Re: Inboard outboard air cooled engine

I'm hopeing he attaches it to the metal , where the metal attaches to the wood will soak up some vibration with smaller screws. I feel the larger lag bolts through the engine base into the wood may cause the wood to crack.due to the vibration.

I still say the wood, but maybe thru bolts, nuts, & lock washers, But either way, I think he needs to button the coupling all up, so that everytng is lined up on center, then mark it out, and, or, drill it out for mounting the motor, so it all stays true.

Re: Inboard outboard air cooled engine

Here's what I came up with. Two angle braces bolted to the lower unit, then two wood blocks attached on either end , then the wood blocks fastened to each side of the box. The angle braces look like they sit on the floor but are about an inch or so above it! If this set up will work without fiberating my arm off while steering, I don't beleive it will fall apart, it is sold as a rock, plus it's fastened to the hull under the boat! Hoping the rubber coupling will take care of viberation up top! I still need to install the plywood pads on the bolts you see sticking up, then I'll be ready to disasemble everything and seal it all up, as I do the final install! Here's a picture of my progress tonight! Oh yeah! Got a sore thumb, broke a small drill bit drilling the angle braces tonight, drove the bit right in the end of my thumb. I saw stars over that one for awhile!:redface:

Re: Inboard outboard air cooled engine

Hey, It's coming along good, looking better all the time! Sorry you got hurt! been there, done that, I'm familiar with those stars,,, Yrs ago I was wood shingling my house, and using hard spring steel like nails, the hammer used to slip off easily, after going around the house some, I must have hit my thumb countless times, until it was almost a bloody stump,,, then I hit hard one last time, and I saw stars, it dropped me to my knees, I felt sick, and had trouble breathing, I almost passed out, I made it inside, and under the cold water faucet for finally some relief, needless to say I was done for the day.

Re: Inboard outboard air cooled engine

The unit looks real good. I think your on to a great creation. Keep it up. Speaking of hammers, nails & such , years ago I was building a wood shed. As I was putting up the last wall I was standing inside leaning out between the studs drivind a 4" spike toe nailing into the plate. As I was swinging the hammer the claw caught on the next stud. And with a mighty swing I hit myself in the back of the head. I did not see your stars all I remember is black. When I woke up hanging out of the wall it took some time to get to my feet. And when I did I threw up. It was a week before I felt well enough to finish the shed. :redface:

Re: Inboard outboard air cooled engine

I took a big drink of pepsi and layed down on the garage floor for about ten minutes, I learned from the doctor at the doctor's office that pepsi would calm the sick feeling the time I got the fingers on my left hand mashed! Of course I closed the garage door so the neighbors wouldn't think I had lost it laying sprawled out on the cold garage floor, which helped to!

Re: Inboard outboard air cooled engine

Wow, some serious hurt you guys! I certainly wouldn't want to be in your shoes, but chill out, and do what you gotta do to recover. Stuff happens!

Re: Inboard outboard air cooled engine

Motor mount holes are drilled and the shafts aligned. Now it's time to disasemble everything and give it a last inspection and then put it all back together for the final time, sealing the unit in the hull as I go to prevent leaks.

After that it will be time to start on the shifter that I plan to use, some sort of stick type I think right now!

Here are some pictures of past and present!

Re: Inboard outboard air cooled engine

Wow! You're really goin to town on that! progress in leaps, & bounds, good for you, it must be a lot of work, but I enjoy seeing it coming along well.

Thanks to you and LD and others it's been a lot of fun throwing idea's around and getting it to this point. Mounting the lower unit stumped me for about a week, thought about the angle bracket and that solved that problem! I'm about half way now, alot futher ahead at this point than I thought I would be!

Have you seen "Scaaty," I was hoping he would get in on this project!

Oh! I say! Well Done OL Chap! Now that I see all the peices . Putting it together in one unit would have been next to impossible. With out the benifit of a machine shop.

Re: Inboard outboard air cooled engine

Machine work would have been out of my price range! I think I'm about $60 into it now, and am hoping to complete the project for around $125, will have to see how it goes!

Got lucky on the oil drain it comes out the side and not the bottom.

Yeh! Looks like you can put a short pipe on to come out over the edge to a pan. Less spillage. Looking good. How long before first start up ? You won't need water to test your alignment. Heh Heh!

Her's what I came up with for the oil draine. Simple and neat. Will make changing the oil a breeze!
Start up next 30 days! Maybe!

Got lucky on taking the muffler off though, thought for sure the bolts would ring off, but came right out, no problem! Looks like 1 1/4 in. pipe will thread right in. Right now I plan to use a short shot of pipe straight out of the exhausht port, a 90 degree elbow, a straight shot of pipe to the stern, a 90 degree elbow, another straight shot of pipe thru the top of the stern and then the muffler on the outside. I will make the hole thru the top of the stern large enough so that I won't have to worry about the stern lighting up!

I was thinking about the launch date, still an awful lot to do, don't want to get in to big a hurry and do things the wrong way. Maybe! March or April, getting cold here now! I'm a fair weather sailor these days!

Yeh! or you could angle your 1st 90 to just clear the top of stern ,then more pipe use a 45 or a 33 nother pipe over stern with a support then muff. No more holes and no heat problem.

That was my first design, I don't really like the idea of putting a hole thru the stern, but I thought it over and I could see myself reaching back there and layng my hand on that branding iron. I'd have to work pretty hard to get my hand on it with the thru the hull design because it will be hidden under the air cleaner! I'm thinking a hole 2 1/2 in. with the 1 1/4 in. pipe should be enough clearance, what do you think? Another words will 3/4 in. clearance all around be enough?

Ok! looking good, By the way, is that exhust port threaded for pipe? and is it 1'' (I.P.S.) iron pipe size, = 1 1/4" O.D.?,,, Or 1 1/4" IPS = 1 1/2" O.D.? I'm betting it's 1" IPS. I would go over the transom myself, why mess up the integrity of it? I doubt you'll be reaching back there much, plus, You're gonna wrap the pipe anyway, No? besides it will be cooler that far away from the motor. Also, I'd use some Galvanized iron pipe so it doesn't rust, and it looks better.

By the way, whereabouts do you live?

Re: Inboard outboard air cooled engine

Come out far enough before you 90, keep the pipe about 5" from air cleaner and engine.You want to dissapate the heat not burn air cleaner or heat the block up. Later after test you can build a shield out of lite expanded metal. Heh Heh we will keep you working on it for years if you follow all of this sage advice.

Re: Inboard outboard air cooled engine

IMO, the long pipe alone should dissipate the heat some, it's not like the baffling of the muffler right up against the block (causing it to) or holding the heat in, and reverberating the noise inside. In fact, I think I would at least try it without a muffler on the end
1) So it's not as restrictive, with less heat build up
2) The pipe itself will change the tone, muffle it some, & take away a lot of the roar, (more like a pop, popping sound) it may not even be that loud as to require a muffler on the end,
But if it does, remember that the muffler will be of the straight thru type, again drawing away a lot of the heat, and restriction.

North Carolina!

It is threaded! 1 1/4" O.D. No wrap, not in the budget! Galvanized pipe will be used.
