Lift the Perkins 4236 on a Mango

Hi Amelowners,

we intend to change the engine mountings on our Perkins 4236 and did order the rubber parts from Amel. Now we need to lift the engine to get the old ones out and the new rubber underneath. Has anyone of you an idea whats the most pleasant way to lift the engine? We thought to use a pulley or something similar. Would be really great if anyone of you has some tips for us.

Thank you in advance.

Best,

HI there
When we dis this on our Maramu we just put a i-Beam across the (padded) cockpit coaming and then used a lifting tackle off that 
It worked well and was very simple 
I presume the same would apply for the Mango but i'm not sure if you have the same lifting cockpit floor engine access?
All the best

We did it already on our Maramu, lifting off & replacing engine afloat.
A stout piece of timber on top of engine, resting on cockpit side benches & main sheet did the trick once the engine was disconnected from its holding bolts fastenings to the support frame ...
This was the hard part 
- one nut on rear aft stb side gave poor access with the famous 1/8th of a turn with open wrench already grinded to enter space betwen batteries compartment & engine base; guess you can expect one of those
- engine base & mountings stuck by grease, & salt & whatever when trying to lift first, high resistance countered using crowbar & wooden block & wedges & sledgehammer (cautious when beating).
- removal of shaft was easy enough (4 bolts & nuts 10mm) then moved by hand; reverse to connect checking alignement respected when reinstating (clock markings on flange helped)
all makes an interesting day of work, & good Opportunity to clean Bottom & repair paint work. Satisfaction when completed - do not forget to check tightening of bolts on support frame after a while running - they come loose unless you Added loctite on threads.

Meanwhile fair winds & Following seas

When we removed my old Perkins they placed a beam across the boat and used a a manual chain hoist. It worked very  well.

Frederic,

    I changed the original Amel mounts on my 1987 Maramu with a 4-154 Perkins this past June.   I attached the main haylard, the mizzen staysail halyard and a backup line looped over the mizzen spreaders to the end of the main boom and then used my HD Harken main sheet to do the actual lifting between the boom and the engine, running the tail to a winch on the mizzen mast.  A single haylard in theory could easily support the engine but it only takes a small amount of time to add more support and you do not want to drop an engine.  I also added a safety line for the lift between the boom and the engine which I adjusted at regular intervals going up and down.   A chain hoist if you have one is a great tool to use as was suggested.  The engine lifted easily and was no problem to reposition on my boat.  I did not need to remove the engine hatch or anything else major, great design work by Amel for this eventuality.  I also replaced all of the isolation dampers in the Vetus coupling.  The driveline is super smooth now, no vibration at all.  Despite this I checked the alignment again at 50 hours and as suspected the engine had settled a bit on the new mounts which is normal based on the many other mounts I have changed.  Best of luck with your project.

I recently swapped out my Perkins Prima M80T for a Beta Marine 85.  I used the following engine support bar.

It spans perfectly across the seats of a Super Maramu.

As far as the Beta goes, Isolated ground, no computer, super quiet, no vibration, very fuel efficient (1,800rpm = 7.2 knts), and plenty of torque.  We are extremely happy with it after running for 150 hours this summer so far.

Thanks, Dan

Thank you very much to all for the fast responses. The big nuts of the engine mounting are already open, so this part shouldn't be a problem anymore. I think we will try the timber solution to prevent any damage of the boom.
Hopefully everythink works out well.
