Scupper Drains : How far above the waterline ?

[RebelYell]

..

Howdy Aquasport Boaters -

I have been reading ( and occasionally posting ) in this forum for months.

In March, I purchased a 1990 Osprey 200 with a Mariner 150 of the same year.

I have been going through the boat and notice that occasionally, when I stand near the transom, a little water comes in through the scuppers. Never much, but maybe a quart or so. I weigh 220 lbs.....

My question is:

How far should the scuppers be above the waterline for my boat with my motor and say, a half tank ( 22 gallons ) of fuel...without me in it.

I am trying to get a general idea. Also, a guy at the marina who forklifted my boat a few times said it felt somewhat heavy...of course this is an older boat with a solid (non cored) hull so it should be heavier than alot of the boats he handles. I have never inspected the stringers and am praying they are not wet.

Thanks for the input and hopefully I can get a general idea of what a reasonanble height above waterline for my scuppers should be.

I really enjoy this forum !

That is going to be the norm for the Osprey's.  With no one in the boat, they should sit just above the water.  When a person stands at the back, the scuppers usually become submerged.  Do a search on the forum for scuppers and there are several threads on this.

Thanks man.

Reading all this stuff about wet stringers makes me nervous; as I am getting ready to paint my baby with Interlux in a couple of months.

Could one assume, then, if the scuppers are just above the waterline that the stringers are prolly OK ?....as in no more excess weight ?

Also, on the stringer topic, was this a problem in the later manufacture boats or is it a problem for all models young and old ?


You guys on here rock.  8)

My 230 is fine but the scuppers are under water on my 170 all the time.   Too heavy of a motor I guess.

My 22-2 burps a little water now and then if there are a couple of people in the back.

Heck, check out a $40K Pathfinder.  Lots of manuf. have not learned yet.

sounds real normal for the scuppers to dip below the waterline when an adult male is far aft on that boat. If that amount of water bothers u, or if u have 3-4 passengers often, u can upgrade ur scupper design to the rubber flap design, or even more effective "ping pong"ball design. Both intended to get water out but not allow any in.
      BUT, i think u said u were going to the trouble of painting here,and if u ever repower, modern 4 stroke and d.i. motors weigh significantly more. In my friends case bringing his scuppers under water at rest at the dock. . After investing a bomb in a new 4 stroke, he had to glass up the old scuppers and create new ones somewhere around and inch higher. Just a thought but worth mentioning
