Sea Nymph 161 rebuild

[S Gilbert]

So now I have 2 metal boats to build.. my 1987 Lowe 14 that I will be replacing the transom and floor on and now a 1992 SeaNymph 161 with a 92' Evinrude 50 and 9.9 hp motors. The Nymph is overall in good condition and will be replacing the marine plywood, little that there is and the carpet. Main issue is that it looks like I will need to rewire it all. Questions are:

1) Does anyone know if there is a wiring diagram anywhere? The last owner was going to replace the fuse panel and tossed it out, so I have plugs but no idea where they go.

2) I am considering changing to a permanent tank and looking for ideas and suggestions.

If anyone has some parts that may work on this moat let me know.

Thanks

I have a 1992 Sylvan 16' with a built-in fuel tank. Under the floor about 2/3 of the way toward the rear. 18 gallon plastic Moeller tank, works great but fill cap is in a bad location, often thought about changing the location. Any pics on your sea nymph ?? Most boat mfgrs do not create a wiring diagram....never saw one in my 60 plus years....engine yes but not boat itself.
Any wood in the transom ? My Sylvan is all aluminum, only the floors and front deck are wood. In the near future, the carpet will be coming out when time to replace the floor wood....

Sorry I have been MIA.. old computer died and I've been tied up a ton lately. Hope to get the 161 into the garage to start pulling off the carpet glue. The interior is about all apart so it can be rewired etc.. Part of me wants to put in a built-in tank but haven't yet figured out how much work it will be to pull the side compartments, main floor and then install the tank.. trying to see if I can find a video of what would be the project..

Pay close attention to the transom on that boat. OMC era Sea Nymph, Princecraft, Lowe, and Grumman, all had big issues with using corrosive marine plywood for the wood core in their transoms. Everyone of them I've ever looked at or dealt with had some degree of rot on the transom panels and even the transom rivets from the cupric sulphate used in marine plywood. They somehow got the bright idea to use pressure treated or marine plywood for the transom panels somewhere in the mid to late 80's and it continued well into the late 90's or nearly until their demise.
I've seen more than a few Sea Nymph and Grumman aluminum bass boats with the telltale signs of rot around the upper corners of the transom and all along the edges of the wood panel where it was most likely to be exposed to moisture which sped up the rot.
I can't say if they corrected this before the end in 2001 or not but I walked away from a 1997 Grumman the other week with some pretty bad transom rot and have not seen a rot free Sea Nymph in decades here.
