Lifting my engine out with the boom

[BlackHeron]

Don't pull with the winches. Use a chainfall for lifting. it's the proper tool. The halyard is sharing the load a little with the topping lift a tiny bit too. Use s nylon lifting strap to position the halyard at the right location with perhaps a scrap if old carpet to protect the extrusion. Hang the chainfall from the strap. Go buy some cheap 3/8" galvanized bow shackles with a safe working load of 1 ton to hook averything together, don't be tempted to use stainless hardware from the boat. It isn't up to the task and even if it doesn't fail catastrophically it may get bent/twisted/ruined and never be the same.

Make sure the boom is high enough to clear the cockpit combing or whatever is in the way.

We lifted to a plywood pad protecting the cockpit bench, then re-positioned the boom and the lifting point after setting it down to better suit the trip over the side. Trying to lift the boom under load may be unwise.

What could go wrong that a couple thousand dollars could not repair. I always find that major projects like this are best performed on the hard -reduces the degree of difficulty, and risk, by 50%

i did that until m y mainboom showed signs of rot in middle..then we used 4 strong mexican fishermen. that worked quite well...from formosa into panga without splash or issues...then back again.. easy peasy.
yes i have removed and replaced engine a 3 times or 4.

-Supporting at the lift point is necessary.
-You need a lot of room over the companionway for the sling and the engine. 5ft+ vertical?
-Or fab a spreader bar to avoid the sling vertical space.
-You'll have to angle the boom up pretty far.
-Not sure how you get it over the side once it's lifted. Put it in the cockpit and rerig somehow?

Frankly, I'd spend the money to have the yard crane lift it readily.

BTW: 2 strong guys lifted my 3GM30 block out of the catamaran once it was stripped of excess weight, including the head, starter, manifold etc. Your Mitsubishi is probably heaver but...?

Thanks for all the experience! I'm all prepared and will do it next weekend! I'll post successful results hopefully!!

I've installed a motor whilst on the hard, and now one whilst at a floating dock and IMO, the install at the floating dock was much easier. No climbing up and down ladders, no dealing with a crane driver and dogman while trying to guide an engine with mm clearances down into the cabin and the ability to align the engine at the point of installation with the boat sitting true in the water. The only hassle is, of course, that the prop shaft can't be swapped although I'm sure someone, somewhere has also done this while floating.

Oh this is so true. I didn’t breathe for most of the process either.

For what it's worth, if you are concerned with the weight then you can always remove the gearbox prior to removal and refit after reinstall.

I did this when removing the old engine. The Velvet drive weighed a bit north of 70 kg.

But putting the Beta in I discovered that the new TMC60 only weighed in at 14kg. Hardly worth removing, though I did because it all counts in the end.

I just lifted my Universal M 25, 235lbs, with the main halyard. With the help of two friends holding tags lines, the engine was guided out through the cabin hatch area and over the side. I used a second halyard as a back up and used the deck winches.
Don't rely on the spiced eyes on the halyards, use a bowline knots.

I did this on my 30-foot boat with the old 500+ pound 2-cylinder diesel. I used multiple halyards- one at the end (where we strapped the come-along) and one in the middle of the boom to prevent any bending of the boom. Definitely check the rivets/however your cleats for the halyards are attached- we lost a cleat at one point, which could have ended disastrously. I'd also recommend something to protect your boom from your come-along- we used an older rubber water bag, just anything to prevent scrapes

[sailorladd]

I did, very easily and it was also a 3 cylinder diesel....

I just re powered using the same method of using the halyard to take the weight. Adjusting the pick up spot with a traveling block controlled with the vang. No real strain on the boom controlled the swing with the main sheet.

Hire a Hiab on truck. Cheap and risk free.

I recently removed 3 cyl Yanmar during electric conversion project. I used main halyard to support boom at location where I strapped chain fall. Rigged a double block below to control engine fore and aft then lifted her right up and out onto cockpit floor.

Fortunately from there could use the jib crane on the dock to swing it over to the dock but had no issues using boom to lift it out of cabin.
