got a few questions on rebuilding my 170 CC
« on: October 12, 2016, 09:15:06 PM »
i have a 1974 AS 170 CC and it has a hole in the hull and water has water logged the foam in the stringers, would the 2 part foam work to replace it?  also where can i find another hatch for the front casting platform? when i got the boat the front middle hatch was missing.
thanks

Bummer, I had a parts boat and the center hatch was replaced by a piece of stainless steel, otherwise I would give it to you. I'm opening up the floor on mine soon and if the foam is wet I'll be replacing it with 2 part.  I was looking at the product from Aeromarine based on price. One note I learned in these forums is the foam in the stringers is structural, so use a 4# foam inside them, and 2# foam in the outside cavities. 

Here is the link to Aeromarine.  I'll let you know if I go with something else.

I'm doing a rebuild on a 72 170 and at the point of replacing foam in stringers. How much pour foam would I need per stringer? I have never worked with this product before.

A 1 Galon kit (1 gal A + 1 gal B) of 4 lb foam makes 4 cubic feet of foam. 

Maybe someone knows the volume for 170 stringer, but if not:

Measure your stringers (Width at top + Width at bottom) divided by 2 = average width.  Estimate average height.  Average width x average height x length = volume.  If you measured in feet, that's how much foam you need per stringer.  If you measured in inches,  Divide by 1728 to get volume in cubic feet per stringer.
