i am new to these engines, i bought a 4 acadia in great shape, and working, i have also bought a 20 ft motorboat and am in the process of fiberglassing her now, boat is also in great shape. glass just is to preserve her for a long time. i don't know what kind of grease to use in her cups, and i don't want to take a chance on using the wrong type, any help is appreciated. also looking for some parts or complete engine depending on price. i am in central newfoundland |

I think you will quickly regret fiber glassing your boat if it's wood.Glassing promotes rot and a stiff riding hull-turn back now if you can.... |

Almost every wood boat restorer including myself will tell you never fiberglass a wood boat. a wood boat was designed to flex. I agree with Bruce Hall, the boat will become stiff and will not have that nice easy and comfortable ride that it was designed to do. You would be better off if you used the boat as a mold and made a fiberglass hull from it. |

I use old style water pump grease. You may be able to get it from Bob's Antique Auto Parts Inc. PO Box 2523,Rockford, IL., 61132
Tel: 815-633-7244, Fax: 815-654-0761
888-663-3581 Toll Free. Tube about the size of a small caulking gun tube.
It seems to work better than wheel bearing grease which is much thinner. Keep in mind in operation you should give the grease cups on the crankshaft a 1/4 to 1/2 turn about every 20/30 mins. Hey no one ever said running one of these old timers in a boat was a walk in the park!!!!. Myself I stick with 40/1 SAE 30 non detergent oil/gasoline mix. Others use modern two stroke oil 16/1, I think. Guess it depends on your age. |

I have been using some Molybdenum Grease on my 8 Hp. Acadia with apparent success.
Almost any grease will work for these crude engines. Back in 1904 things were not as sophisticated in the lubrication world as they are today.
You could also used a Lithium Grease which is available at any automotive parts store, etc.
The main thing is to give the caps a 1/4-turn every time you run the engine. If it is running in a boat for an hour or more at a crack, give it such a twist every hour or so.
This will prolong the life of your Babbitt bearings. It will also help to seal the crankcase. Otherwise, the oil/gas mixture can squirt past the bearings and eventually "wash" them clean of any grease. In the long run this is not good. However, Babbitt being what it is, the engine will run for a long time without "any" grease present. A thin film of grease and oil will persist that will protect the bearing and shaft.
So there you have it.

You can search for lubriplate on here and find a ton of info.
Specifically take a look at this one.

I had to take the 3 HP Gray out of my boat and clean the grease channels out. Grease cups should NOT need anything other than your hand to turn to lubricate the mains. I use plain old wheel bering grease from the auto parts store.
Lubrication technology has changed and for the better I might add.
Hope this helps

sound good, i was told wheel bearing grease was ok to use but i didn't want to try it, not being sure, and ruin my bearings. |

An additional note my 3 HP Gray is an NOS engine not rebuilt but NOS so the mains are tight. On an engine with some wear the thicker grease may be ok. I say may because you need to confirm that it is actually getting into the main bearings. Also on an engine with wear thicker grease will assist in sealing the main bearings to the crankshaft. |

Hey Matt I have a 20 foot motor boat with 5 layers of fiberglass no wood and i find her just fine. About the grease, wheelbearing grease is fine, it keeps a car on the highway doing 100 km/h so i'm sure it can keep our motors going. |

If you have a NOS engine that never had salt water in her you have a rare thing indeed. Whatever you don't don't let salt water get into her now. Put on a keel cooler and run anti-freeze.
What's the hull type? A Bush Island Boat sort of shape? |
