To determine the motor's HP, I would look for a serial number plate on the motor (often on the mounting plate) that may also have the motor's model number on it. My motor also has a "140" at the beginning of the serial number which indicates the horesepower but I don't know if older models had the HP in the serial number or not.
How is the windshield held up on the driver's side? It looks like the pole coming down from the windshield is aimed at the steering wheel or is just not attached?
Also, I noticed that the motor has what looks like a "Hydrotroll" plate on it, like this one:
I had one of these plates on a prior boat and I had a heckofa time with keeping the thing in the up position since it would never lock in place and would break the shear pin off. I went through countless shear pins and it never did work right even though I tried to tweak it (adjusting the spring and shear pin mechanism) many times. Seeing that it is in the down position makes me wonder if there is a broken shear pin or none at all. btw, I've read of others having problems with that plate as well -- see this link
. So, just a minor thing but that is something you would have to deal with.
Overall, it looks like you have some work ahead to get the boat into good shape but if you are willing and able to do this at least you have the whole winter to work on it
$1000 does not seem to be a bad price, but make sure there are no leaks! There are still times I wish I had my old boat which was smaller and easier to deal with, so the size of the boat you are looking at is a real plus IMHO...
