    Following your thread with interest. These are the kind of details that will benefit any model. One thing to note, however. Its generally not recommended to use solder connections on a boat. Solder connections are brittle and generally don't hold up well to the vibrations.

    Today was maintenance day.

    First time changing oil on a boat for me. I usually would get the marina to service my previous 260 DA but since I went into this older boat purchase as a DIY Fixer it was time to get a bit dirty.

    The 5.0's got some new life blood and filters as well as the generator and topped off my drive oil monitors.

    First off "Well that was fun" no one ever said when they had to change the oil and filter on the generator of a 290 DA.

    I used the TopSider oil extractor which worked out very well including the generator.

    The engine oil filters were a bit of a bear to remove..... seemed like Hercules must have tightened them at the last change or they just got tighter as time when on. The filter on the generator was a PITA to get to and change. Had to do it all by feel since you can't see it.

    I used a oil filter pliers on the larger engine filters and had to use a filter socket for the generator.

    TopSide extractor removed a good 5 qts of oil from each engine which supposedly only holds 5.5 qts. I removed the oil from the generator through the drain tube and then after removing the dipstick I sucked any remaining from the hole which was not much as all.

    I know it will be a bit easier next time but boat mechanics really do earn every dollar.


    No one in their right mind engineered the generator for maintenance.


    Had to use this on the generator to remove the filter.

    Generator is a nightmare. I took the heat exchanger off this year to get the old zinc out and flush the coolant. Lots of cuts on my hands after that one.

    Had another fun weekend. Kind of.

    2 weeks ago while I was changing oil I noticed one of my batteries were leaking. So this weekend I went ahead and changed out all 3. The batteries that were on the boat were Group 29 (13" long) and for some reason Group 29 must have been superseded so I went with Group 31 which is also 13" long. The old batteries were 4 1/2 years old so they were probably on borrowed time.

    I was originally going to replace with flooded lead acid but could not find what I wanted locally and batteries plus convinced me to replace all 3 with Deep Cycle AGM's.

    Installation was a PITA. Whoever decided to squish all 3 batteries together where you have to drop them in through a little access hole should have to walk the plank. I think I left behind a bit of DNA on every sharp object possible. Especially that dam hose clamp on top of the generator.

    Once installed I reprogramed the ProMariner to AGM and all went well....... I never saw so many green LED lights before. ;)

    One thing I do need to correct is my time estimates to do boat maintenance ...... what should have been an hour job was like 4. I guess I'm going to just x4 what ever pops into my head when I think about doing something.

    After cleaning up the battery area and wiping down the trays and everything else I could reach.......Don't they look pretty.


    I modified some terminal covers for 4 connections and used tie wraps to secure but what kind of terminal covers can I get for the daisy chained battery?

    EDIT: I ordered some "flag terminal" covers for the battery connections that are unprotected in the picture above. These are designed just like the terminals themselves. I'll still have to cut them and use tie wraps to secure but this will be one more thing corrected from the pre-purchase survey.
