Worth it or not?

I have found a 1987 v20 cuddy cabin for $1500. I can probably get it for $1000. The hull transom and floor appear solid and in good shape, however it was night so I need to go by during the day and take a closer look. The upholstry is horrible, but I want to put in helm seats anyway to open up the deck more. My main concern is the motor, it is the omc seadrive. I believe it was the 2.7 Litre. ??? I am not familiar with these motors. The boat has been sitting for two years and is not currently running. The powerhead on it is newer and appears to be in good condition. The prop was stolen so information on what is the best prop would be to replace it with would be appreciated. How dependable are these motors and how well does the boat ride with them? It has a trailer that needs new lights and some maintanance.
