Sea Ray 240 Gas to Diesel Swap - Servicing and Starting 1.7L Mercruiser Diesel Preinstall
HTML-код
- Опубликовано: 5 авг 2024
- We bought this Sea Ray 240 with a 5.7 gas ( petrol ) and we are swapping it to a Mercrusier Isuzu 1.7L turbo diesel. There are several reasons. We are int he Philippines that is a developing nation and lacks infrastructure and services for this type of boating. It is literally 100 years behind much of the world when it comes to power boats and marinas for private use not commercial. Yes they have canoe type out rigger boats and those have been used for hundreds of years but not much in modern boating. If we have issues on the water there is no boat two company or boat service company to come tow you in or repair you on the water. The coast guard is limited as well so don't count on that either. We need reliability and diesel provides way more of that than gas does. Some of the common issues with gas engines in boats is ignition failures , sensors, fuel issues and dangerous leaks. This type of diesel is very basic in what makes it operate and eliminates so many points of possible failure. Next is safety of no explosive fuel as diesel does not have this issue. Lastly is fuel economy. This Mercruiser 1.7l turbo diesel which is now labeled as a Cummins diesel with current marketing of Mercruiser and Cummins gets 4 to 5x the fuel economy than the 5.7l gas engine. This is of great importance so It is cost effective and safer to transport diesel to the boat than gas. There is no marinas to pull into and fuel up. This means you will rely on cans and transporting it usually via tricycles.
There will be a small downside and that is a little less power. Not too much less and diesels have far more torque and this can be handled thru proper prop , pitch and gearing to put it real near the gas engine for top speed.

I have a friend who did a similar swap, he had a 24’ skipjack with a 5.7, swapped to the same 1.7 Cummins. I wen out off shore with him fishing, what a sweet boat that was, good cruise speed up on plane, got close to 7mpg as well. It did sit a little awkward due to the difference in engine weight, solved that by moving fuel tank aft.
So nice to hear this. This too is a 24' and 5.7. We figured the differences and I will be shaving about 400lbs off of it. I plan to offset with lithium solar batteries and a second fresh water wank. I do thank you for sharing your experience in a project almost the same.
@@TexasFilipino It ant gonna be fresh if you do that in it🤣
I don't know about you, but I am excited. lol...This is awesome to see it fire up. Can't wait to see everything together and you taking it out for its maiden voyage. Well it's not it's real maiden voyage but it is since it's rebuild. Loving this boat build series. Living the life brother. I love it. Hope to be there one day myself doing the same thing. Stay safe brother.
When you first moved the camera after the first start, you tipped it sideways and my reaction was "Shit, the motor has fallen over."
it bolted down
There are lots of good electrical shops in the city, surely they can rebuilt the old starter and. make if a spare for the sea ray, I remember the Canadian blogger Ben and his wife Ashley of sailing nahoa when they are Cebu they brought the old starter and have it repaired the electrician repaired it good as brand new.
I remember that episode also. I had my toyota starter done at one shop and it only lasted days so wont be going there
Nice job boss you found that "one for my son" weld
How exciting. I can't wait for this boat to get on the water
Gotta love the sound of a good runnin happy diesel engine. It’s one of my favorite sounds. Everyone thinks rolling coal is cool but I don’t. That’s actually bad for the engine. This thing sounds and looks like it’s happy and ready for work 👍
Now that it ran awhile and got bled out good it stopped smoking also. Just purrs. I let it run for about 30 minutes the other day.
@@TexasFilipino usually does take awhile to break them in and cold starts can be difficult sometimes but after they’re warmed up it’s smooth as butter. I could tell from the sound that it wanted to run and work again and you did a great job 👍
Great video! I like your DIY experience James. I'm nowhere near your knowledge level, but it's a joy to watch you figure things out. My first thought when you mentioned a "sandblaster" was "where is he going to get that"? Then you mentioned that you brought it with you! Given the tropical climate and rust issues, it would seem to be something high in demand out there!
Awesome...
Freaking awesome that it popped right off!
Sounds like a good runner for the sea Ray James.😊
If you take a long handle screwdriver and put it over each cylinder, one at a time and put your ear against the screwdriver you can listen to the engine for early signs ot trouble. 👍👍
That's awesome Great job.
Rightstuf gasket maker is what we use in the shop, works better than everything else that we have used over the years.
I love that right stuff!
Good Morning.... let's go.. Coffee
Sounds good
Want to get rid of rust forever use POR 15 .. bit you just overcoat if used in sunlight. Navy used to use on ships but .. of course now use a much much more expensive new process. POR 15 is brushable and it wicks into rust
And here I thought at the beginning when you said you wanted to repaint the pan, I automatically thought you would paint it with purple paint to make it look more exotic, purple bits are always more expensive. Yes, sir, she sounds like a runner. Are you ready to go water skiing yet behind your pump boat?
I had my kubota tractor starter and alternator both rebuild here in the philppines at a local shop for less than 3000 php for both. Just like new. A used starter alone was 22k Yep keep for spare
Very nice!
When a diesel engine breaks down, the engine doesn't stop running or its out of fuel
That motor purring like a female cat,,,,,almost ready for a trial run,great job
Your SEA RAY is going to sound funny 😂🙏🏼🙏🏼🇵🇭🇵🇭❤️❤️🤠
Hello my brother that little Diesel sounds good 👍 it fired right up like a champion.
Man thats gonna be a great choice for the power plant in that boat I wonder how fast it will plane out at ? QUESTIONS= what manf is that motor? Does Merc make thier own or is it a little Perkins or what ?? And did you fog the cylinders while it was in storage? Or is the injectors a little dirty (smoke) ??? Or did it get clearer as it ran just asking Po ?? Mabuhay Jame God bless yall 🙏
I sand blast everything, than use rustoleum paint ! Primer first
James why did you paint the inside of the oil pan
It was already painted. Please realize this is a saltwater boat. Salt gets in everything in all kinds of ways. A engine crankcase breathes and it will draw in salt mist over time and that salt will damage the metals especially something like that sheet metal pan I know your thinking is that oil is in it and no way it can rust but you would be highly wrong to think that. The previous damage to this pan was from the salt in fact and why it needed to repaired.
Use Jen Weld to seal that up.
Have you given up on the clog on the upstairs toilet????
Polygraph testing, rope and steel beam Midnight Express?
Coat the pan with epoxy, you probably shouldn't have painted the inside
I DID NOT PAINT THE INSIDE= everyone keeps saying that. It is coated from the factory inside - it is a marine salt engine I painted the lip
@@TexasFilipino my bad, it looked like the same fresh paint in the camera as on the outside that you painted. Seems weird that it's painted being that it is constantly covered in oil
You should not have painted the inside of the oil pan. The paint will disintegrate and plug up the filter.
The pan was already painted with marine paint from Mercruiser.

@@TexasFilipino I think you will find that mercruiser doesn’t paint the inside of the motors … I worked and played in the industry for over 60 years. The paint was probably applied by the last person who repaired the pan .
@@henrysangret5324 I did some research to find that it is coated from the factory. I also looked at a mercruiser replacement that too was coated. Thank you
@@TexasFilipino I only worked in gas not diesel .. must be a baked powdered coat, diesel I know softens paint and some powdered coat.
love your channel & have followed for years but as a safety tip please watch --blastone international on youtube . subject--( is silica sand safe to use as a blasting abrasive )
I used sand from the beach so for your knowledge also here is some information
"When we talk about silica exposure we are talking about crystalline silica or quartz. Construction workers could be exposed to silica when cutting, grinding, drilling, sanding, mixing, or demolishing materials containing silica.
The size of the airborne silica particles determines the amount of risk. Smaller particles can be inhaled deep into the lungs where they can cause damage. Larger particles, such as beach sand, are not as great a concern because they are too large to inhale."
