Hi all,

Wonder if you might jhave the knowledge I need regarding a 12 ft aluminum alumacraft I'm looking to buy. I need some information re: max horsepower as would appear on the capacity plates.

It's probably from the late 60's to the late 70's. No capacity plates are anywhere in the boat, and I can't find the serial number or hull id numbers as the inside has been painted with a textured anti slip plate. Even the transom knee is painted.

Reason I need this information is that the seller is selling it with a Mercury 20hp outboard, and I fear that this exceeds the max horsepower rating it was intended for. I've been in 12 ft aluminum boats with 10 and 15 horse, but am not sure of 20 and have never seen. Seller claims that the tag did say 20 hp when his father owned it before him, but there doesn't seem a way to identify it. Alumacraft can't identify the boat without the serial numbers, and they may be beneath that rubberized anti slip coating.

Has Alumacraft made a 12 ft boat during this period that was rated for up to 20 hp? It's essentially the same boat that River - Runner has pics on these forums of, with the same oval decal on the sides.

Any help would be greatly appreciated.

bigdog... Welcome to iboats and here!

As a buyer it's justified to get the id numbers on the boat. It's stamped on the top of the transom knee brace, a little scraping is necessary. Then you'll be able to know about the boat and its hp. rating.

Your thoughts are correct about it being overpowered. I never saw a 12 footer rated for 20 hp max, even when horse power ratings peeked.

I wouldn't run the boat overpowered. For all around use and performance these boats run best with the proper size motor. I don't want to deter you from buying. You could use this to bargain.

If you would, keep us posted.

I just bought a 12' Alumacraft the plate is on it and says 5 hp max. This boat is from around the 1950's so I've been told. It's only about 36" wide.
