Drains through transom?

[JONESWR]

The drains on my 1970 Mako 19, do not drain properly. Any following waves bring water in and acceleration takes water out. There are no scuppers on these drains. I am planning a significant overhaul of the gas tank, foam and stringers (if necessary) this winter. Any suggestions on the drainage issue would be greatly appreciated.

Also there are 3 drainage holes through the transom. One is in the center but blocked completely by the newer outboard. Was that an original feature on this model?

I think that was an inherent problem on that model. When I trailer my 201 I plug the drains from the inside to prevent water backing up in the engine well when loading and unloading. You could do that.

Or install ball scuppers.

I think the center drain was common on early Mako's. I had one on a 25 I had.

I prefer the through transom over shower drains that came about later. My 224 had similar set-up, and when I did my transom I went back with just the 2 corners; made the holes larger. I have these flaps with wedges and do not have an issue with water coming back in.

Thanks Naname Dave. Great short term solution. I appreciate it.

Thanks ChuckB. This looks like a good improvement for the transom. Thank you for the suggestion.

The only way to fix that problem completely is to raise the floor. I have the same problem in my 17 and I keep the plugs in all the time. Before I repowered I could leave 1 out and put weight on the bow to help the hull drain, but now with the new 4 stroke its too heavy to self bail.

I can see how that would work. Thanks for the idea.

ping pong scuppers would help as well. but as others have said it's just a bad design and the floor should be higher.
