A new marine distributor or component for your boat may be needed if it doesn't start, it's running rough (misfiring) or stalls. Here are a few things to check: The cap and rotor could be bad, a module if its electronic distributor or your points and condenser could also be acting up.
Note: An automotive distributor is NOT for marine use. We Do NOT recommend using one for your Inboard boat.
