I posted this in the build part of the forum, being an OMC, it may get a better responses here.

My engine mount stringers were bad so I cleared the area last year and I just cut new ones last weekend.

I cut a section of the floor out to see how long they went and the more I cut, the more bad flooring and stringers I found.

My question is, it looks like there is only 2 factory stringers on the hull.

The original engine stringer was 2 2x6s sandwiched together. 1 2x6 was the length of the bilge box and the other stringers was a longer 2x6 that ran to around under the dash/steering wheel area.

I now have the whole floor taken off and I still don’t see signs of any other stringers.
There looks to be like a random 1x2 or 2x4 on the sides that someone just wedged in there.

The new engine stringers I cut are from a 4x6. I cut the 4x6 to match the 2 original 2x6s.

My question is, do I just add the new engine stringers and glass them over with new plywood?

Do I have to add ribs?
A second set of stringers on the outsides?

I used the boat like this like 6 times and it didn’t break, and I don’t see where more stringers would have been installed at the factory.

I still need to remove the foam.
The 2 center red lines represent the engine stringer and the outer lines represent where I think someone else put a 1x2 but didn’t glass it in.

Thanks.
