A couple of years ago (almost to the day) I had a U joint bellows fail on me and only noticed it on the way to SD to go tuna fishing see post.

Well it took about 1 year and 10 months for the noise to really start. My transom bearing was beginning to really growl. Knowing that I want to change to diesel power in the near future, I wanted an at home option for plucking engines from my pretty tall in the driveway boat..

So I hatched this idea for an engine hoist frame. Being an electrician I used parts that were at hand.

Materials used

20 ft of 3" rigid conduit
30 ft of 2.5" rigid conduit
2 junk lighting brackets
2 6" scrap pieces of 2" rigid conduit
4 90 lb bags of concrete
4 3/8 x 2" bolts
a little bit of 20 mil. tape



First I cut out a 16 x 16 area in my driveway that worked with where I park the boat. I dug a hole with a post hole digger that was about 2' 6" deep in the center of the hole I cut in the driveway and one in the planter on the other side. Then I cut and threaded (2) 3" X 2' 6" pieces of pipe and taped them up for protection from corrosion.



I let the concrete harden then inserted (2) 10' sticks of 2.5" conduit into the 3" sleeves in the ground. I then installed the 2" scraps into the old lighting brackets and slide a 10 piece of 3" conduit on top. I then drilled hole through the threaded holes in the brackets into the pipe so I could use the bolts as pins to hold the horizontal in place. The lighting brackets were not my first choice but I wasn't able to find anything else that would work.






If I didn't have the brackets I would have had a welder attach some 3" to some angle iron instead. I also made 2 extenders out of the 2.5" conduit that are about 5' long and will enable me to get the engines above the rail and out of the boat. All that was left was to add a chain hoist that would handle the job.



I got the bell housing off and I'm taking it in to get the bearing pressed in there tomorrow. I also have a few other things to change.



I was trying to upload pics but its all fucked up for some reason.......


Okay figured it out

looks like you nailed it there Dean! Are you switching to diesels now or waiting? If diesels, what did you find for your rig?

No not yet David, can't quite afford that now but I'm staging for it. I'm just changing the bearing and putting it back together, replacing the port shift cable and both the bellows. I have a VP 41A on an engine stand in the garage waiting for its twin to show up on ebay or something.

Oh and if any BDrs in the area need a hoist feel free to PM me I'd be glad to let a fisherman in need use it.

Yeah, it's a tough time to afford a repower, especially going diesel. I'll keep my eyes open for a 41a for you as I'm always poking around ebay, craigslist, etc anyway. Shoot me your email addy and I'll email if I find something worthwhile.

Very nice. I should look into building a boat shed using the steel conduit. I need to get over 13' 6" height though.
Since I have more wood working tools, I went another route for my engine hoist.
Nice work your self there Jerry. If I didn't have the pipe threader I would have probably went that way.
However, I needed to be able to stow the thing when I'm done because I'm kinda cramped over here but it looks like you got a lot of room where your at. Thanks for the pics I like to see the ingenuity.

Keep an eye on Craing's List for a gantry. I got a Grainger 12' x 12' adjustable for $500.

Yeah a rolling gantry would be nice but this thing only cost me about $100 to make including the chain fall because most of the parts were free from work. Not to mention it will stow away in 3 pieces of pipe. All I have to do is patch the driveway and put plugs in the pipes and thats it.

Now I see what you do with all your extra $$$$$$$$$$$$$$!!!!!!!!!
Extra money? :rofl:

Pretty nice Dean............cleaver. Looks like it worked great. Brandon and I used Kapdan & his truck when we put our last engine in.

Don't have the room like you did to build our own. Dan shows up and takes it out..........then shows back up to puts it in and done.

Yours looks damn strong Jerry.........and all that room to work on your boat must be nice.

Curtis...........

Damn, thats a cool little boom truck. My wifey would have probably preferred it if I would have used Dan LOL

I do love tinkering though.

Yeah it's cheap until it drops the engine through the hull because the "pipe" didn't have any beam strength. "Conduit" is not pipe.

I'm cheap, but I do know the value of safety and good tools. I like the wheels thing. It's easier to move the gantry instead of the trailer.
The great thing is that it is also available for friends to borrow.

Well I'm a pretty cautious person I don't like taking chances with stuff like this and did a few tests on the rig before putting the full weight of the engine on it. The wall on the "conduit" is 1/4 thick and I realize that a tube is not as strong as a beam but this thing is overkill. With the full weight of the engine I was able to put my weight (about 210 lb) directly above the hoist and bounce with almost 0 deflection on the conduit. I also installed pins in the ends of it so even if it did give it would not fall through the deck it would only bend slightly.
I have bent thousands of sticks of conduit as an electrician and have a good feel for how it acts when your bend it. Without some kinda of impact like dropping the engine from 3 feet these loads will not be dangerous at all. The only reason I posted it was because I was a little surprised by the result. I though that this rig would be pretty unstable and a little precarious but would be safe. As it turns out it feels very stable and safe.

Also, if I did have a gantry there would be almost nowhere to move it to anyway. Like I said before if anyone want to use this they are welcome to come over and use it :)

Its very creepy hoisting over 1100 lbs 10' overhead. Hopefully overbuilt it enough to where I dont have a big block sitting on my lap in the bilge.
I live alone in the boonies. I probably wouldn't get help till the neighbors saw the buzzards flying into my bilge. It just wouldn't be right being taken out by a Merc marine engine. If Im going to do something stupid. It will be hitting the Cortez Bank on the wrong day :beerbang:
Funny...... All that room. 120' from the house to the boat on a steep drive. Seems like 30 trips a day working on the boat. :madfire::_hot_:

Not looking forward to using your hoist Dean but I'm glad you got it ;) :D. Going to start disconecting the motor this afternoon and hopefully will have it ready to pull out after tomorrow. Now I just need to win the lotto so I can get the parts to put the boat back together and try to salvage the end of the season.

Also KapDan was way cool and a great help when pulling my old motor out and dropping in the new power. His boom truck worked sweet.
