Here is what I do on all of my boats where varnished teak is used.First of all, from my experience, on all 1979 and earlier Whalers that I have owned, BW used slotted screws, mostly oval head. I much prefer the look of Phillips, so on those older boats, I have removed the slotted and replaced with Phillips. Accordingly, I have a huge collection of slotted Whaler screws! And the cost was considerable. it is simply one of my perfectionist obsessions.
Boston Whaler's old raw teak fastener details don't
t work very well with a varnished surface as far as I can tell. The screws and trims rings cut the varnished surface resulting in finish failure and black stained wood.
There are basically two details they used:
1. Oval head screws with trim rings.
2. Oval head screws countersunk flush into the teak.
On number one, my solution is to install a fender washer under the trim ring, preventing the trim ring from slicing into the varnsihed wood. Anybody with wood on a Whaler knows what I am talking about. Whaler wood is full of ring imprints.
On number two, I 3/8" drill out the countersink, and sometimes it is necessary to go all the way through the wood (such as on console frames), and install a teak plug, sanded flush. Then I re-drill a straight hole. This has to be done before varnishing. Then the oval head screw/machine screw has to be replaced with a same size pan head fastener and flat washer. You can see some of these details browsing around and enlarging some of the photos in this 1979 Montauk album, or even the other boats.
