    good for Grumman canoe transom

    I needed to replace the rotted motor mount boards on my 1973 Grumman square stern canoe. I paid >$65 for Marathon's "OEM replacements", which were smaller, full of voids, and generally low quality; far inferior to the originals. These samples are large enough for 2 of them (I used 1 ea 12mm inside & 1 ea 18mm outside) to be cut for replacements, and can be easily painted (or varnished). if needed The outside board is about 1/4" shorter than the original, but still larger than what Marathon sent me. Much better quality than the alleged OEM replacements at less than 20% of the price :-)
