| My 76 SN doesn't have a main circuit breaker (or main fuse)that I can find. Somewhere along the line, a previous owner or service person must have eliminated it for some unknown reason. I have never had an electrical problem in the past six seasons I have owned the boat, (I did replace all gauges three years ago) and have never even blown any of the dash fuses. That said, I would like to wire a main breaker in for obvious reasons. Can someone advise where it should be wired in? Thanks in advance. |

6strings, My 77 doesn't have a main breaker on at the engine ether. Early boats were real light on fusing. My 54 has absolutly nothing and my 64 has what looks like a open melting link screwed to the back of the wood dash with wood screws. I wouldn't worry about yours much. At least you have fuses like my 77. Oh, by the way, do you have a fire extingusher on board? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| Interesting. I hadn't really worried about until I read the other thread here. Yes, marine extinguisher close at hand! Thanks Pete. |

My 76 Mustang with the PCM 302 had a factory breaker in it. The purpose is if you have short anywhere before the fuseholders in the dash, you will have a meltdown!!! Have the fire estinguisher ready and if gets into a fuel line, might as well put a marshmallow on a stick and enjoy.

6strings, the main breaker (on most configurations) is in the charging circuit between the alternator and the battery. Earlier boats (and many cars too) didn't use as many fuses and circuit breakers as modern vehicles do. Of course there was alot less electiral items on vehicles then also. ------------- 95 Malibu Echelon w/Mercruiser 350 Magnum Skier Former boats: 88 Ski Centurion Tru Trac II 59 Chris Craft Capri (woody) |

| Thanks guys. I would like to wire one in. I guess when I uncover the boat I'll take a look at it and see if I can figure this out. The bracket for the "fuse block" is still where it should be on the back of the engine where the solenoid, ballast resitor (no longer used due to electronic ignition) and voltage regulator are located. I'll probably have questions. Thanks again! Love this place... |

Consider this...
Lexan panel, hinged to intake. The lexan can be tapped making it easy to mount the electrics. Battery disconnect. Circuit breaker, terminal block. ground block. ignition. Wire loom. purdy. The 30A relay powers the alternator and electric choke, reducing the load through the harness and ignition switch. The battery disconnect it great if things went awry. I use it every time its mored  ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

Nice! Did you design and build yourself? I do like the idea of a battery disconnect. Would be much simpler than manually disconnecting every time I'm done using the boat (which I always do...for peace of mind).
Also, I've noticed in several of these pics that many of you have your flex exhaust hoses wrapped in carpet. Don't the hoses get pretty warm, even with the water flow? What is the reason for this? Thanks! |

Ya, just thunk it up. Funny, once one organizes the harness all pretty so its easier to diagnose future problems, there are no problems. ironic.
I see the carpet wrap from the factory on a lot of old inboards. The heat is never an issue unless there is no water then there are bigger problems than carpet, like sinking. A long as the hose stays wet, it can't exceed 212 degrees. its usually much less, I think the carpet it is wrapped to attenuate noise. If you are using a high quality, thick wet exhaust line, the carpet doesn't do a whole lot. Some boats have cheap thinwall hose that you can feel bulge every exhaust pulse, then the noise is significant. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing."

Gotta,
Yeah, I remember the first time I changed the impeller in my pump, I put the pump in upside down. My brother-in-law started the boat at the dock while I parked the truck. When I came down, there was smoke coming from under the engine cover...duh. I shut it down, probably just before any major damage was done. I switched the pump around and everything was fine. Just lucky it didn't burn up the boat, the dock, and everything else! Lessons learned the hard way....that was before I found this place! |
