Re: Lifting an engine using a beam on cockpit seats

Likewise we did not use the seats but the coaming around the cockpit where winches are located

Re: Lifting an engine using a beam on cockpit seats
G’day Mark, can I please ask how many hours had your motor done and what year launched? This is to give me an indication on what perhaps to expect

Re: Lifting an engine using a beam on cockpit seats
Mark McGovern
I just replaced my engine mounts and the goddamn pain-in-the-ass bloody Vetus coupling a few weeks ago so I have some recent experience with this topic. I considered using the cockpit coamings as the base for my lifting beam as they are flat and obviously strong. However, it would have increased the span of the beam significantly so instead I used a 2 x 6 inch beam placed across the seats to lift the engine. I did make crossmembers for each side of the beam to spread the load out a bit more across the seat. Here are some pics of the beam and crossmembers:
The dry weight of a Yanmar 4JH3-HTE is only about 500lbs. I removed both alternators, intercooler and exhaust elbow before lifting it so even with all the fluids added in, it likely weighed less than that so you are looking at maybe 250 lbs per side. Spread that load over approximately 50 square inches and that is only 5psi of force so I was not too concerned. The first time I lifted the engine completely I barely lifted it off the frame and looked and listened for any sign of cracking or deflecting and did not see any. I am certainly NOT saying that doing something like this can't cause problems but I can say that in my case with my setup and preparation of the engine (removing some of the weight), that it did not. I still have the whole lifting setup on the boat so if anyone in the Chesapeake Bay area wants to borrow it in the next year or so, shoot me an email and you are welcome to. I will need it back as I intend to re-align the engine after a 100 hours or so assuming that the mounts will settle a bit. -- Mark McGovern SM #440 Cara Deale, MD USA

Re: Lift the Perkins 4236 on a Mango
Dan Wilcox
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 SV Feierabend SM#86

Frederic, I changed the original Amel mounts on my 1987 Maramu with a 4-154 Perkins this past June.

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.

Re: Lifting an engine using a beam on cockpit seats
Patrick McAneny
Bill, I agree and would not put that kind of weigh on the seats. I placed a 4x4 across the cockpit resting on the coaming next to the winches,I further spread the load with a 2x6 under it along with padding . I used a come along to provide lift and positioned it slightly aft of the lifting point on the engine ,so it was inclined to move aft away from the trans, moved the lifting point slightly forward to move the engine forward to reinstall.

I saw a SM with delaminated fiberglass on the cockpit seat exactly where a beam you describe would rest on the seat. I never connected the seat delamination to an engine lift, which I believe occurred on that SM. NOW, I DO.
I doubt the seat is designed to take significant weight. I would CAUTION this practice.

Re: Bow Thruster Service
JL Mertz, CottonBay: Yes, it should be "easy." There are 4 Allen head bolts on most SN & SMs, but in later model SMs, 2 bolts. It is always easy if the bow thruster is serviced correctly, with seal replacement when needed, and never left DOWN while sailing. But, if you don't follow the above, you'll be lucky if it's easy.

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

Re: Lift the Perkins 4236 on a Mango
christian alby
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 chrsitian alby - Désirade VIII - Maramu 116 - now in Canet Roussillon

Lift the Perkins 4236 on a Mango
Frederic F
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, Family Fießer Mango #14

Hello, if the 4 bolts that hold the bow thruster are out it should be easy, Drive the bow thruster simply go down, then from the outside of the boat rotate the bow thruster, possibly by a movement rotation back and forth. Always sweet ... JL Mertz CottonBay
