I have been replacing old hardware and adding new to my boom this year and found that I had accumulated a lot of unsightly screw holes. Looking through some of the mounds of reference material I have stashed away, I came up with this simple fix - cut off a stainless screw the same size as the hole and screw it in. I cut all but two threads on each screw with a Dremmel Tool cutting wheel. The result is far more appealing than having all those screw holes everywhere.
You may not have to cut the screws off, however, with an in-boom outhaul system, I thought it best to keep internal obstructions and potential hang-ups to a minimum.
By the way, if your looking for a great all-purpose tool for boat maintenance and repair, it's the Dremmel Tool. It cuts stainless steel, shapes, polishes, grinds, etc., and when used with wood-cutting bits, is great for cutting holes in bulkheads without scratching the surrounding area and in tight spaces.
Al, I'd think that aluminum pop rivets would also be a reasonable way to fill non-used holes.
I agree with the dremmel or a suitable rotary tool. Just this week, the heater hose fitting coming off the thermostat manifold (a rather involved manifold Ying to both heads) on my work truck broke off when I needed to bypass the heater core until it can be repaired. Figuring I was in deep doo doo, there was nothing to lose by trying to clear the hole, which unfortunately wasn't easy to access. Noting the softness of the broken fitting, I used a rotary tool with a burring cutter and was surprized at the ability to clear the hole of the pewter down to the pipe threads after cycles of grinding and inspecting with a mechanics mirror.
Getting the pewter out of the threads required a little more effort and I wished for a small wire brush for the rotary tool which I thought might have cleared the threads. After some initial and failing efforts to pik it out, a rough effort produced a tap by using a cutoff grinder and cutting slots in the end of a pipe nipple. This proved to work well cutting the pewter from the threads.
When a brass plug was safely in the manifold... a great sigh of relief could be heard for a block.
I had thought of using ss or aluminum pop rivets but wasn't sure how much of the rivet extended inside the boom. I'm a little sensative to my internal outhaul catching on long screws, rivets, etc..
