We just inherited a 1968 16' Fiberform boat with a Marc 500 50HP of the same vintage. This thing should fly across the water, but it's like a slug, never quite reaching plane. I now understand that the hull is foam filled. So, I drilled a hole in the bottom of the transom to see if there was water in there. Alas, it's been 3 hours and I now have about 3-4 gallons of water in the bin I put under it, and it looks like coffee.
Upon further investigation, I discovered a 8" x 10" FB patch 1/3 of the way back from the bow right along the keel, and it's ugly! Before I moved the winch post back so the stern would sit on the back roller, this is where the boat sat on the trailer roller. Whatever happened, it needs a better patch.
This is leading me to believe that only the center two spaces may be water-logged, and indeed, this volume of water would prevent the boat from getting on plane. From photos of the ribs, that space could easily hold at least 100 gallons in it. At 10lbs per gallon, ....there's my problem.
I'm looking for options of removing the water soaked foam, options where I don't have to replace the floor. I have a series of questions I'm hoping you people can answer.
I'm thinking about removing the patch and using a concentrated blast of water from the garden hose to remove the saturated foam. Thoughts?
Anyone know what kind of foam it is?
Anyone know how important the foam is, as in, should I replace it, or can I leave the space empty? The floor is new; 3/4" Marine Grade plywood heavily coated in a rubberized 'Sure-Grip' deck epoxy, so I don't really need support for it. Also, when I drilled the holes in the stern, drilling into the center keel showed a lot of solid wood still in it.
Any suggestions you can offer would be great!
Thank you in advance.
