Different Typhoon Scupper Drain installation

[Markst95]

I've done the unthinkable and installed cockpit drains on my Ty without seacocks. I used larger (1 1/4) Marelon thru hulls, installed them with 5200 and marine sanitation hose. My thinking is if I'm on the boat and there's a failure I'll just dive overboard and shove a wood plug in the hole. I went with larger thru hulls to help with the draining problem. So far they seem to drain very well.

I can understand why you did this but if one scupper starts to leak with valves you can at least shut it off. The only other thing I would do is to position the screws of the screw clamps on opposite sides of the fitting - this avoids and small leaks that could occur between the clamps. The weakest point is the hose so if the valve is plumbed to the hull, you can always shut it off.

Mark, you don't have to dive overboard. You can still plug it from the inside with a plug that fits the hose or the thru-hull.

Keep some plugs handy, on the inside near the holes in your boat. A sharp knife, too.

I assume that hoses leak at the exact same time the wind is up, the sky is black (except for the lightning part) and going in the water is a BAD idea.

Thanks for the idea on the clamps, when I installed them I was thinking about angling the tails so I wouldn't get caught on one, there somewhat sharp. I'll move one if I do have any leaks. I did start out with the intentions of putting in true seacocks, I even bought some but there isn't enough room to install them unless you cutout a big chunk of the quarterberth supports. I had to slice a groove out to even use the bigger thru hulls. Anyone else have any pics of their thru hull Ty setup???

[RIKanaka]

Mark, these pictures are not from my boat but from someone else's on this board. They are the 3/4" true seacocks from Spartan that were used on later model year Typhoons. Mine came with gate valves that I changed to ball valves.

Its interesting to see the changes over the years on the Ty, It looks from the pics they moved the thru hulls to be more in line with the drains. The bilge access is more aft than mine as well. It would be nice if we could put together a timeline of the different changes occuring through different years. My boat is a 72 and it seems like they did some changes for the 73's with a molded shelf in the v berth. Although most changes seem to be improvements, some haven't worked as well, like the teak at the base of the tiller which can leak as apposed to the raised fiberglass area.

Mark, I like it! If you had some tapered plugs and a spare hose you would be bomb proof. Those 3/4" scupper drains may be big enough to drain the cockpit but are very easily clogged.

You have increased drainage and eliminated components that could fail in a critical application. Not bad. I always wondered how practical seacocks were on cockpit drains that always remain open.

The hose runs on the standard TY set up are horrendous. There just isn't enough room to make nice fair bends. That coupled with the small diameter hose makes for a marginal system as far as I can see.

Good job, Steve.
