I found 2 YouTube videos on Lithium Ion batteries that I really like. The batteries were disassembled by Will Prowse:

I always felt the anchor wash on the SM did not do a great job. After a minor collision at the bow, it became even less useful. Finally, the pump developed a major leak, not fixable. I have put in a

Doe anyone have a photo or two from installing an external regulator on their Leece-Neville 175amp alternator? I have the wiring diagrams from a previous post but was wondering if someone had an

Hi James, Since you plan to pull the shaft and check it at a machine shop you should also check that the prop is true. Many years ago (1991) I had a similar problem, it was on my first boat a 35’

James, I thought of one more thing that possibly could be causing the noise. I installed a cutlass bearing once that was a bit on the tight side, apparently a manufacturing issue. The Cutlass

Hi Dennis, Yep tried that. I need to do a rebuild on the alternator anyway. Did you have any issues sourcing the bearings? -- James Maramu #147 (1984)

Thanks James, I used your easier method last time. Might try the "fancy" method now as it did not solve the issue. Then if it continues at least I know it is not that. -- James Maramu #147 (1984)

-- Thanks Nick. Your description is perfect. I will have another go at the alignment. Due to location and with no assistance around at the time I did it myself with only advice from other

Dennis, that created a dead short of the house bank. Something melted because there is enough amperage in the house bank to weld. Look for a burned wire. Also, try to find the shunt for the battery

Pat, Steve would know better than any of us. -- CW Bill

You need to get a meter and check the voltage at the main on off switch inside the engine compartment. If there is no voltage there there may be a fuse on the battery terminals that have blown. It is

Steve, I have only over the years lost no more than a 1/4 of a cup if that. Based on what you describe there seems to be adequate lubrication to spare, and as much as I am not looking for any

For everyone having rack problems, they are cast aluminium on our SM. Little wear showing on mine. Cheers Jean-Pierre Germain. SY Eleuthera, SM 007

Electrical issues are not my strong suit. I had my house battery alternator off for a rebuild. I took my Maramu out for a day sail and upon return to the harbor, my house power failed -everything,

Hi Duane, sorry for the late reply, I have been at sea voyaging. Try washing the salt out with a fresh water hose and then when its dry, spray it with silicone. A salt build up will stop or create

Hi James, I believe you have a shaft alternator right? Try disconnecting the belt and see if the squeak stops. We had a squeak and it was the alternator bearings. Dennis Libertad Maramu #121

Hi Pat, I would suggest you do not attempt to add a grease fitting to the Racks. The steel racks take up almost all the room inside the black housing they are fitted into, and I’m not sure you can

Pat, I do not think it is possible to "replace the worn metal through welding in new material and then fashioning new teeth by filing." Let me know how you fair on adding a grease port. --

Bill , I may go ahead and try to add a nipple,if as you said the wall is too thin to tap , I will seal it by other means. I will in the future tie the wheel off center to spread the wear as per

James, I replaced the original Amel engine mounts on my Maramu #220 this year. The part you have circled is the bronze stern tube which will extend into the hull. It appeared that mine was bonded
