In order to run, your boat needs a working diesel engine, but for that engine to operate effectively and optimally, you’ll need additional parts and components. These, in turn, keep it happy. The Volvo parts we have available here offer everything your engine could need. Ensure that your engine is safely cool with a heat exchanger, apply a draining nipple so that it never overflows, and properly seal it with an o-ring. All of these components will make for a happier engine, boat, and, in turn, you.
