Re: uni flite cuddy 17.5 ft
Seeing as no one else has chimed in.... I'll take a crack at it. IMO, boats that age (you didnt say, im assuming late 70s early 80s) it's all about condition. Really check it over for rot in the floors etc. It should look like she's lived inside her whole life. If it doesnt, it'll be rotten, again my opinion.
Also, IMO, the outboard is most of the value, so youre really paying 1k for a 115 merc. It better run great, start easily etc. A compression test would be a good idea.
