Marine

In late 2017 Peninsular Engines Inc. closed for business ending a long involvement in marine diesel propulsion using the General Motors designed 6.2 and 6.5 diesel engines since 1984. In early 2018 Unique Diesel purchased all Peninsular Engines, Inc. assets, which turned into parts support for Peninsular's inboard marine diesel engine platform. This marine and manufacturing undertaking was extensive and challenging and far outside of the scope that UD desired. Continual challenges to existing marine supply chain and forced changes in manufacturing sources became too much. Eventually, a crippling issue occurred in our ability to continue producing many proprietary parts, and without the capital and desire to reinvest in the platform could not remain in the form it was. After working from 2018-2024 to create a near complete parts source for the marine platform a hard decision was made in 2025 to drop support for the platform closing udmarine.com and shift major focus of the business back to automotive. After some time to restructure direction and consolidate our web store presence it is now possible to offer a very small amount of supplemental marine components here. Our goal is to interest a stocking distributor to handle the Peninsular parts product line. If you are looking for components not found here, contact your favorite Marine Parts distributor and request components be handled by them. Customer Service emails will be ignored when they are for requests for items clearly discussed on the following page as no longer available. More about this here:
