I don't remember if this link has been posted before or not.

Ernie,
That's a great link!
Mystic received a large grant to make their museum collection "available" to the public online. Largest project of its kind ever undertaken by a major musuem. This must be part of that project.
Regards,
Andrew |

Need information on Lathrop engine, supposedly 4 hp. I'd like info on rebuilding the engine, including parts list, etc. Was used in an old boat in Rocky Harbour, Newfoundland, Canada. |

Bob,
I sent you a separate email... I have some Lathrop literature I can copy for you. Also you should have the Palmer Handbook and Stan Grayson's Old Marine Engine book if you don't already have them.
Also your question should have been posted as a "new conversation" by scrolling to the bottom on the "one and two cylinder engines" topics page.
If you have specific questions about the engine go ahead and post them... pictures and a serial number are always of interest too.
Regards,
Andrew |

Here is a link to some more of the engine descriptions in the Mystic seaport database. Some of these don't have pictures. It seem that the ones in their "highlights" page that are the ones with accompanying photos:

Gentlemen:
I realize this site gets good readership and I would like to call upon you "pros" for some advice.
I am planning on purchasing a 1967 Century inboard Resorter this winter. The engine is NOT closed cooling. The current owner said he has had it in brackish and salt water for about 6 hours total since ownership.
QUESTION: Is their an advantage to having a closed cooling system (exchanger) versus a raw water system? Is their more destruction and maintenance expected on a boat running a raw system in predominantoly fresh water versus a closed system?
I thank you for your response. (Engine is an Interceptor V-8) |

Bill, I'm just thinking out loud here but with a newer V8 engine, wouldn't you want the better cooling and system protection of a closed system? (antifreeze (50/50) solution). You would also be free of clogs caused by weeds or flotsam (cast off bikini tops, etc.)
Draining a raw water cooling system is not always as easy as it would seem since the rust and debris in the jacket can trap enough water to cause a freeze crack. |

Thanx Tom for your insight. Would the Interceptor retrofit a closed cooling system without having to remodel the boat i.e. making the engine box larger to accomodate such a system?

Sorry, I roared past the line about it NOT being closed now. Probably too much to build in all that it would take...unless someone who REALLY
knows about it could reply. |

The heat exchanger for my 455 Olds is about 5" dia. by 16" long. it fits horizontally over the reverse gear just aft of the distributor. It was made by Sendur. The seawater pump is 1-1/4" Jabsco and I fresh water 50/50 cool not only the block but also the manifolds. Sea watercooled risers. Really doesn't take up much room and the 50/50 antifreeze avoids draining the system in cold weather. Just drain the sea water side. |

I never stopped to think that a water to water heat exchanger would be tiny compaired to a radiator for such an engine |

Another advantage of the heat exchanger I forgot to mention you can put in a 190 degree thermostat and the engine will run more efficiently. In a cabin cruiser you might want to run at 165 degrees to lower the radiated heat off the engine block. Not a problem with an open cockpit installation. |
