I posted about my 1924 Gray Model U about seven years ago. I had several project ahead, but finally got it on the work bench today! I has good compression, and appears to be complete. Is there any manuals for these "out there" for these engines? I'd be particulary interested in how the water pump is plumbed, ignition system works, etc. Also, were the carburators gravity fed from the fuel tank, and if so, where were the tanks typically mounted in the boats?
Also, and general tips on working on these types of engines appreciated. Thanks, Tom |

Tom, one place to start is:
http://www.oldmarineengine.com/technical/rad_tips.html This is written by Mr. Day - an expert.
Then go to: http://www.goslowboat.com/
Hope this helps |

Tom,
I don't have a manual but I do have a "U"
in a boat.
Give a hollar if you want

Dick, thanks for this links. Lots of great information on both links! The second link has an article on how the three port, two cycle engines operates, and it was very timely, as I tore the cylinder off today, and scratched my head for quite a while trying to figure out the porting operation. It still baffles me as to why the intake and exhaust ports open to the same chamber.
Ernie, do you have any photos of your "U" and boat online? If so, I'd love to see them. Thanks, Tom |

Ernie, Nice boat! Did you get it in the water yet? I'd like to eventually put my motor in some kind of wood boat, but for now (when I get it back together)I need to make some kind of test stand. I understand that these engines shouldn't be run without a load on them, i.e. a prop in the water. What could I rig up on a test stand for "load"? Thanks, Tom |

My "U" doesn't run any different with or with out a load. That was one of the biggest suprises when I put the boat in the water.
Some small marine engines are pretty jumpy but the "U" is docile either way.
Hope this helps

Thanks Ernie, I was afraid that the first time I started it that it might jump around the garage like the Easter Bunny! |
