When you pulled the wires under the pan where did they come up to attach to the engine?



From the back end of the engine, what you see if you remove the opening in the aft cabin.  Just forward of the stuffing box, below the transmission/shaft coupling.

Jon- I am still in the yard, unfortunately dealing with some frustrating yard BS/scheduling delays and semi-incompetence, (giving them the benefit of the doubt on that one),  but I pshould be back at my slip this weekend. You are welcome to come by and look at the routing I took for my wiring.

Hi Stu, no hole in that area on my boat. There is a pass through to starboard that the water hose from the aft tank routes through to get to the galley sink area. Your area would be a simple path to fish wires through. Might be worth drilling a pilot hole to put my borescope through and take a look.

That would be great Noah thanks.

Jon,

Here's the back of the engine with the space underneath.

The red wire on the right is my new alternator + to the house bank.

The hoses on the left are the new hot & cold lines to the head sink that I pulled last year.

Ken,

If you tie back up to a dock at the end of a day, no big deal, if you don't your batteries will suffer....

For those who have not read it this article delves into why voltages sensing is important if you want optimal charging performance and optimal battery health.

Voltage Sensing - Why It is Important


Thanks RC that's a great explanation and article - really explains it with no fog involved. 

Do you carry the conversion for an external regulator on the 51 amp 8MR Moto alternators?
Could a shop convert the 8MR from a self- to external-sense?

Thanks

Hi Stu, Completely different construction from what I have. Gives me hope that I may be able to use that space after drilling a few holes. Thanks for the photo.  Jon W.

Ken - I got my 8MRxxxx, conversion kit, and pulley from http://www.ase-supply.com. It was easy to do the conversion from internal to external following RC's instructions on http://www.pbase.com/mainecruising/alternator_conversion

I purchased my 90 amp Leece alternator and external regulator conversion kit from Spyder Marine in FL.

Thanks Craig and Noah -- I have a kit dialed in...
I thought that RC had a kit for sale at one time and would have preferred to give him the cash.

Cheers

Hi Jon,

Not sure why you need to drill holes for your wires.

From the back of engine, under the bed, you have access to the head cabinet, then you can access under the shower pan to bilge.  From there you can go to the settee by the nav station and up to electrical panel.

This how I ran the cable for my solar pannel to panel.

I'd rather not having to drill holes.

Hi Patrice, that area is very crowded with thru hulls and both my bilge hoses pass through to get to the transom. Worth looking at again though. In the second attached photo you an see both bilge hose passing under the aqualift muffler from the head.

Hi Stu, I've attached photo's of the back of the engine, same angle as yours showing that it is closed off. You're lucky you can run both wire and hoses through those openings. I want to add a second bilge pump but finding a path to run the second hose is a challenge. The third attached photo shows the starboard side of the engine where my aft tank water hose runs to the galley. It looks promising for the cable but not as big a space as the hole would make you think. More looking tomorrow.

Jon, it appears obvious to me that someone (a PO) ADDED that "enclosure" 'cuz it simply ain't factory OEM.

Drill away.   :clap :clap :clap
