How 2 Buy
Unique Diesel marine knows extensively how to properly rebuild to near-new condition a Peninsular engine. On this page you'll find and learn about what services we provide existing Peninsular engine owners in regard to restoring their Peninsular power plant.
Above is a Refurbished Peninsular engine displaying the workmanship that goes into restoring these engines back to excellent mechanical and cosmetic condition. Near new condition, with many new and used components.
Why have Unique Diesel Rebuild?
Simply put: We know this engine inside and out and there is no one else around that is more qualified and experienced in making things right than the actual manufacturer of these engines (that's US).
As a boat owner considering repair and replacement of an engine, consider the value in having the engine correctly rebuilt and upgraded without the unknowns. Each engine assembly is professionally rebuilt using correct materials and processes. The engine is then test run at our facility to ensure that the engine is without leaks, runs properly, timing is set for performance and emissions and is known right before it re-enters the vessel.
As a boat mechanic, consider the headaches you'll avoid by having the manufacture worry about parts sourcing and the logistics of cleaning, parts inspection, assembly and testing. Avoid putting an unknown into service only to be responsible to the customer for any defects. There are many assembly surprises surrounding the different generations of engine you may be working on, and certain updates you won't be aware of. Compounding this whole issue is that Peninsular Diesel never maintained a service manual to assist in assembly and take apart, that makes it harder, much harder. Much simpler to remove and replace when engine is ready.
What's included in our Service?
Each engine assembly is taken completely apart, all marine components will receive some form of cleaning process from bead, soda, sand, and chemical. This allows us to take the parts that will be re-used back to the base material for proper inspection and future painting. Parts too far gone are simply replaced with new. Components that are re-used that can be pressure tested are also tested for leaks and defects that will affect usability.
Each complete refurbished assembly will receive a new longblock, as seen already on this store. This will be the basis, so the heart of the engine assembly will be brand new. We won't mess around with rebuilding an already worn out engine with likely known defects to the year range the engine resembles. 6.2L engines will automatically be upgraded to 6.5L engines with this process.
Other wear items about the engine are replaced. All hosing and hose assemblies are replaced, the turbocharger is discarded and replaced with new current generation (likely an upgrade from previous unit you have). The air cleaner assembly (yeah that rusty thing you have some foam on) will be replace with a new assembly with new foam element. The heat exchanger (radiator) will also be replaced with the premium CN version of the cooler, won't even bother testing your old, it'll be discarded. The oil and transmission coolers (standard) will be replaced as well. Most wear items, the engine coolant pump and sea water pump will also be replaced with new units. Electrically the engine will receive a new alternator and new starter (and be upgraded to gear reduction and soft-start system). The engine will also receive a new wiring harness and the update components to the glow plug timer setup. Instructions will be provided to integrate the improved glow plug control into existing instrument panel. The fuel system will also be replaced including a new injection pump, injectors, and injection lines (likely very rusty on yours). The exhaust outlet (aluminum 90 off the turbo to the exhaust system) is also included, excludes stainless steel models or non-Peninsular outlets (must match units in our store).
What's re-used are the exhaust manifolds, crossover, the bellhousing, the brackets, the intake manifolds, pulleys, fuel and emissions tubing, lots of bolts, oil pan, and the aftercooler assembly is taken apart and cleaned pressure tested and re-assembled.
Optionally, you can specify just replace all the marine exhaust manifolds for a pro-rated fee, and the after cooler assembly for a pro-rated fee.
What's all this cost?
As you've read above, an extensive amount of labor is involved in restoring these engines, and an extensive amount of new components are used to make this a nearly new engine as the wear items are replaced with a clock of zero.
Lead time is approximately 8 week once your unit is received.
Fixed price includes the possibility of one failed exhaust manifold will be replaced without increase.
Pricing excludes missing items from engines, requested manifold replacements, aftercooler replacements and upgrades from 6.2L engines to 6.5L equipment. Excludes cost of shipping and crating for shipment.

Do you offer an exchange engine?
Sitting on pallet ready to go? No, sorry not really. Here's why. There are changes to the engines over the years that cause some complications and there are bracket and accessory differences, things like turnaround sea pumps vs standard pump configuration and power steering in some uncommon configurations. Fuel systems, since these engines were made from 160HP non-turbo, to turbo non-aftercooled, to turbo aftercooled in 3 different HP levels, this complicates the situation some. Then, there is core availability, since we're talking about swapping used for used in many situations, we have to have a used core surplus, which we currently don't which would be sending out new components to make up the difference an receiving used back. Doable, but would obviously incur some additional costs.
In short, maybe, if interested in exchanging yours for a unit we have that has undergone what your engine will undergo, communicate that question and we will see if we can accommodate, which is likely. Will certainly need to see your engine via pictures to understand what you'll need. We do understand the downtime aspect and are working at customizing this service to accommodate.
Lead time will likely be similar to sending your engine in, except you can plan ahead and have us building the replacement (limp along with old engine) until you're ready to swap out.
What are the alternatives?
Why not just rebuild this yourself do something similar to what's offered above myself? You can certainly buy the components you need here on this store to accomplish this. In the end you may save some money, or you may not, but we certainly understand that our complete service isn't for everyone. The rebuilding service we offer replaces some parts with new that could be rebuild, we option to not rebuild some parts because the failure rate is higher and we want to avoid that will affect long-term use and create warranty issues. With that said, we are also in the parts business, as can be clearly seen on this store. So please, buy your components you need here, they will be the quality (and same stuff we use ourselves) you'll need.
What about conversion to another Diesel engine or what other options exist? It's 2020 and there are certainly some options and things to consider. The Peninsular Diesel engine is a mature platform that has seen some great evolution in the over 30 years the platform has existed. It's scraped it's knees some various years (in the beginning, and especially in the mid 90's) but got back up and applied a super band-aide that not only healed but grew stronger with improvements. Currently, the Peninsular series engine offerings by Unique Diesel - Marine are the best generation yet. But, they're not priced like they were in the 90's because they're not a budget cheap engine, not any more, they're a solid, reliable, known simple engine.
Being it's 2020 there are some real things to know. World-wide emissions laws have been adopted that require Diesel engines to be cleaner in many ways, these changes are only a few years old yet but have major implications.
If you consider replacing the Peninsular Diesel engine with another Diesel, this new diesel must be a Tier III Emissions Diesel engine, doesn't matter that your vessel is a 1980's model, the conversion must comply with current emissions just like a brand new vessel. These Tier III Diesel engines do exist and are no where in the ballpark similar in cost (much more) to what you currently can achieve with sticking with our Peninsular in cost of ownership terms. Other's Tier III engines will be more costly due to the emissions equipment and incorporating Exhaust Fluid. Yep, another bottle of consumable on board you have to keep track of, beyond buying Diesel fuel. And emissions equipment always means more stuff to go wrong.
The costs associated with converting to current/modern technology engine from another manufacture will include the engine, the labor to install the engine, the marine gear replacement (likely) and the prop replacement, and of course all the electrical, exhaust and other things that will likely come into play that will change. Many times I've seen this figure approach and exceed the 100k mark. Re powering with a new engine from another manufacturer will be costly, and may change everything you currently like about your current vessel's character and drive ability.
Do your research. If someone tells you that this emissions thing doesn't apply or tries to sell you a non Tier III engine for retrofit, they're not legitimate and they could cost you some serious money and your vessel.
Can I keep my Peninsular with these new Emissions?
Yes! You can repair and exchange for like-for-like and keep all the benefits and familiarity you currently have with your vessel and engine combination by sticking with the Peninsular by Unique Diesel - Marine. You can even get upgrades in reliability and performance.
Now that you've seen the sticker price, and read and considered what's presented here, get in contact with us to schedule process and discuss options.
