Product Overview
A slow crank, a heavy click, or silence at the starter can stop a boat trip before it begins. Once the batteries, isolator, cables, grounds, start relay, and engine rotation have checked out, a worn starter is the next practical repair—not another round of guessing.
This 9-tooth clockwise starter is designed to crank compatible four-cylinder Volvo Penta D2 engines. Matching the power rating, pinion, flange, mounting holes, terminal position, and original reference number is essential in a marine engine compartment.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Production date, serial number, engine option, dimensions, connections, and previous repairs can change the part used within the same model. Compare the removed item and service information before purchase.
Frequently Asked Questions
Q: Will a new starter fix a single-click condition? A: Only when testing identifies the starter. Low battery capacity, cable resistance, a relay fault, or a locked engine can create the same click.
Q: Is this starter suitable for every Volvo Penta diesel? A: No. It is intended for the listed D2 engines that use one of the matching reference numbers and the same 12-volt mounting arrangement.
Q: What is the safest way to confirm this fits? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.
Q: Who manufactures this service part? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
