I wasn't sure where to post this but I figured those here would best appreciate this.
Yesterday was definitely one of the times where I wished I owned a camera phone.
A buddy and I decided to haul my 14' tinny down to the creek today to do some last minute crabbing and fishing before the storm hits, that idea turned out to be a mistake, there were probably 100 people in line trying to pull their boats out before the storm. Not wanted to waist the trip, I drove up stream a bit to a small dirt landing, hand lauched the boat and went about fishing for several hours. After a bit I decided to head up stream and try for some crabs, a ways upstream we run across and old man in an old, raggedy Renken trihull, with an OMC I/O set up. He was tossing the anchor and retreiving rope.
I circled back and asked if I could help, he went on to explain that his motor died and he couldn't get it started. He had been out all morning and was only 1/4 of the way back to the ramp.
I offered to help and he said I was welcome to try but he gave up hours ago.
To my surprise, the dog box was made of T111 siding, and about 3' taller than normal. He proceeded to show me how the top of the box folds back on hinges to expose the engine. (There were no gauges or controls on the dash other than several toggle switches. The boat had bench seats installed over a plain plywood deck. The seats were screwed in from each side right through the glass hull. He said he didn't have a starter, and when I flipped the home made cover back I saw why...
The original inline four cylinder motor was gutted, all but the oil pan and block were gone. On top of the block where the cylinder head used to reside was a steel plate, with a cast iron Wisconsin cement mixer motor bolted on top of the original engine. There was what looked like a motorcycle chain going from the air cooled engine up top down to a sprocket welded to the original crankshaft. The oil pan was filled to the edge, and he made a sheet metal funnel to keep the oil in the pan as the chain turned. The added on motor has no recoil, only a rope sheave. I gave it a few pulls and it didn't feel healthy inside.
I told the guy something broke inside, and that I'd try to tow him to the dock. My 14' Sears tinny with a 6hp Johnson handled that task just fine.
Getting him back on his trailer was another ordeal, his trailer was way too small, the frame extended with huge 4x6 bunks with no carpet. It had no winch, he said he normally just drives on the trailer, ties off the boat and 'Seats' the boat by slamming on the brakes a few times once he's on pavement. My buddy, myself, and two others that I recruited by embarrassment at the ramp used a rope and some leverage to get the boat up the trailer enough to get it off the ramp.
By the time this whole ordeal was done, we figured we'd best head back to the other ramp and get on home before dark. I ended up searching for the ramp in the dark with a spot light and loading in pitch black night anyhow. At least my boat is light and easy to load.
I didn't get to stick around and marvel at his contraption on land, but he said he never goes farther than that creek, and I suppose it moves the boat well enough for him, but at his age, I figured he's more than taking a few risks with a rig like that.
The boat had to be 16' or so, I can't imagine that motor moving that boat very well.
I'd also probably never have even thought about a rig like that. What was worse yet was all the milk jug bailing buckets all about the boat, my guess is that it has more than a few leaks as well.

Before I had drafted the two standerby's to help load his boat, his suggested was to use his truck to load the boat, "He said he had done it before". His plan was to unhook the boat trailer, let the tongue jack, (with no wheel), dig into the ramp, as he pulled the boat onto the trailer with his truck. Then all he had to do was reconnect the trailer and be on his way. Not wanting any more entertainment we just manhandled the boat onto his trailer and got out of there.

It just goes to show when you think you've seen everything, something like this pops up. I'm not sure how he'd have reacted if I did have a camera, he may not have taken too kindly to someone snapping pics of his boat or his custom work. He reminded me of an old moonshiner type from the hills. I'm sure he was glad for the help though, although he never said much the whole time. He just looked at me odd when I refused his $5 bill, I figured by the look of his boat he needed it more than me.

As i' reached the part about the motor cycle chain , it reminded me of the Wacky Races' Arkansas Chug a Lug . lol,.....this only goes to show that boating is a lot more fun than mixing cement . :facepalm:

Re: Ingenious I/O fix....

... and now that the cement mixer motor has died there will be a 2 stroke weedeater motor mounted to the top of the cement mixer the next time you see this guy.:rolleyes:

Re: Ingenious I/O fix....

a cast iron Wisconsin cement mixer motor

A high school bud put one of these motors on an extensively-modified gocart chassis. He, like the "old man", probably thought it was a good idea at the time and lived to laugh about it.

Re: Ingenious I/O fix....

I agree, tough to figure out where this thread belongs. Non-repair I/O, OMC, SHTs, Trailer, any other fits? Wow!! I actually like backyard hack engineering, although this boat sounds like anything but safe, I have to applaud the guy for keeping her going.

Re: Ingenious I/O fix....

I guess its fair to give him credit for his redneck engineering skils, especially since it didn't get him hurt or killed I guess.
I think though if I were to design something like that the rusty hulk of iron, or old engine block would have to go. The shear dead weight alone couldn't be helping the under power situation much. Granted there's no way that motor would ever get that tub on plane either way.
Those back creeks run hard on an outgoing tide, if he hadn't of gotten lucky and had someone come along, no doubt he'd have had to anchor and wait for the next slack tide real soon, or end up getting flushed out into the bay, if he made it past all the buoys and various other hazards.

I'd also have picked a motor with electric start, or at least a recoil starter, wrapping a rope around a pulley everytime you need the motor is for the birds, especially when it don't start on the first pull.
Those old motors were low RPM engines too, I can't imagine that thing would go much faster than you could paddle it when it was running like that. I think he'd have been better off with a home made raft made from 55 gallon barrels than in that boat. It was the typical rotted gut old trihull you find listed all the time on CL for free. Besides the dead Chevy four cylinder, it probably had a ton of water weight in it as well.
My guess was that he had done the "dump the trailer and pull it on with the truck" trick a few times before.
By the look of the truck, maybe I should have looked under the hood to see if that too was repowered with some odd ball motor too.
The one thing that really stuck in my mind was his rod holders, it didn't really sink in right away but they were made from pieces of exhaust pipe screwed to the inside of the gunwales. They were rusted pretty bad. Being concerned about just getting done with the task as hand I didn't pay much attention but thinking back my look at those rusty rod holders, a boat trailer winch bolted to the right gunwale, and all those cut in half milk jugs all over the boat are what comes to mind. There was also saw cuts all over the hull, where he either discarded something he didn't like about the boat or cut away parts of the hull to save weight. None of which could have been very good for the hull itself, if any of that mattered in the condition that thing was in. With that in mind, having under 10hp was probably the one thing keeping it in one piece.

i'm getting mixed feelings about the old man . my 1st thought is to tell him how fkn stupid he is for putting his life in danger , yet i'm torn between that and wanting to buy him a brand new vessel , cause he probably never had enough money to pay the bills but wants/loves/needs to be out on the water .
as we bear down and get ready for Sandy , its a humbling experience , boater or not .

Don't we have a section called "stupid human tricks" -- :facepalm:

I guess that's a little harsh; the guy just wanted out on the water - necessity is the mother of invention... :)

Re: Ingenious I/O fix....

An interesting tale.
He likely did not care if it went very fast.
He also probably had the old Wisconsin engine or got it somewhere cheap or free.
Given this was an old OMC, he would have needed to keep the block. It is a stringer and he needed the engine block with the engine mounts to support the smaller engine and resist the thrust of the engine. You would not be able to remove the old block and just leave the front of the intermediate housing loose.
An interesting solution to his problem. A bit rustic but if he did not need to go fast, it worked for him. Sort of a "rat rod" boat.

Re: Ingenious I/O fix....

That's not the first I've seen or heard of mounting an air cooled engine atop a dead inline motor before. A number of years ago I saw a home made tractor down in NC that was done the same way, they took the rear axle from a small truck, welded two round pipes to it about 18" apart to make the frame rails, then they used an old flat head four cylinder engine and a truck trans. They had actually cut the block down though, shortened the crank, and made a straight shaft out of the crank. The chain ran down through the rear most cylinder to a sprocket that was welded to the now straight crankshaft. They left only two cylinder holes and the front and rear bearings. The oil pan intact and sealed in the front. They then made a steel plate which covered the block and incorporated a chain guard and oil catch for the now splash lubed chain.
The motor was an unkown, I didn't recognize what it was. Something 1940's era or so.
The rear wheels were home made, they used tractor trailer rims and tires with chains, but made flat iron spoke centers for them to match the lug pattern on the axle. The front had one wheel, which looked salvaged from an old tractor.

I think if I were to really put my mind to making a big air cooled motor run an I/O drive, I'd probably weld up a mounting plate that incorporated both the mounts and the drive support needed, then work on attaching the air cooled crank to the outdrive. But I'm sure that old guy had none of the machine shop equipment or skills that I have at my disposal.

The neatest old home made power I've run into for a boat was a belt drive rig that used a 10hp Briggs stratton motor mounted to the floor of the boat at the stern, with a belt running up to a pulley on a shaft, atop the transom, with another pulley mounted on the other end of the same shaft, then another belt ran down to another shaft bolted to a pair of pillow blocks under the boat with an inboard prop on the end. I've got no idea how long the bearings in that shaft lasted underwater like that but when I saw it, the owner had just put it back on his trailer after a day on the water.
I've also seen a few boats with outboard lower units bolted through and sealed to the bottom of the hull, with vertical shaft lawn tractor engines connected to the drive shaft which protrudes through the hull inside. That set up actually worked quite well other than the obvious shallow water issues.

Re: Ingenious I/O fix....

I get a kick of out of ingenious solutions to problems sometimes. I probably would have put the guys boat in the "way cool" category (but for goodness sake don't take it out farther than you can swim man!), and left the trailer in the "fix that, bro" category. I like it when my kids come up with interesting rigs for different things they want to do ... and I think it encourages creative thinking and problem solving.

What a problem solver in another life he could be a CEO of some large corporation need more people to think outside of the
