Hello everyone.. been a while since posted. Does anyone know type of bolt used for the hole in transom ? I would personally just plug it fiberglass or something but guess its there for a reason as a drainage hole .

It looks a little high. And it looks like you're missing the threaded receiving end for your plug. The make thu-hull drain plug fittings. If you go bronze, it should be grounded to your system.

Looks to high for a hull drain and to low for most other uses there is no thru hull fitting .
Hope fulling sopme one with the same boat will chime in and say what its used for or if its something someone added

Could be for access to the strut bolt/nut?

More bilge .. I cant see using the hole while boat in water though lol

Looks to be where the center support for the swim platform would be,not sure why so large but maybe a start to a repair---- Mike

I didn't think the F25s had prop tunnels... I thought they were standard V's. Has someone reworked the bottom on this one?

i dont think it belongs there, id get a wooden dowl and some 5200 and plug it if you cants foresee a use, over the years i can recall at least 3 boats I had with unknown holes in the hull. The first was a 20ft Citation with about 6 evenly drilled 1/4in holes on the bottom near stern, possibly for a added chine? Those got pluggee with golf t's and 5200, The second a 26 Silverton with one less than 1/4 hole directly and randomly in the bottom of the boat near the rudder possibly as a weep/drain hole some dummby with a drill drilled? The boat had sat for awhile, that got plugged with a chop or toothpick and 5200 coated with marine tex after, the third was a 21ft Sea Ray the swim platform had broken off, the original bolts served as plugs in this case also with 5200.

I am thinking same thing k4282.. talked to owner I bought it off.. He said it is a bilge drain plug but he never had boat in water and didn't come with plug it self. I may just plug it and seen on kijjiji they sell plugs with led under water lights .. may look into that

your hole may be a little large but i see where your going, i have 5 of them on my boat, below is a picture from last year when I had 3

I recently drilled a hole in the bottom of my F44 to drain the keel. I bought a large Perko plug that had a flush face to it with a square key hole and installed it with screws and 5200. I did not want the typical drain plug for my hole is on the side of the keel and if I hit something, I did not want the bolt sticking out.
