Pics of new toy.
You never know what you will find on Craigs List.
21 ft long I think I am going to put a Gray 3 hp model U in it for a start. It sarted life with a steam engine in it then was being converted to electric. Now a one lunger.

Looks great Ernie! 
It's fiberglass right?
The hull looks like it has a lot of bouyancy aft which will work well for whatever you put in it.
Who built the hull? |

Yup it is fiberglass. Not shure who built it. I can find a lot of them on the NET that are similar but not quite the same. I am going to put a late Gray "U" 3 hp in it.
Same as the pics below. I can't find a pic of mine right now.

It looks like a smaller version of a Stanard Bros Ferry that operated on Sydney Harbour in the early 20th century. In fact there were alot of boats like this built in Australia. Mostly timber of course. I will try and take a pic of the 1889 version which is lying in Lake Macquarie. Sure would like one myself. |

Well it's finally getting an engine.
The engine is in place temporaryly to confirm my floor frame patterns are correct. Note the floor frames are low. It's easier to shim the engine up than to lower the floor frames. Or maybe at some time a different engine??? Once the engine is in it still needs tons of work. It include removing all the blue paint. You can see some of the seat framing is in for the bow and stearn seats.
Prop stuffing box and rudder
Waiting for the fiberglass to cure
I have finally confirmed that it is a "Rose" This style of fantail has been built by several people. It is 20ft by 4ft3in.
Currently you can purchase one from Lloyd Beckmann in Wakefield, RI

Nice work Ernie, Bring it to CMM and we can have cruise on the Creek. I have a nice copper gas tank if you are looking for one. Be glad to give it to you. but you have to dig it out from under all the other junk. |

Looks good so far Ernie, are you going to launch it this spring? The one lungers are nice, nice sound, but they can get rough at max rpm. |

Yup I hope to have it running for spring. I need to fabricate the jacketed part of the exhaust. Also put in battery and fuel. For fuel I think I am going to use an outboard motor fuel pump and an outboard tank. I have done that in the past and it works well. The Blue has to go! However that will be after it is done mechanically. The deck will never be able to be varnished. Probally paint that tan. However the coaming, toe rail and rub rail are mahogany and should clean up ok.
As to vibration the engine beds are 3 layers of 3 quarter plywood laminated with epoxy. They are bedded in some fiberglass mush so they have 100 percent contact with the the hull. The glass work is multiple layers of mat and 24 oz woven roving. All this is done with vinylester resin. Vinylester is like polyester except it is closer to epoxy in it's molucular makup. (as I understand) It smells the same as polyester, however it is a lot nicer to work with. |

Nice Job Ernie! Looks great! I believe the Vinylester does not cure as brittle as polyester more plyable but tough like epoxy. |

Hey Ernie - on my old boats, I inject the engine cooling water as close to the engine as I can.It looks like you've got a fairly long run of hot pipe before you get to the muffler. I made an elliptical hole in a standard elbow and brazed in a 3/8 pipe to take the cooling water. It is all sloped downward to prevent water getting back into the engine. I also found that using clear tubing on the suction side of the water pump lets me see if water is getting sucked in.
But a really good new toy.

Ernie,
I have been following your project with interest and much admiration.
Two-cycle engine exhaust is a subject that interests me.
Your recent image suggests muffler placement about parallel with prop shaft, therefore below LWL. The image also suggests engine cooling water will be injected into the muffler.
I am very interested to learn where you will exit the exhaust from the hull and how you will overcome backpressure both during engine starting and also during engine operation as a result of accumulation of water in the muffler that must be lifted above water line.
I have tested water lift mufflers with 2-cycle engines and am currently engaged in research and study of the issues. Your experience and be very helpful.
Regards
Barry |

Barry,
I have been installing 2 stroke engines in boats for the last 30 years. Never noticed a problem. If the engine was really below the water line I used a vaccuum break between the water injection point and the engine.
This one isn't really a water lift muffler. Still I don't anticipate a problem. Placement is more for cosmetics and quiet than correctness. If it proves to be an issue I will simply shut off the water intake before shutting of the engine. That should result in most of the water being blown out of the exhaust. Not sure where the outlet will be. Once again cosmetics. It will however be above the water line. The high point at the engine is also above the water line. There will be surflex hose between the muffler and the through hull fitting. |

I really havn't decided where I am going to inject the water. Miro you are correct it is easy to inject the water closer to the engine. I may jacket the riser. I have to decide which is easier, jacket it, heat shield it or inject water at the top (down far enough so it can't get back to the engine). I am going to use reinforced clear or a little clear water filter that I have. Maybe both for the reasons you mention on the intake. |

Hey, Ernire, have a look at the discussion our Aussie compatriots had on shaft and engine alignment
http://www.oldmarineengine.com/discus/messages/3452/101151.html
You probably know all about this, but I found it very useful as a refresh
They've got summer tme now - I've got 4 ft of snow and 2 ft of ice on the lake.
Let's hear it for global warming :=}

No snow, just the ice here. Yup warm is good.
Thanks, however as far as alignment goes remember this one is plastic. It's aligned now. I will check it once it's in the water. However I have yet to see one of these small fiberglass boats change shape when going in the water. Not saying they can't or won't, just never seen it happen. Not sure, but I think the 1st one I did was in about 1976. |

Ernie,
I have a few questions for you about your boat but berfore I ask keep in mind that I know nothing about building boats or mounting a engine in a boat other then when I was younger I built a few radio controlled wooden and fiber glass boats. How ever I do know a little about composites, fiber glass, carbon graphite, kevlar, resin's, epoxies, polyesters, etc.. learned from my job and fiends. First question: what type of wood are the two engine mounts made of? some kind of hard wood? spruce,oak? Do you have blind nuts with stakes in the two wooden rails that are covered with fiber glass for the engine bolts to screw into? Lag screws would never hold would they? |

The engine beds are 3 layers of 3 quarter plywood laminated with epoxy. They are bedded in some fiberglass mush so they have 100 percent contact with the the hull. The glass work is multiple layers of mat and 24 oz woven roving. All this is done with vinylester resin.
The engine is bolted to the bearers with 3/8 x 5 stainless lag bolts. There is 3 inches of thread into the bearers. In a fiberglass hull you use plywood not regular wood when glassing it in. Plywood is dimensionally stable. Plain oak or pine isn't and will ultimatly crack the fiberglass that is bonding it into the hull.
As to the holding ability of lag bolts, that was the primary fastener to mount the engine in most wooden boats since engines were mounted in them.
If the lag bolts are ever a problem I have room to cut slots through the bearers and slide in nuts welded to a little piece of flat plate. |

Finally all the woodwork and glasswork is done. Need to hook up the exhaust, fuel and ignition. Also heat shield the exhaust from the engine to the muffler.
Then paint the woodwork.

Finally got the new wood painted. I removed the muffler. The exhaust will be 7 feet of Surflex exhaust hose. I think that will quiet it enough. Not sure what I am going to do with the inside of the hull for a finish. However I am not going to do anything untill I am sure I don't need to do any more fiberglass work.

More pics
I rolled it outside today. Arggggggg.....The sun brought out a lot of things I hadn't seen.
Whoever did the glasswork on the bulkheads was better at creating runs and drips than spreading resin. It's going to be a ton of work to get the cosmetics done. Oh at least I will have something to do after it is in the water.

It even runs
The silver thing by the timer is the fuel pump. It's from a Briggs and Stratton and runs off crankcase pressure fluctuations.
Once it starts pumping water out the exhaust it is nice and quiet.

I think it's done. That is done enough to go in the water.
These will be the last pics on this thread. It's too big anyway. I will create a new one for when it's in the water.

For all those under 40 in Aussie thats a draft of 280 mm with a beam of 1.3 metres.
Thanks Ernie |
