With a D3-110 you have an engine block that has a bigger installed base than lots of other marine engines. Virtually all larger Volvo cars with diesel engines in the approx 2005-2018 were equipped with this block.
What make this engine problematic is the tolerance for poor maintenance. It has very little. This is valid for all common rail diesels. In return you get amazing power and torque from a relatively light engine with little vibration and good fuel economy. And yes, you also get better emissions but that is of little use for the individual user of the engine. Still relevant though.
So as said by others you should take exceptional good care of the engine to keep it happy. Make sure you use proper diesel additives to prevent diesel fuel problems. Use the correct filters (also for the racor), change oil regularly. Check the engine at regular intervals when running for long periods, especially the raw water pump. Keep an eye on the coolant temperature and familiarize yourself with the temperatures of the coolant relative to the engine load. This will give you a hint if the cooling system is clogging up.
Make sure the waist-gate of the turbo works well and is not seized up. You can feel if the turbo spins freely by removing the air-filter when the engine is off.
Listen to the engine when it is running and learn to known the normal engine sound. When it changes find out why. Do not wait until things take a turn for the worse.
I’ve heard Volvo Penta is taking the engine out of production because Volvo cars is no longer using it in any of their passenger cars. A direct replacement is not yet announced.
