Hi everybody
My name is Tim. I've built a few boats over the past handful of years. I have in mind for my next project an classic power dory. 18 foot, 6 foot beam, displacement hull made to cruise at around 6 knots or so. Would have originally been powered by a single cylinder, low rpm motor with a large prop from what I understand. Today's motors just don't seem right for the boat and are high revving for planing. It sure would help me to realize the project to be able to find the right type motor for it. Where do you think I might find a single or two cylinder, low HP engine suitable for this boat? I want to be able to use this boat for pleasure cruising and fishing - not a trailer queen, so I need a good working reliable motor for it. This seems to be the right place to ask here - any ideas?
Here's a pic of the boat I'm considering.
Thanks in advance for any help you can offer.

Tim:
I am in the same " boat" as you. Displacement hull build in my future but finding the engine, gear box, shaft, prop, stuffing box etc takes time and dollars.
I have been reading everything I can (start with Grayson's book) haunting this forum for a couple years and am just starting to get an idea of what is involved.
Has not diminished my admiration for or desire to own an antique or classic inboard but there are some checks on the minus side for building/planning around one.
My own stop gap measure has been what I think is a reasonable approach. Antique outboard that was built to run at 1000 RPMs, Uses battery ignition and all he cast iron charm we love.
Advantages: you keep oil/gas mostly on the outside of your bilge. No holes in your keel, planking etc. No burning hot thing in your boat. More space inside the small boat so you can build smaller (i.e more money/time for quality)
No fear of stuffing box failure while moored for long periods. Easier to beach/trailer. No need for rudder hardware/rigging. If you pick the right one you wont even need to worry about water pumps.
The biggest one for me is that if we take a rare antique and relgate it to salt water use we are either destined to spend alot of time and effort protecting it from the caustic ocean or we are using up heritage. A 90 year oldbard can be brought home and easiy flushed at the end of each day.
Dollar wise you can outfit with 3-5 hp 90 year old outboard that comes ready to serve for decades for very cheap money. |

Thanks for the response David.
I do have a British Seagull 40+ that I have thought about using, in a well. It is in perfect running shape. Has an antique look to it, even though it is a '72 year model. And they are made for displacement hulls. I bought it for $175 so very cheap power. So it is an option, but it would just not have the same coolness factor as the inboard. I'm sure that makes sense to you, being in the same boat, and all.
Seems like it could take some time to find the right power plant - or maybe not at all. I won't "give up the ship" just yet though.
Then of course it makes no sense for me to start building the thing without the power plant in hand first. There is no rush, but having the engine would get the ball rolling for sure. Thanks

The more common engines are available and should be fairly reasonable. Lockwood-Ash was a popular brand down here, good runners and very durable. They were sold as Motorgo through Sears, later Nadler made the same motor under their name. Detroit, Caille, and Gray were also good motors. Palmers, Acadia, and Atlantic on the east coast. The problem with these is finding one that didn't run in salt water, you want to be sure it was a fresh water engine. The most common engines are the single cylinder in the 4hp range. |

Not exactly sure what you are after or where you are, but there is an auction this Sunday in NH - several restored engines - check it out:

Bring cash to Ernie's and be done with ! You wont do any better then that. 600 miles would not be too far to drive. 1000 would still be worth it.
I am very, very jealous.
Just to be clear I was not thinking 1-2 hp Seagull. I wont sell the notion too hard though cause no sense creating artificial demand. |

Tim,
The image of the Toppan Power dory is from John Gardner's book Classic Small Craft you can Build.
To assist your research here is at first page of an article that describes construction of a power dory using John Gardner's plans. The boat is powered by a 3HP, 800 RPM two cycle engine. Boat speed is 5.5 knots.
More info here www.goslowboat.com

Depending on where you are, there are wooden hulls that can be rebuilt assuming that you have the boat building experience - you seem to have that.
Modern materials will significantly help a rebuild.
Have a look at

I think he may be flexible on the price he's asking.

Call the following number401-741-1517, and ask for Fred. He has a NEW Atlantic with all of the marine fittings and coil etc for your project. This example is from the old patterns but was made in 1966! Old style, old behavior, old sound, new condition and reliable with no fuss. |
