or less backup outboard would do on hand to have something I can get out on the water without waiting for a repair.

[@ThatGuyFromDK]

Don't have to scrap a boat, all engines can be changed. Just takes more time

[@ballhawk387]

@@ThatGuyFromDK Until the stern drive is repaired or swapped out, yes, good point. Seems it would be much, much more difficult to swap out a stern drive, unless it's a very big boat that would require a heavy outboard, but I'm not so familiar with stern drives.

[@duncandmcgrath6290]

Mercruiser for example made millions of stern drives , these can be swapped out faster (or overhauled) faster than any outboard of equivalent horsepower. Power/ $ ratio of a stern drive will always be more economical

[@ballhawk387]

@@duncandmcgrath6290 Faster than loosening a couple clamps, lifting off the non-running outboard, putting on the running backup, and tightening its clamps, which typically takes a few minutes?

[@ballhawk387]

@@dudeski5333 Of course this depends on the rig. I intend to always have a small boat with a low hp outboard on hand, regardless of my main rig, so I always have a rig I can use to fish. Beyond about 20hp, those extra horses bring greatly diminishing speed returns, practically speaking.

[@Chas1160]

In my opinion, outboards are better all around. I have a Bravo II outdrive with a Mercury 454 large block . This engine is fast but burns 20 gallons per hour at 3200-3400 rpm with 50% fuel tank and 2-4 people onboard. If you don’t have a boat lift and/or trailer, you must be very diligent to maintain the outdrive. Saltwater can be hard on outdrive without proper maintenance. I have a diver that cleans the bottom and outdrive every quarter. The outdrive and bottom is thoroughly cleaned and painted every two years as a minimum . If you don’t have the resources for proper maintenance, don’t buy an outdrive and leave it in salt water. The boat is very attractive, has a nice swim platform. Warnings: keep up with the maintenance OR you will pay thousand in repairs. Boat mechanics are $100 plus per hour as a minimum. My future plans is to either get a boat lift OR go with a straight drive, or outboard. My boat is too big to trailer myself.😊

[@AquaMarine1000]

In the long term, diesel outdrives will be more reliable and last longer, thus being more cost-effective over the life of the boat. Also, in the event of a fuel leak, diesel won't easily catch fire or explode. Contrary what has been stated, some sterndrives can be tilted clear of the water.

[@charliegglines3965]

I’ve got a 26 Bertram with 2 alpha one gen 1 drives. If you don’t know how to work on them or hire the wrong guy to work on it, it’s a damn nightmare for you. However, it’s a tank and they’re faster than inboards. And if you hit a rock you won’t lose the whole outboard. If you learn how to work on them by the books they’re really not terrible. Be diligent about about the time periods of water pump, bellows, and shaft seal services. I would definitely recommend getting a counter-rotating lower unit if you have 2, docking can be a pain in the ass.

[@highlandmalt6368]

Great balanced video. You missed one thing - if you need the resilience, longevity and reliability of a diesel, you have to go sterndrive.

[@hayatel2557]

For the moment I see diesel outboard is a good game changer

[@hugoglenn9741]

Way too expensive

[@bugsternc]

One thing however, when you make the conversion, for an identical speed on the same boat, you can mount an outboard motor less powerful than its inboard counterpart, as a result the consumption decreases as well as the final total weight of the boat

[@ChrisG9978]

Stern drives still seem to achieve more speed with lower horsepower ratings. However, stern drives are more difficult to maintain, especially for winterization. Outboards are easily drained for winter storage. Stern drives also protrude down farther below the boat and don't provide as much clearance when raised...much easier to beach a boat with an outboard and safely keep the lower unit on an outboard away from harm when in shallow water or when beached.

[@duncandmcgrath6290]

Negative, prop center line is the same on I/O and outboard.

[@richmac918]

There was a time when stern drives and outboards, when their pro's and con's were compared, were pretty much on par with each other. Outboards were 2 strokes, didn't have the longevity of a 4 stroke stern drive, were noisy, and smokey but today those issues no longer exist. Just about the only advantage a stern drive has now is that it is cleaner looking and you can get a better swim platform. Other than that, outboards win just about all other comparisions hands down.

[@Black.Sail.Plumbing]

Sterndrive/inboards are not for the weak and oublards are not for the cheap. One of my restored boats (19' Seaswirl Sierra Cuddy) is a sterndrive and it is such a great handling boat. Its a 4cyl chevy and is cheap and easy to work on, gets on plane smoothly and has a pretty decent top speed. I love it just as much as my Seaswirl Striper 2101 with a 200 Honda outboard, difference is the Honda outboard cost $20k which is more than the purchase, restoration and repower cost of my sterndrive boat. Pros and cons of both. Just get what you can afford to repair because you will need money more than anything!

[@hugoglenn9741]

I don’t know how you are buying your motors but in 2004 I bought a new holdover previous year 200hp Honda for $8600 with begining of the year rebate. Prices have gone up but I can probably deal on one for $15k or a little more. If not I can find used ones for $10k or less.

[@joshawageorge2122]

I would go with the inboard/outboard mercruiser because there's the option of switching out the gear ratios for better performance and fuel efficiency.the outboards are limited to just changing the prop for a difference in the rpms and fuel economy.all are susceptible to power to weight ratios for performances

[@kw57rx8dr.9]

Two big problems I have with his conclusions are, one, that the main reason for his outboard preference assumes that you don't pull your boat out of the water after every use as so many I know do or even when the bottom needs cleaning if it's water bound. Second if you have multiple outboards you are not saving any money on any part..

[@dugnology]

for small pleasure boats, outboards today are leaps better than even 10 years ago. The problem with stern drives is the number of critical failure modes. We have muskrats on our lake, and they like to chew rubber. Not an issue with an outboard. With a stern-drive, there are multiple bellows that are just waiting to be chewed up. Your boat will sink. There is also the added complexity of the tilt mechanisms.

[@marcseclecticstuff9497]

If your bilge pump is working, the boat won't sink, not that much water comes into the boat. I had my bellows fail on in the middle of a 2 week trip last year. It was a non-issue, the bilge was only kicking in once maybe twice an hour. The only bellows that matters is the driveshaft up on top and pretty difficult for a critter to get to. If you leave the drive down, there's no way for them to get to it, it's blocked by the drive. I've always had I/O's, both Volvo and Mercruisers, and always done all the repairs myself as they aren't difficult. One advantage of I/O's not mentioned here is parts are a lot less expensive since many are common car parts. Sure, there's a few that are marine specific like the starters & alternators, but if you break down in the middle of a trip, you can just run to the local auto parts store and get what you need to get back home. They won't have anything for an outboard. If you are in a high crime area, an outboard is relatively easy to steal, on an I/O they'll only get the relatively inexpensive drive. Like everything in life, there's no right answer, everything has it's advantages and disadvantages.

[@wickedleeloopy2115]

If you want the torque & fuel efficiency of a diesel , go for a stern drive , otherwise just free up space & use an outboard

[@KiteKrazKev]

Amazing video I built a 22ft hiliner center console my dad had a engine laying around at his boat yard so I kept it original with a io and I wish I went with a outboard reason being is deck room aboard boat and be able to boat in shallow water

[@gabbermaikel]

i find it funny how he said the better power to weight of the outboard allows for better top speed of the outboard. Then we go to fuel consumption, and we see the inboard actually is a decent amount faster at prettymuch every rpm and uses less fuel in the process. That small of a weight difference in the size of boat the 300hp motors go on wont make much if any difference. But the position of that weight makes a HUGE difference. Also dont compare a 300hp diesel to a 300hp petrol/gas engine. That 300hp volvo d4 wil be WAY stronger then all those 300hp engines it was compared to. The torque on that diesel wil make it so much stronger that its more likely going to be competing with a 400hp outboard. And at that point we are comparing it with a mercury wich costs i think 56.000 in the usa? So the price difference all of a sudden isnt big at all.

[@hugoglenn9741]

Wrong, seen many carbed sterndrives that guzzled gas. All larger HP outboards are fuel injected, much more efficient

[@jenniferstewarts4851]

on "larger boats", in the 32-47' territory, inboards are often accessible from below decks as well as on deck. for example the Nodric 42 engine room is fairly open. people often use it for extra storage space too... but the key and catch is. if its bad weather out. storming, ice, hail, and you lose an engine, the ability to drop below decks, and work on it there, do maintenance in a safe and secure environment rather then hanging off the bow in and ice storm... is always a plus.

I personally though operated a 28' cabin cruiser and boy did that thing EVER get tossed in bad weather. but compared to other boats it fared much better then the smaller ones. and yep it was an inboard the motor though was accessed through aft deck, but the aft deck was covered and enclosed... so we could work on it safely away from the elements.

For a fishing boat you definitely don’t want a stern drive if it’s not offshore fishing. There’s just no arguing that you aren’t happy crawling around in a few feet of water with a stern drive. You simply can’t pull it up enough to avoid damage while you can with an outboard. An outboard if left unlocked will ride up and over if you touch bottom. Sterndrive ain’t goin nowhere .

Went to the Coast Guard station later and talking to the instructor of the boarding class. On my way home I got a call from the commander of the station to apologize. I’m in the aviation business and the Coast Guard was conducting boarding training using a checklist. The aviation business doesn’t stand for such incompetence.

OBs all routine maintenance can be done standing next to the engine or small stepladder by anyone with limited mechanical abilities including oil and gear case fluid changes, OB winterization involves trimming the engine down and letting gravity run out the water (although I do the oil and gear case changes too) no paying a mechanic to contort under an engine hatch. OBs can be trimmed up above the boats keel and still maintain steering without stressing the driveline like an IO. OBs have NO bellows (to leak and sink your boat) or gimbal housing to be replaced every couple years. All modern boat manufacturers have retooled their molds to include extended swim platforms that are as big if not bigger than the IO boats.

That's if you're too cheap to buy a closed loop fresh water cooling system. And manifolds generally need to be replaced every 5-10 years anyway. Probably less if you have a fresh water system. Also you can negate this by just flushing with fresh water after you get done riding in salt.

I/Os are garbage especially on saltwater . There's always salt water in the bilge with near 100% humidity causing corrosion on the engine, cables, outdrive etc.. All your fuel savings (GPH) go out the window when you start replacing corroded starters, alternators, cables etc.. Gas outdrives are more likely to blow up from gas fumes in the bilge also. I've seen in numerous times on the Jersey shore. Get an outboard!

Outboards get stolen easier too.

[@Tracker7266]

Outboard.... all day long.

[@johnboy5167]

Wouldn't even consider an inboard it's outboard for me

[@bomguy999999]

OK, WTF is a "Veradoo"?

[@grimreefer5159]

Outboard is a an easy win. No real benefit to to a stern drive.

Outboard might be more usefull but such a big thing at the back looks ugly if u ask me
