Re: Inboard outboard air cooled engine

I'm very impressed - you are indeed a craftsman. Can't remember where you are located -- do we have to wait til a thaw to see this thing run or do you have year-round access to the wet stuff?

Outer Banks of North Carolina. I'm about ten minutes from where I launch my boat. The pictures are of the area where I fish.

Hopefully I'll test things out with the "Shaker" in the next thirty days, if I catch a nice day like today and it's not too cold. That will give me chance to fine tune things and make any changes.

If the "Shaker" turns out to be a "fast boat" I may need to display a number on it! If that's the case maybe I'll change the name to "SHAKER 12" seeing the boat is 12 foot long.

Re: Inboard outboard air cooled engine

Thank you kindly!

Sat in the boat today for the first time! Everything works great, tiller is smooth, shift works good, throttle and key easy to reach, was able to keep one hand on the tiller at all times while going through the different task that I will need to be able to perform while docking etc. Pretty happy with the way it all has turned out so far.

Still some things to do like the battery, still haven't made it to the wiring yet, still have to change the crankshaft seal. Waiting on the resin and paints to dry right now.

Well You've done a Fine Job so far! I've been admiring this all from a distance, & and encouraging you on, as I'm sure the other posters here have been also. You must be close to being done, and where you live might have decent weather on occasion to test it out. At least you have a fine design to begin with, in case any issues should appear, you will learn from them, and be able to work them out as needed. Wish I could be there for the maiden voyage. This project has been interesting, & fascinating, keeping us all occupied during this dull winter season.

It has been a lot of fun, shouldn't be long now will be able to give it a try. Who knows maybe some day you'll be down this way and will be able to give it go!

Working on the wiring now, once I decide how I want to place it in the boat I'll fasten down the motor and check everything over good and see if there's any other little things I want to add while waiting on the weather.

There is one other thing that I've been thinking on, I've got an electric wench from an old boat trailer, thinking about mounting that in the back of my truck and doing away with the old hand crank!

Re: Inboard outboard air cooled engine

Wired the engine tonight. The things that are different from the wiring shown is that I moved the neg battery wire to the base of the engine and grounded it to the engine block and added a ground wire from the mounting point of the stater selonoid to the base of the engine block. The green wires that are mounted to the frame were moved and mounted to the starter selonoid mounting location also. Will give it a test fire tomorrow night see how it runs.

Lookin Good! By the way, my stepson lives in south Charlotte (Steelcreek area), we usually visit at least once a year, but I imagine thats still quite a distance from you, just not sure exactly how much? I really would like to check out the "Shaker" up close, if I was nearby sometime, thanks,,, but who knows when? Anxious, & Curious, to hear how the driveway test works out, whenever you get to it.

Hot damn! looks real good. How hard is it to remove engine ? The reason I ask is that your selonoid is under the engine is it not? If it quit on you at some time, you could short between poles and still start engine. With it under the engine that would be difficult.. But I guess you could carry a batt. cable and go direct to starter and leave pos. cable off selonoid.

The selonoid is in the open enough that I can get to it if I need to, beleive me I was thinking ahead on that one! A phillips screw driver, a half inch wrench, a pair of channel locks and the motors out in about ten minutes.
Make that 30 minutes I forgot I was using some power tools, on the water it wood most likely be hand tools!

O.K. Great. Come on! come on !come on! Start it up. I can't wait. Everything I got two of . I'm keeping crossed along with my fingers. GOOD LUCK GUY!

Re: Inboard outboard air cooled engine

Fired up the "SHAKER" tonight everything works good, but the exhaust thru the stern gets plenty hot so I drilled the top full of holes, if that doesn't keep it cool I'll have to come up with something else. There's a little 1/4 inch hole drilled in the back of the muffler from the factory, aiming right at the stern where it gets hot, why would there be a hole in a new muffler, can I plug it? There is some viberation, but it's smooth if that makes since. Will probably need a throw cushion to sit on. Overall I'm pretty happy!

Here's a little clip of it running, sorry for the poor lighting. Batteries in the camera were low and didn't have anymore that's why so short on the video.

Sorry! Every attempt to upload the video has failed, don't know if it's because I'm doing something wrong or some other reason, my first try at it so it's probably me!

Maxum I thought you were gonna get the straight thru lawnmower muffler? I think it would run cooler, the one you have is a perforated can type muffler that has the exhaust reverberating inside, it would tend to get hotter, hold the heat, and with all the holes in it, it's really not quieter. Here check this out: Shoot maybe you could even put 2 of these on there if need be, for "low restriction" http://www.smallenginewarehouse.com...+Thread+fits+many+Briggs+and+Tecumseh+engines

I agree. He should get the longer narrow type which as you say is straight through. And yes ! he can plug that hole. And I still think he should use a piece of heavy screen or expanded metal instead of a cover with holes drilled in it to keep transom cooler. Also cover the ex. pipe with it to protect from burns.

Re: Inboard outboard air cooled engine

Yep, get a straight through...the perforated to restrictive

Yeah! That's the type muffler I was looking for, everybody around here was out I guess, all I could find was the eight dollar one that I have, don't like it much. Looked the other day and again today no one has it! Mowing season will be in again soon then I'll be able to pick one up. Could order one but I like to see what I'm getting.

Re: Inboard outboard air cooled engine

Just a little input on that muffler that Mikdee posted a link to. I believe that is the same type of muffler I used on a Snapper riding lawn mower and it didn't hold up well at all. I finally got the muffler tightened down where it wouldn't come loose but the next thing I know the muffler came off/broke loose off of the pipe, it must of broke the weld. It did not hold up to the pressure.

Cheap muffler, just be ware.

 

[wildmaninal]

Re: Inboard outboard air cooled engine

Oh forgot to mention that it rust really easy also, I still have the broken muffler to prove it, I forgot to throw it in the scrap pile that I hauled off. I have another one just like it installed on the mower but I don't expect it to last long plus the mower has problms that I am going to half to fix, I already had the spare muffler on hand (heck they were free basically when I got them), believe me I wouldn't buy another one.

Re: Inboard outboard air cooled engine

Got a question! Has this project inspired anyone to build there own inboard/outboard air cooled boat?

Here's one other thing I left out on the build. These are pictures of the way I ran the gas line, I'm undecided if it's the safest way or if it may boil the fuel but it worked well on the test run in the garage. Any opinions?

Wild, 1st of all you're supposed to use a lock ring on the threads to hold the muffler on (this is the same lock ring electrical piping uses to fasten to an electrical box) it is like a small spanner ring with a std. pipe thread, and usually can be found in any hardware store that has electrical supplies.

I also suggested maybe using 2 of these muffler, in place of 1, to take the load, & wear & tear off 1, they appear reasonably priced. You can add an I.P.S. (Iron Pipe Size) galvanized Tee, plus 2 Galv I.P.S. Elbows, then just screw them into this.

The gas line looks fine, it makes no physical contact with the motor anywhere, besides,,, that, and the exhuast system will have air circulating around them at all times when in use to help keep them cool, unless you plan on covering the motor in the future? Also, I'd say you found some great creative uses for eyebolts on this project.
