Re: Prop is spinning freely

On Aquarius we put her in Reverse to lock the shaft. Would Chris be able to do this? Or will it damage the transmission?

Hello Courtney,
Chris is still having a problem. Please write more about the procedure to correct the problem, I can't understand how to correct the problem. Is your comment is missing punctuation. "See where the plunger engages the brakes tape a quarter in this spot then all is well" Thanks! Ken Aquarius

Greetings to all, I was pretty unhappy with the lighting on my electrical panel, then discovered that most of the bulbs were not working. Thanks to previous emails from Arno regarding the repair. Here is more detail for those of you who would like to undertake this project.

Prop is spinning freely
Chris Likins
We have A54 #133. Today when sailing I noticed that the prop was spinning freely(in reverse) each time a wave would pass under us. It’s easy to see that the shaft brake is not engaging when the engine is in neutral or shut down. Referencing Bill Rouses book p.305, it reads that the hydraulic shaft OPENS the calipers when pressurized by the transmission. Currently the shaft is retracted into the piston at all times allowing the calipers to remain open. I understand that the calipers are supposed to spring shut on the disk when transmission pressure is lost on the shaft. I am a bit confused by this as there is no mechanical connection between the hydraulic shaft and the outer caliper. It seems like the calipers should close when the shaft is extended.. So my questions are
1. Can someone help explain this system in more detail? 2. What position should the shaft be in when pressurized and not pressurized? 3. Is it most likely a bad spring on the caliper? 4. Most importantly for now.. Is it ok to allow the prop to spin freely for the duration of the passage or would it be better on the shaft if we remain in forward gear. Thank you for the help!

Re: "Apple is examining a chemistry for the car battery called LFP, or lithium iron phosphate, for its car", that will bring the cost down for all of us
This will not likely have a trickle down effect for marine batteries anytime soon. The key differentiator for Apple is the "monocell" cell design, not the LFP chemistry. It's their way of trying to make up for the lower energy density of the LFP chemistry compared to other Lithium Ion chemistries like the NCA chemistry (lithium-nickel-cobalt-aluminum) that Tesla mainly uses. Tesla batteries are made from older, proven cylindrical cell design as well as a different NCA chemistry. Scott, your Victron batteries actually use prismatic LFP cells, not cylindrical cells: https://shop.pkys.com/Ever-wondered-what-is-inside-a-Victron-Lithium-Battery_b_167.html
Most other drop-in batteries like Battleborn do use cylindrical LFP cells to make their batteries. -- Mark McGovern SM #440 Cara Deale, MD USA

Re: Placement of Beta 60 in an Amel Maramu

Thank You Danny, Thank you for the explanation.
I am headed off to St Maarten for a new Yanmar mid January.
It is working perfectly and all the fluid samples are great. However with over 7,000 hours, I thought I would just replace it and never have to worry about something going bang on a passage . I was concerned about the possibility of breaking the oil pump, a wrist pin, or a connecting rod. Fair Winds Eric Kimberlite Amel Super Maramu #376

Hi Eric, it wasn't an hours issue. What caused its demise was the misunderstanding about rpm. It was maxing at 2800 rpm under load and the consensus on the forum was that there must be something wrong since under no load it would easily do 4000. Many of us tried to resolve what wasn't an issue. So when after about 2 years and 25000 sailing miles suddenly it would rev up to 3500 under load I thought it had resolved whatever was wrong. HOWEVER 2800rpm was the correct max under load and the ability to rev higher was caused by a jammed wastegate on the turbo. This is intended to open progressively to reduce the boost as revs increase. So with it jammed closed the boost pressure was excessive, hence the higher revs achieved. Not that I ran it at high revs a lot, but over several years the excess pressure damaged the rings and pistons and eventually I couldn't get better than 2200 rpm under load. I tried everything without success including quite a lot of Volvo specialist time. So one day, having had the engineer on board yet again I said b....it and ordered a new one. In retrospect it would have made more sense to do a recondition on the TMD22 since I had replaced most of the bolt ons. So you TMD owners. 2800 load rpm is correct and if you are getting more, check the waste gate. Happy New Year to you all Danny SM 299 Ocean Pearl

Hi. The Beta spunds a good option. However I repkced my tmd22 with volvo d275 and with 1300 hpurs up it is going well. Plus points. It has significantly more torque. Even with the propellor barnacle encrusted it pulls its standard 3000 rpm. Existing gearbox bolted on. Enging mount hole positioning was identical, fitted perfectly onto the egine bearers. All we had to do was make new forward end spacers to align the engine. Could not have been easier. It is significantly lighter than the tmd22 and this shows in the fore aft trim. It is a turbo. But no timing belt. It is a push rod engine, not ohc. I did not make up the spacer alignment tool for this job, nor for the engine mout repacement this year. No difficulties at all. Nil vibration.

I don't know how the cost could come down too much more... I got 600AH at 24V for $3600. The only thing I regret is not getting one more battery so I would have 900AH at 24V.
The price has come down so much that in Thailand it is more expensive to get AGM batteries than LiFePO4. Ken Aquarius SM262

The company making the above is closed for the Christmas holidays. The above will work in any SM, but will not work for a 54. We are currently designing one for the 54. I will post in this thread when the company in France is ready to take your order for SM and will post here when the 54 design is complete. Thanks for your patience. --

Re: Placement of Beta 60 in an Amel Maramu

Larry Salibra
Hi Jean-Pierre,
Keep in mind I've only used the boat 5-6 times since purchase thanks to Hong Kong's stringent operator licensing regime. When I did the sea trial with a clean hull, I saw similar result to Michael on SM251: wide open throttle gave me about 7.7 knots in flat water @ 2600 rpm. It was running bit hot though. As the propeller started getting growth, she started moving a LOT slower under engine. I hauled out a week or two ago and had a small coral reef growing on the prop and c-drive. I've just reduced the maxprop propeller pitch from 18 degrees to 16 degrees based on the advice of the engineer that installed the Beta, which will of course reduce my top speed but also reduce load on the engine. Will see how that goes. More power would always be nice, but it comes at a cost in terms of fuel consumption, weight, engine complexity (turbo!), and money. If I was doing the re-engine myself, I'd seriously look at the Beta 85T that Bill Rouse recommends. That said, I might still end up with the Beta 60 because I find myself leaning towards smaller engines in sailboats. The goal is to sail, not make lots of noise and burn up lots of fuel to push 16,000 kg 1 knot faster. Larry SM140 Sula Hong Kong
