I am in northern B.C and usually putter over a new boat build in the winters, mostly very practical boats that serve for fishing/hunting/work. This winter I have been planning ahead for next winter's project (or the winter after) I want to build a small 'just for fun' boat with local tamarack and wrap it around a st lawrence/baxland......
I want to build this boat around an antique 2-5 hp single (or possibly 2 cylinder) gas inboard.
I have been browsing this forum alot and getting serious fits of envy over lots of models.
What I am hoping is that those experienced with these types of engines could give me some advice on what I should be looking for interms of an engine that I stand a decent chance of rebuilding to usable condition, mating to a gear box (or as a direct drive go only unit.) I'd also be happy to set it up with external battery ignition.
I expect to spend some money on the project but would like to start with an engine that will soak up less then more. I don't have access to machining here but am half ways smart about restoration processes. (usually break slightly less then I fix)
Love to hear what you figure I should wrap a 12-16 foot lapstrake picnic boat around. The engine is the prime focus and the boat is simply a way to enjoy it. (and to justify it to SWMBO)
I am not set on needing to restore an engine if there are models out there that can be found in near running condition I'd be happy to get one that just needed love and cosmetics. |

There are some 5hp Du Bries around that are new old stock.
Someone found a cache of them a few years ago and there are some for sale They are 5hp four cycle.
I bought one still in a crate to use in a boat and decided to leave it in the crate for display. I went looking for another from the same group and found 3 for sale, one that was one number away from the one in the crate so I bought it (it had been taken out of the crate and run once)and will be using it in the boat along with a used gearbox I found.
If you look around you'll find one.

Thanks Lou, I did some reading on here and found refrence to these engines. 42 interchangeable ford parts is pretty neat. Might be more motor then I was originally thinking but will try and track one down. |

If you are in BC why would you not want an engine built in BC ?
The 4hp Easthope with built on clutch would be perfect I would think |

For a boat the size you are describing, the most common fitting was a Briggs & Stratton marine conversion of the kind done in the 40s to 60s. I have one here by US Motors Inc. It uses a cast iron B&S with a wider engine pad that includes a marine base/pan with four bolt holes and is angled downwards for shaft alignment. There was an outfit in Vancouver building these some years back; a short video used to appear on the Knowledge Network sometimes.
Not my taste, but to some people that's a vintage engine and no cooling issues to deal with. A lot less weight too, so if you do get swamped your chances of staying afloat are greatly increased! 
If you'd like the convenience of an outboard with the vintage look, an early Seagull is hard to beat. Something like the SD model. They polish up beautifully. |

Thanks for all the suggestions/help. I am going to keep researching/learning and hopefully something classy will surface. |

Almost any 2 -3 HP single cylinder engine in working condition ( maybe not full bling) will do.
In a 12 to 16 ft lapstrake which is to say, dainty, boat, a copper jacket Waterman, would do just fine, something along the lines of a DisPro boat.
Whatever design you make, just make sure your engine bed is beefy - the single cylinder engines can shake the boat quite a bit, especially if there are no counter weights on the crank.
Once you get over the notion of having a transmission, you'll find that it's far simpler than you think. Learning to reverse on the switch is relatively easy and will help you a lot.
Simpler , in your case I think, is better.
Modern batteries give you plenty of range per charge, and will even let you charge your cell phone - no need for a generator or alternator - just charge it up on shore.
Oh, final point, plan on having a couple of oar locks built into the hull. There are times when the small engine is just to noisy.

This might provide some thinking . . .not quite what you had in mind but simple, clean, workable and stable

Many Atkin small boat plans suitable for inboard engine installation are available at nominal cost. Study plans are also available at about $15.

Thanks for the advice. I am all for simple. Direct drive would suit me just fine. I have been doing alot more research and am now a man who will never let a thrust bearing equipped engine pass me by if I have a chance to buy it!
Re the oar locks: You are cetainly preaching to the converted on that score. I collect sockets and locks like an addiction and do a bit of oar carving when the right wood comes along. My current thing is scull oars (the over the transom type not the racing).
BCM:
Great link, I had never been there before, some very smart hulls. I had up to this point been studying John Gardner's dory book and Howard Irving Chappelle.
Thanks a bunch guys, I am smitten with these little power plants and can see that no matter what I do or do not end up with in a boat I am goinf to someday need a show piece. |

David,
Here's a site with information to add to your knowledge of old two-cycle marine engines.

David, Easthope engines were built in Vancouver1900 to 1968. 1911 they quit 2 cycle engines in favor of 4 cycle which worked much better with the carburetor of the day. The 4hp model would be the one for you. It has a built in clutch (fwd neut rev) and has a Wico EK magneto. Add gas and cooling water and you are on your way. No batteries, coil, or wiring to worry about. The 4hp (referred to as 4-6 hp) runs between 100 and 700 RPM and weighs 240 pounds with clutch. The single cylinder Easthope engines were balanced to reduce vibration. Weighs 240 pounds. |
