I've been restoring a boat the last few years, now I'm kind of hung up and need some help.
Here is the background, my grandfather purchaced a Cobalt 18 foot bowrunner I/O new in 1976, I grew up riding the boat (he kept it in great shape) one year in the mid 80s it didn't get winterzed right and it froze the block. A couple years ago I took it off his hands with the hope of getting it back up and running. It was kept just like I remembered it, the vinyl and teak wood were all in almost perfect shape, I rebuilt the OMC (Ford 305) and it runs great.
Here is my problem, the places here in town suck at doing work on boats, I dont trust them as I have had some problems before. I want to change the fluids in the stern drive itself. I have a OMC manual and it goes over how to pull it all apart and replace major parts, but I can not find one place on how to just change the fluids.
I would like to change the upper fluid, it has a screw in dipstick right on top of the drive (flat spot) but cant see where it drains, also dont know what to use (I have heard they are picky).
I would also like to change the lower fluid as well, there is a screw in the middle you pull to look for water and level, and a lower one that looks to drain it, do I just drain it out the bottom and then squeeze new in till it comes out the top, if so what (once again heard the electric shifts are picky....there has been some mention of "type C?") and how much.
Lastly there is a little gear that raises and lowers the sterndrive, it has a screw that checks a level and nothing comes out, it says something like "only use OMC xxxx oil" but it's been painted where I cant read it and I have no idea what to put in there either.
It's a 1976 OMC electic shift stringer (I think, does that sound right). I can get some pictures if need be, just dont want to screw it up, but at the same time want to keep it properly serviced.
Thanks again for your help...also my first post here.....
