The music killed this. let's hear the engine.

[@EndlessDan]

Love it! Have been thinking about this swap for a few years! Im getting close to start getting parts to so a twin set up on a 31ft boat...

[@bornpompey2]

I am currently converting my 24ft fourwinns liberator, the 8.2ltr big block was junk and I am building an om606. I have made the conversion plate to fit the OMC bell housing, the flywheel is made and I am hakfway through the watercooled exhaust 🙂

[@KacperR7]

Sounds good! If you follow the OM606 Superturbo FB page, don't be shy to update, there is a lot of people with knowledge and experience with these engines

[@alexanderonderwater6059]

Hi, we have watercooled exhaust manifolds complete with watercooled turbo available for the Om606. Billet anti corrosion aluminium.

I have been thinking of this exact same style swap setup and I'm glad to see it work out so well! I bet this engine would run great for a big heavy cabin cruiser like that and mileage would prolly double if not more than that!!!! Awesome to see you guys get it done and very clean looking! Keep up the good work guys and thank you for the inspiration!!!!!

The Best video with Disel engine Swap for Boat…Make please more video with this boat…top speed, fuel consumption other work you did…thank you

[@KacperR7]

Thank you, I will make sure to do an update this summer!

[@jamesv2811]

​@@KacperR7This would be great, please do it. Can you give us some quick numbers?

[@Mr_Ivar.]

That's one tidy job, @KacperR7. Like it. My 1990 Maxum 2100 is getting OM648 3.2L engine fitted.

[@ferrarihelp1]

Yes. Please. Some real numbers. Like fuel consumption what rpm cruising. What size prop. Etc. i have an 2001 OM 613 CDI straight 6 cyl. Same as the 606 but with common rail. I found and bought a stand alone ECU in Europe. Made for this particular engine . Its a plug and play setup. Uses the factory engine harness. I can tune it upwards of 350hp.wirh the stock engine internals. The idea is to put it in a boat and get rid of that big boat anchor 1185 lbs Mercruiser vs 585 lbs OM613. Thanks.

[@Mr_Ivar.]

@@ferrarihelp1 can you drap the link of that ECU, please !

[@Sebastian-Pereiro.]

шикарный проект получился👍

[@adamsyclone7409]

Wow great design one thing I’d do abit different is have the exhaust coming out of the turbo point up and then drop down and have the water mix at the bottom of the dip almost all marine diesel do something similar to stop water from back flowing into your exhaust turbo or cylinder but regardless sweet build tho love the boat

[@MrInsanityflea]

Nice! Most guys here just put in the Volvo Penta diesel with it's outdrive and everything. Most common is the D4, 3.7 litre 4 cylinder, Starts at 150hp and goes all the way up to 320hp. Super light on diesel. The 5.5 litre 6 cylinder can do 480hp.

[@tonydiesel3444]

In usa?

[@blackjackfabrication4043]

The OM606 can do more that 480 and it is only 3.0L

Excellent job. Love your video

[@KacperR7]

Thank you

[@The0rmg0]

what's the reason for the watercoold exhaust manifold? dosen't it reduce turbo efficiency?

[@mawa9843]

I was thinking the same thing. I'm genuinely curious for the reasoning behind it.

[@The0rmg0]

@@mawa9843 i did some research. its for keeping engine room temperature under control. Because Boats haven't a lot of airflow there

[@mawa9843]

@@The0rmg0 Ok, that makes sense. From the video it seems to flow quite a lot of water through the manifold. Maybe you can get away with less cooling and gain some turbo efficency while doing so 👍

[@KacperR7]

@@The0rmg0 That is correct, high engine room temp is a big hazard. There is little to no natural airflow in the engine room. We have added two high flowing fans to reduce the heat even more!

Quel bonheur de voir ce genre de videos faites par des français, vraiment. Je suis suisse, je vous souhaite le meilleur. Ne le mettez jamais a fond, le moteur n'est pas fair pour. ne depassez jamais 2900 tours en croisière avec le om606 et vous n'aurez jamais de problèmes. Comment avez vous resolu le familiarisation avec la boite de vitesse? fabrication artisanale ou déjà un kit CNC par internet?

Well done mate! my om 606 is still waiting in a garage to be fitted in the boat :(

[@silencer2001]

fantastic work. I'm converting my boat to an om648. Everything is working so far, but I don't know how to solve the problem with the ignition breaker for reverse gear.

[@KacperR7]

For now we don’t do anything, and with the low idle it’s not that big of a ”clunk” when switching gears

[@KacperR7]

But someone suggested to wire up the original MerCruiser ignition switch to the solenoid for shutting off engine, to give it a short signal to “cut engine”

[@HerraPlagu]

I got bmw m57 with alpha 1 no problems changing gear without the shift interrupt switch

[@oliverf944]

Epic! im building a 9m boat and considering the 606 with stern leg too. Did you use the mercruiser raw pump too?

[@F14foreverF14]

OM-606 Diesels are legendary, especially when fitted to burn-out 🔥 monsters like W-201 190-D or W-124...and now on a boat...epic. Can your 606 boat do burnouts? 🤣 Am sure the water cooled charge air intercooler will provide denser air = more boost = more power baby!

[@leo-stief]

Hey man, sick video and great conversion! 😍 I‘m thinking off a similar conversion to a sea ray srv 220 cc. Did you encounter any issues with the stern drive? My potential boat has a alpha one gen 1, thus I’m a bit afraid of braiking it with the om606‘s tourqe? And how much money did you spend on the cooling? I’m not sure if I should go for an water cooled exhaust manifold including a heat exchanger or if I should get a separate exchanger or both. Best, Leo :)

[@przemaj3425]

how much oil does it consume and what engine does it come from?

[@guido0582]

Great video. I've been tossing up something very similar... is the engine stock internally or has it been rebuilt?? Those Mercury V8's are reliable but very lazy in terms of power. Once again great job

[@KacperR7]

Thank you Engine is fully stock internally, that's also another reason we aren't pushing it past 300hp. As it would put way too much unnecessary stress, on the engine and outdrive. They are known to be pretty reliable around 450hp in cars, but being in a boat with full load all the time, I don't think it would last.

[@guido0582]

@KacperR7 it's quite the opposite. Diesels are designed to "work' under load so being in a boat under constant load is perfect. Great job

[@maximilianeissner4759]

@@KacperR7 In industrial applications diesels are often running at full tilt 24/7. Because you have less rpm variations, the stress, wear and tear is less. But it is smart to not push it too much, which does not seem to be neccessary anyway.

[@JayHughart]

Can you make and sell me all the parts??? I am pulling out a 606 this week that has a bent rod gonna build it and do this!

[@Puzkajuzzi]

Beautiful work🤩 I am dreaming of taking on a similiar project one day. As you are using alpha are you shutting off the engine before you shift it in gear and then start the engine in gear? Here on KZbin you can see another OM606 marine engine from Jari Kåhlman who implemented a system to make the engine shut off for a split second during shifting in order to protect the outdrive. To my understanding similiar system is implemented from factory to mercruiser engine + alpha outdrive systems which is called mercruiser shift switch. Bravos don't have this feature from factory as they are more sturdy. In case you knew all this and shift the alpha when engine is running, you are not worried about it breaking or you don't think it will break?

[@KacperR7]

Thank you! Currently not doing anything to prevent damage while shifting into gear. As the idle rpm's are fairly low, it doesn't give that big of a "clunk" when shifting into gear, feels similar to when the merc engine was in. But certainly something we thought about! The mercruiser switch could be implemented, onto the solenoid that is used for switching off the engine, just running the signal for a split second to further drop RPM, and we might play around with that this summer!

[@baronasstudiotm6958]

[@mattihyvonen2568]

If you run the engine for more than 5 seconds at full power at a time, the engine will break down. That engine is not intended for 200hp load for minutes. It lasts best when you always drive at less than 100 hp, and you drive at most half of the maximum rpm. So no bigger turbos, and it would almost have been good if you hadn't repaired the supercharger hose...!
