Is a car engine the same as a boat engine?
A car engine and a boat engine just about the same. You have to fit the engine with cooling system for the boat. one cooling system is using sea or fresh water to cool the engine (instead of radiator) Providing it’s the same block (not necessarily the same engine.
Can you convert an automobile motor to a marine engine?
Converting an automobile motor to a viable marine engine has been going on for years. Although, going back in memory, many of these conversions were disasters waiting to happen. Very early conversions simply amounted to lifting the motor with transmission from the car and slapping it in a boat.
Can you put a marinised engine in a boat?
It is very likely that the radiator will not have adequate flow placed on a boat. The environment is also different. Marinised engines take into account the corrosive environment and the motions experienced. Use of resistant materials and design choices make boat motors more resilient. Can you use a truck engine in a boat?
What happens when you run a boat engine in the ocean?
Consequently, the engines are running quite a bit colder than a car engine. If you’re running in the ocean and you get seawater above 180 degrees, it starts desalinating and you end up with a block full of salt and all the steam pockets.

Is a 350 boat motor the same as a 350 car motor?
The mechanicals are identical. Rust free head gasket and freeze plugs are used. GM uses a marine spec cam, but it is not very different from a stock cam. Both engines use stock single valve springs, and are not designed to run at high rpms constantly.
What is the difference between a truck engine and a marine engine?
An automotive engine kicks down to a lower rpm at top speeds. In contrast, a marine engine's sustained speed only increases with sustained rpm. Basically, a truck motor has four to six gears, and a marine motor has one. It only makes matters worse when a boat engine isn't properly broken in.
Can you engine swap a boat?
Your engine will need major repairs, or it will need to be rebuilt or replaced altogether. If you choose to replace your old engine with a new one, know this: There's a lot more to repowering a boat with a stern drive or an inboard than just swapping engines. Before you start, find out if the job is worth the money.
What is the difference between a marine engine and an automotive engine?
Marine Engines Are Heavy Duty A car engine typically only uses a portion of its horsepower to maintain a decent speed on the road. On the other hand, a marine engine is essentially at full throttle all the time just to move it through the water, so it has to be pretty heavy duty to keep up.
Are marine heads different than car heads?
86 to 95 engines marine and tuned port injection heads are the same. Most 87 to 95 model car and truck engines were throttle body with heads designed for low RPM that would rob you of power on your marine engine.
Can I put a truck motor in a boat?
The automobile engine, as used in passenger cars and a large percentage of trucks, is not adapted to use in motor boats. It is not built substantially enough for this, inasmuch as the power output of the motor-boat engine, except during starting or landing, is always 100 per cent.
Does Ford still make marine engines?
Ford engines have become more recognizable over the years and even sought out by informed buyers. In addition to their well-known car and truck engines, Ford has their hand in manufacturing boat / marine engines. And Ford has come to garner a reputation of being both dependable and strong in the marine market.
Did Ford make a marine engine?
Ford Motor Company will re-enter the marine market in an agreement with Indmar Marine Engines, the world's largest privately held manufacturer of gasoline inboard marine engines. Ford and Indmar Marine Engines made the announcement today at the Specialty Equipment Market Association premier event – the 2013 SEMA show.
How much does it cost to take an engine out of a boat?
So if you are one of these lucky ones, your engine replacement will cost around $5,000 if you either want something smaller or get a good deal. $10,000 is the top of the range estimate you will have to pay in case you are looking for more power, and/or fancy one of the bigger manufacturer brands.
How much does it cost to install a new motor on a boat?
An inboard powerboat engine replacement costs approximately $15,000, while you should set aside about $5,000 to $10,000 to replace the motor for a sailboat. If you have a sailboat with an outboard motor, you will pay significantly less, somewhere around $1,500, because this vessel uses wind as the first power source.
Are outboard motors better than inboard?
Inboard motors generally last longer than their outboard counterparts. You can squeeze roughly 1,500 hours out of an inboard before necessary maintenance. Outboards, on the other hand, last about 750 hours on average. So, the inboard option means less maintenance (nearly half) even though they cost more initially.
Can I use a truck engine in a boat?
The automobile engine, as used in passenger cars and a large percentage of trucks, is not adapted to use in motor boats. It is not built substantially enough for this, inasmuch as the power output of the motor-boat engine, except during starting or landing, is always 100 per cent.
What is the difference between marine diesel engine and regular diesel engine?
Diesel engines are all fuel injected and are designed for ignition using compression. Automotive gasoline marine engines that use a carburetor have a strengthened body to prevent fires.
Can you put a car thermostat in a boat?
If it uses antifreeze (closed cooling system), use an automotive thermostat which is the correct opening temperature. If you have a raw water cooled engine, go with the marine thermostat. The materials may be different (stainless vs plated steel spring, etc) to withstand corrosive effects of salt or fresh water.
Is there a difference between marine gas and regular gas?
Re: Auto Vs Marine Gasoline The difference is about 4% better performance and economy in the marina gas due to 4% more BTU's in the ethanol free gasoline. Price is about 19 cents more per gallon at the marina.

basicaly im sick of the outboard it has problems starting all the F^^* time and it doesnt pull fast I work in a auto shop so I got this idea [drawn pic] and i kno you ppl said that marine engine can ceep high RPM level for a long time and it might be a problem for cars engine to be redlining all the time so dats why Im going to install [ FIG 1 ] so i wont need to rev it and to cool im going to ceep the radiator and rad fan any ideas? feel free to post drawings oh and the brown things lol engine mounts I was too lazy to draw.

The biggest issue is marinising the engine against spark threat. Start with the alternater and work your way through the rest of the alphabet.

The way it's drawn, the prop will turn twice as fast as the engine. I'd reverse those pulleys.

A new outboard would be easier and cheaper. You also need to add a thrust bearing, cutlass bearing, strut and gear box. The hull has to be modified structurally. Also the CG may change enough to make the boat handle badly.

You really just need to buy a new outboard motor. Yours sounds totally worn out.

For sure, the risk of death by explosion is the real key to why car engines don't go in boats.
What are the differences between marine engines?
Marine engine builders are quick to point out that there are key differences in building a marine engine, including valve-seat design and width, valve materials, fuel delivery, engine operating temperatures, and internal clearances.
What happens when you run an engine in the ocean?
If you’re running in the ocean and you get seawater above 180 degrees, it starts desalinating and you end up with a block full of salt and all the ste am pockets. They tend to run these engines a lot colder, so the cylinder clearances have to compensate for that, and so do all the other clearances.
Why is the engine controller important?
It not only improves driveability, but also gives the manufacturers a greater measure of control over engine parameters. If temperatures spike or oil pressure plummets, the engine controller can limit engine output so a boater can limp home rather than be stranded.
Where is Ilmor Marine?
Ilmor Marine, an engineering company in Plymouth, Mich. , has successfully “marinized” the aluminum V-10 lifted from the Dodge Viper. Ilmor engineers were able to divorce themselves from their automotive mentality to create an engine that withstands the duty cycle of a high-performance boat.
Is it important to recognize the differences between car and boat applications?
It’s important to recognize the differences between car and boat applications. Once you understand the differences, you can separate the good deals from the bad. Editor’s Note: This article originally published in February 2016 and was updated in December 2017.
Is a marine engine colder than a car engine?
Most marine engines take their cooling water straight out of the medium they’re running in. Consequently, the engines are running quite a bit colder than a car engine.
Can you shift a marine transmission forward to reverse?
It can and has been done, but, with older transmissions and internal changes. Such a transmission will be considerably longer than a marine gear and it won’t take the forward and reverse thrust. Shifting from forward to reverse as a brake may create excessive wear on the auto transmission.
Is a small block Chevy still used today?
A prime example is the so-called small block Chevy, first used in autos in the late fifties and still in use today. No, it’s hardly the same motor, but the basic block pattern for major bolt-on appendages has remained essentially the same.
Can you convert an automobile motor to marine power?
Today there are conversion parts for popular automobile motors to make them viable marine power plants. But that doesn’t mean that any motor can be taken from an auto and converted for marine use. Conversion parts must be sold in quantity to make a profit.
Can you use marine appendages on an engine block?
Marine motor manufacturers have used some, but individual parts are not available. It is possible to buy the manufacturers marine appendages and put them on a basic automotive engine block, but the cost would be prohibitive.
What is a marine engine?
Marine engines are designed to run fast, with a huge load, for long periods of time. Sounds like a winning combination in my book. Marine engines also cost a lot more, if I remember correctly. Research it some, and I'm sure you'll find all the info you need.
Which way does a port engine turn?
The port engine turns clockwise,the starboard engine turns counterclockwise.A single engine turns clockwise.A boat motor is high torque.It would have to be recammed and/or changed as to rotation.They will not interchange without work.Now who knows why it is called portside,and why.
Do boat engines work?
Yes it will work , boat engines are build a little looser then car motors on the specs so they can actually work at 5200 + RPM over a piriod of time since boats do not use a tranny. other then that its the same..if its a HP boat engine, u will have better exhaust valves and stuff too.
