My 13 Dauntless is having problems with its transom scuppers. They are below the waterline, and will allow backflow into the boat.

The boat has a 50hp 4 stroke Yamaha. Is that too heavy for the boat and forcing the scuppers under water? Are these supposed to be bleow the waterline? Has anyone had to fix these?

I know some people change out the flap style scuppers and put in ping pong ball scuppers and are pretty successful in keeping the water out.

On my 13' Dauntless I just went to West Marine and got 1 1/4" plugs, one for each scupper. They are a perfect fit. I got the T Handle kind but thinking about it I should have gotten the flip handle style so that they can be removed easier. It doesnt matter that much tho.

I have a 50 2 stroke and Pate tank so I am very heavy in the stern.

Thanks for the pointer. I will take a look and see what can be done with them.

I think that the 13 must have come in about 100 different configurations. In comparison to yours, mine has a bench seat with no back, winshield and grab rail for the CC, and torage boxes that are deck mounted over the area where your pate tank is (this means that to grab the plgs, I would have to reach under the seat to the transom).

One more question...

Do you have the floor mounted through hull with plug (just under the bench and to starboard)? I am not sure what the thinking is for putting a drain plug in the floor below the waterline. I must be missing something.

Thanks again,

It looks like you have trim tabs on your 13. Is that true? Can you talk about performance with and without them?

For the rest of this discussion, I have a heavy motor on my D15. I changed out the flapper style scuppers for the Rabuds (ping pong style) and have little or no water coming in - even when i back my boat off my jet dock into the water.

Yes, those are the small Lenco trim tabs. My Dauntless 13 doesnt plane well at all. I put on a doel fin and it helped a bit, but I have 2 batteries and a 24 gallon tank, 2 large guys, it just needs more help. The tabs are also great because the waters that I fish are almost always 2 - 3 feet and i can tuck the bow down and plow thru it. Never had it WOT with them trimmed up, never got the chance.

I have had the same planing problems with mine. I put on a Dole Fin also, and got some help. The real benefit came from putting on a 13" 4 bladde Mercury Trophy Sport Prop. I probably should have bought the 12" though.
