It was nice here today so I got the Fantail in the water.
Over the last couple of days I got the engine to start, run and reverse on the switch real well in my yard on the trailer. I was really suprised to find out it didn't run any differntly in the water. I didn't even need to change any of the carb settings. I guess I was amazed everything worked as advertised.
More pics from when I got this boat till launching are click here

The fuel system is a plastic outboard tank under the bow seat. The little square thing on the engine below the timer is an OMC fuel pump. The pink things are absorbant pads. However I almost have a Schlebler that doesn't drip now that it has a viton tip needle and new brass seat. So maybe I won't need them any longer.
You will note the coil box is in different places in different pics. I wasn't sure where I wanted it so I put long wires on it. I think I will leave it that way so it is convient to where the boat is run from. Using the boat alone I sit in front of the engine on a little stool. If there are others in the boat I run it from behind the enigne. I am running it with a Ford coil and gel battery.

Great work Ernie. Are we going to get to ride in it at Mystic? Looking forward to seeing it and riding in it. |

Went out today and took my GPS. Calculated hull speed is aprox 5.5 knots or 6.7 MPH.
Doggone if it doesn't do that.
Max I could get was 5.4 Knots and then I changed the GPS to MPH and got 6.7 MPH. However I think I may try a smaller prop. The engine doesn't rev up much. (havn't taken my tach out with me yet)
At idle barely running it is still going around 4 Knots. |

Ernie, what prop do you want to try, may have something, could bring it to Mystic. Diameter, pitch, 1"tapered shaft? Most I have are three blade. |

JB,
I have a 13x13 3 blade 1" shaft on it now. I am thinking 12x12 3 blade. I have an 11x11 and a 10 by something. The shaft is actually 7/8 but I have been using a bushing to 1 inch since 7/8 props are not all that common. It's all a guess anyway so you can see my thinking. A little more RPM won't be a problem since it doesn't rev up much now.
Thanks
Ernie |

Ernie,
I am very interested in learning more about the innovations that you added to your Rose launch.
1 Fuel pump with Schebler model D carburetor
Do you know a part number for a low pressure crankcase driven pump that is commonly available that includes a hose or NPT crankcase connection. I suspect that most pumps are flange connected. I would like to purchase a pump and experiment with it using my test bench, then maybe add a pump to my boat engine.
Using a top mounted fuel tank connection or portable “outboard” fuel tank has an appeal.
I would have thought that the high pump output pressure compared to gravity feed would increase Schebler float valve leaking, however you report the opposite. Can you enlighten me about this as I am also very interested in ways to eliminate Schebler model D dripping and/or leaking.
2 Viton float valve
How did you manufacture the valve? I attempted to manufacture a valve using Viton for the seat but found it too rubbery to machine. I am currently experimenting with Delrin seats but this material while easy to machine does not have the desirable “soft” properties as does Viton.
3 Exhaust
Your exhaust set-up is most enlightening as the muffler is below engine exhaust outlet, below the waterline and below the through hull. This is a great method providing the muffler and horizontal exhaust pipe do not fill will cooling water as to present back pressure during starting. I’m guessing that cooling water collects in the bottom of the muffler when engine is shut down and does not block the exhaust. Your method is a major advantage as it avoids exhausting through the side of the hull which encroaches on passenger space.
4 Propeller
Just for information, I use a 12D x 14P three blade. My engine is similar to yours, 3 1/4 B X 3 1/2 S. The propeller hold max RPM to 850. The vessel drives at hull speed. For my engine 850 RPM is the engine speed that produces maximum torque.

Barry,
1 fuel pump is from a small OMC (Evinrude/Johnson) outboard. NAPA sells them cheaper than OMC. For an exact model tell them you want a pump for a 1970 6 hp. They flange mount so I used a pice of 1/4 thick aluminum drilled and tapped for the pump screws and drilled and tapped 1/8 pipe for the connection to the crankcase. The pipe to the crankcase has a blob of solder in it that is drilled .029 to restrict crankcase pressure some.
2 Needle and Seat
I knew someone was going to ask about the needle and seat. I have no idea what it came out of. My best guess is an Echlin (NAPA) carb kit. The bag is marked GO 25-316A
I cut the nub off the needle that held the float spring to shorten the needle as much as possible.
I set the carb up in my milling machine and milled the existing Schlebler seat area flat. I then drilled and tapped for the seat. 5/16-24 I think. The carb I am using as from a Cushman Binder engine and had a fabrucated float arm. I modified it to push on the needle. The Cushman carb also has a conventional throttle plate. I think the throttle control is better than the traditional schlebler style.
3 The exhaust is just what I have seen and used around New England all my life. It should have a vaccuum break in the line from the engine to the water injection elbow. However the boat doesn't live in the water and the height differences aren't much. I do run the engine in reverse (gear pump so it doesn't pump water in reverse) till the exhaust gets loud (blow all the water out of the exhaust) if I am going to leave it for a while. I have had no problems starting due to backpressure in the exhaust. If by some chance the exhaust fills with water I have a drain in the muffler. There is also 7 feet of surflex exhaust hose stuffed in under the rear seat and aft deck. Between the muffler and the hose it is real quiet.
4 Prop
I have not had a tach in the boat. Simply by ear it probally isn't running over 500 RPM if that. I believe the engine is rated at 500 RPM anyway. Also this model of Gray has no counterweights or balance in the flywheel. The 13x13 prop will actually push the boat a little over hull speed. I would actually like to end up around 4.5 MPH as the boat is real comfortable there. I would also like to be able to slow it down a little more. It will be easier to dock and reverse that way. I may try the 11x11 3 blade that I have today. |

I just looked up the part in a 1970 OMC parts book. The OMC part number is (or was)
382875 fuel pump assy
Hope this helps

Ernie, I have 2 13X12LH and 2 14X10LH, don't know which direction you run you engine, we use left hand props. If you want to try them let me know, I'll bring them with me. |

JB,
I am using RH. Due to the gear type water pump I don't have much choice.
Thanks for looking

Part 382875 was superceded to:

Some less expensive OMC/Johnson/Evinrude type pumps can be see here. |

I can hardly believe my eyes.
The Rose launch and Gray engine experience has left Ernie speechless.
But that's what old engines in old style boats tend to do :-}

Hey even more so than the "mobile malt beverage storage module"
I just wish I could find time to get it in the water this year. I havn't touched since I put it away last fall. |

New battery and coil box.
I ran out of electricity once last year. Don't intend to let that happen again. Knife switches allow either or both batteries.

But Ernie - have you tested it out yet?
Summer's in full bloom now and you've just gotta get that boat wet.

Yup and it kicked my but on day 1. Dirt in the carb.
Day 2 yesterday was perfect ran it a lot and it worked as advertised.
I did pick up a nice Baldrige reverse gear at the Orange MA show. Number 5 or 6. I definatly DO plan on installing it over the winter.
Dovetail joints??? It's lucky it got oak trim and polyurethane. Cosmetics and I don't get along. The boat still has peeling blue paint on the deck. You see it's good to have future projects!
Peeling blue paint can be viewed a Mystic if they can launch it for me. |

Ernie, you're going to take all of te fun out of docking, missing reverse and taking off wide open forward. That's a nice looking gear and should make it a pleasure to handle. |

Thanks to Scott at the Mystic Seaport I finally have pics of the boat under way. The passenger is Bob Long
Pics were taken at the 2008 Antique Marine Engine Exposition at the Mystic Seaport in Mystic, CT
