These Altmount Kits by Balmar offer the opportunity to install a larger alternator than would otherwise be possible. They are designed to fit select engine models, the list expands every day so if you don't see your engine listed do give us a call. This kit 48-FSP-M4.17 is for the Vetus M4.17 Marine Diesel. Alternator upgrades using a single drive belt are limited by the amount of power that can be transferred by the belt but using a serpentine belt considerably increases the possibilities. The kits include a set of serpentine pulleys to go over the crankshaft and water pump pulley and replace the alternator pulleys and come with a matching serpentine belt. They are sold for specific engine models only. The alternators need to be purchased separately. If you order an alternator with a kit it will come with the appropriate pulley pre-installed. Installation is relatively easy. Each kit comes with two belts. We don't recommend you order additional belts until you check the fit. Installations vary and sometimes we have to swap out belts. We will swap unused belts for free we just ask you to pay shipping.
