This is new. Also doesn't charge at start and stays at battery voltage til you rev it once.
At 3100rpm cruise.
New Alt time.

How do I tell which alternator I have? There seems to be 2-3 different types. |

Another false, misleading statement by ric. FACT: Marine alternators and the Autozone units will both do the same job of generating electricity, the critical difference is the ignition protection. Marine electrical components are shielded or screened so that they cannot ignite fuel vapors. USCG requires ignition protection on inboard boats. Automotive alternators ARE NOT ignition protected or USCG approved. |

Marine electrical components are shielded or screened so that they cannot ignite fuel vapors. USCG requires ignition protection on inboard boats. Automotive alternators ARE NOT ignition protected or USCG approved. You've been drinking the boat repair shop juice for too long. You didn't even read what I said. On Delco style alternators as used in Volvo Penta it is the automotive alternator. In order to make it ignition proof, they designed and added a screen spark arrestor to the back of the unit. Internally they are identical to all other Delco alternators. Adding the ignition proof screen to a automotive alternator makes it USCG compliant. The screen is the part that is certified to work on the alternator, not the whole alternator itself. Hence why 1000 shops sell rebuilt marine alternators all over the net for $80. They just add the USCG certified screen to a standard rebuilt alternator. Here's a good shot of one style that has it externally. Others are more discrete on the back case cover.  Same alt without rear marine case:  Want a good laugh? On the parts book for Volvo Penta they sell every internal and external part for the alternators, except the spark arresting cover. Why? Because people will just NOT buy their $400 "marine" alternator when you can go buy the same one for $80 and add the $10 rear case. |

Hey Guys, What is it about Captain Morgan and Ric? They never agree about anything . Are they Father and Son ? "You old guys know nothing but think you know it all" "You young guys think you know it all but know nothing" Nothing negative aimed at either of the two !! I am not their Grandad, I live at least 3,000 miles away and never visited the USA until 2001 ! Graham |

However, it would be my tech who has the final say and he knows when to install marine vs. automotive parts. For my generator fuel pump, he went with non-marine but with my twins, he has gone true to what was on the engines. I would want the same equipment on my engines unless a good argument could be made and price is not a good argument. Too much to lose just to save a few bucks IMO. |

I was simply pointing out the differences. It's not black magic, it's just a different rear case. Marine Alternators vs. Automotive is about a $10 difference for a reman with a 1 year warranty so just buy the marine one. If there was a $100 difference I would buy an automotive one and put my worn out alternator's case on it to keep the ignition rating. You could EASILY purchase a higher amp alternator not easily available in the marine catalogs and do this same thing. And yes, it's all about the price of stuff. My father didn't raise a fool. |

I hear you ric and I think this argument will be settled by a couple of the techs that we are fortunate to have on this site. Regardless of their opinion, I will probably err on the side of caution just because I can. |

Personalities aside, I think the most critical issue is to insure whatever alternator is used that it be considered safe by a trustworthly knowledgeable source. In addition to potential insurance issues should anyone be injured, gas fumes in bilges with any component that could provide a spark that is not marine certified or equilavent could be deadly. My 2 cents. Mike. |
