Hi there! I have been poking around on the forums for some time now (search feature works great) and have found a great deal of info, but I have come up short on a couple of topics.
I have a new to me, used 1985 two stoke 25hp Johnson, model # J25RCOS that is manual start and short shaft. I am hoping that someone can tell me what would be needed to make this motor capable of charging a small battery to run some basic electronics like a fish finder, or maybe charge a hand held GPS or VHF.
This engine came with a early 80?s 15? Zodiac MKIII GR and both will likely need some work as they have been stored for over 10 years. So, I don?t as yet even know if the motor runs, although I have pulled it thru a number of times and inspected the visible portions of the pistons and cylinders thru the spark plug hole and did not see anything that would indicate a scored wall or melted piston. I plan to hook her up and test run it this weekend in a garbage can full of water (if she will start), but regardless of the results will be taking it to the local outboard guru to have the impeller replaced, compression check done, fuel pump diaphragm replaced, and everything checked out.
I am quite concerned that this particular engine does not seem to have a tethered kill switch installed? instead it has a push button kill switch on the front panel adjacent to the primer. Is there an aftermarket type kill switch that I can add? And does it have anything from the factory that would prevent it from being started in gear? I don?t think it does?
I live in Anchorage AK and the primary planned use for this set up (early 80?s 15? Zodiac MKIII GR) will be for short fair weather family (5 total, me, the wife, 6, 4, & 2 year olds) fishing trips in fresh water lakes, Cook Inlet and PWS out of Whittier, Seward, Deep Creek and Homer. Never out of sight of land? and as I said, only with good weather! Additionally this set up will be used for a once a year fly-out lake hunt. It may also see use on the big and little Susitna rivers, but not until I get the hang of using it and driving it around on open water. That said, I have been told by several persons that the ?Rock Hopper? prop and skeg protectors are the way to go for what I want to do, so if anyone can refute that, or confirm it, that would be great!
Also, any other bits of advice or cautions regarding this motor that you would care to offer would be graciously accepted and appreciated!
Thanks in advance for your help.
