Cherubini Hunter 33 yanmar remove

In "Hunter Owner's Mods" under H37C you can see my engine replacement. It includes, I think, my method of pulling the old and heavy 2QM20. Basically I welded a 'C' bracket to go around the companionway so that I could lift it from the center of balance.

Left that part out I guess. I bought the Yanmar from my marina. They used the rack forklift to lift out the old one, drop in the new one. It was part of the deal.

I think you can just run a bar or beam across the hatch with a chain and come along hanging down to the motor. That will get it up to the cockpit. What you do from there...

I have done this several times with different boats and engines. I usually use the mainsheet if it is mounted above the bridge deck like the original 33's and 37's. I make sure I have a really good topping lift secured tightly and lash the boom off so it can't swing back and forth. If worried about the boom being able to take the weight, mount the haliard or topping lift with a strop right next to or above the lifting tackle.
As per Ed, the best way is to use the marina forklift.
I would doubt the 2QM20 would be 600 lbs. and definitely not the 15hp.

I did this dec' 2010, I first put a scrap 4x4 across the companionway and attached a 1/4 ton mini chain fall bought very cheaply at harbor freight (this is recommended as a large chain fall is a PITA in such small spaces) shackle the engine lift point on the head and transmission. on the way out i had 2 friends control the forward swing as i lifted the engine off the mounts, on the way back in i put a block and tackle horizontally aft from the rear lift point and wrapped a line around the fiberglass bulkhead just forward of the steering quadrant this made the whole operation a lot more controlled i had removed the fuel tank and the shelf it was on because they were both past their prime which isn't a bad idea even if you just clean it well. once the engine was moved directly under the companionway on a scrap piece of 3/4" ply it was re-rigged to the boom with a very strong lifting strap AROUND the boom as to carry all the vertical strain and the boom was used just for leverage and to swing sideways the main halyard was attached to the top of this strap and used to provide the lifting force, once the engine is high enough you can pull it aft sliding farther out on the boom until your clear of the cabin trunk, i then swung the whole rig 90 degrees and lowered onto the dock and rigged a 8' 4x4 to be put over the shoulders of myself and 3 very helpful friends and carried the engine up a very long steep set of stairs and put into a pickup this engine is not even close to 600 lbs. although halfway up the stairs it felt like it. in retrospect i would have removed everything from the main block to decrease weight but also so that it is smaller and without "fragile" pieces that can't be manhandled into position, I'm sorry if that was a bit rambling feel free to ask for any clarification, also i have to original shop manual (necessary) on pdf if you want it.

Lots of overthinking going on. If memory serves, (probably not) 2GM was about 250#, 3GM30F about 300#

Do not use the boom. Use the halyard from top of mast and a line from aft end of boom just to control position. My mast was down so I used a build-up of 2 X 4's with a trailer winch bolted on, cable coming down the center. The wood on the hatch slides allows easy movement fore and aft.

Pulling the 2 GM out I separated all removables and took them out one by one, reducing weight to haul up and out. Alternator, trans, water pump. The 3GM was on the floor inside so I just hooked to it, had a friend who happened to show up crank as I guided the engine. (How I got the 3GM on the floor inside is a nuch longer, much more interesting tale.) Dropped it in place three times. Once to see beds were too low, again to mark for holes to drill on the new raised beds, and third time for keeps. Piece of cake. Do not lean on engine while checking alignment.

Do I need to mention that wood cabinetry was unscrewed and set aside, providing a big open work space?

no i put a folded old towel on the front of the companionway (trim that companionway stair brackets are on) and allowed the cable to make the turn aft. you can just guide is forward as it slips off of the engine mounts, sorry i just looked back and saw how it appears that way from those angles

Careful with that weight thing. The QM engines are signigicantly heavier than the GMs or anything that followed. If you can't find the number online then maybe a call to Mack Boring or Torreson.

P.S. - found this: http://www.marinshopen.se/Motorer/OmMotorer/Yanmar/Fastställårsmodell/tabid/367/Default.aspx .
2GM = 100 kg or 220 lbs.
2QM = 190 or 220 kg, 418 or 485 lbs. Without the transmission.

Redbeard33 · Feb 2, 2012

i just checked my manual, its 145kg or 320lb dry weight, unless some of the 33's came with 20hp, mine is a 1980 and came with a 2QM15

Interesting since the 15 and 20 are identical engines.

Replaced the engine last year. The engine installers gave me this tip. It may work for you. After removing the engine box and side bulkhead panel, place a 2X6 under the engine as a lever. You can stand on the end of the plank and lever up the engine out of its bed. Then it is an (fairly) easy matter to slide the engine down the plank to the galley sink cabinet. I did this myself without assistance, but another hand is a good idea. Then I waited for the engine installers. They hoisted the engine up and out. We used the club's boat hoist. The other methods listed here will work also. The task moves quickly once you get started.

I searched for info on this but did not find anything.

Have any of you Cherubini Hunter 33 owners ever removed the yanmar to have it worked on?

If so, what was the method you used to get it out of the boat?

I have sat in the boat and thought about it and I assume I will have to somehow manage to pull it forward enough to get a block and tackle on the boom attached to the motor. I think it weighs around 600 lbs, is that too much for the boom to handle (seems like a lot of weight to me)?

I have a 33 with the Yanmar 2gm and I removed, worked on and re-installed it. I just used a forearm curl and pulled it out with one hand. Did a modified shot put toss to get it on the dock... OK OK...we used the main halyard without any problem at all.
