Really depends where you are. Hopefully it's not selling on this board or my name is gonna be mud...
Last year I passed on an excellent 18 down here in San Diego which sold on ebay for about 2500. I limited my bid to 2200 because I had a 20 and a 23 in the driveway. The motor was an older, but healthy, Evinrude 140 and the trailer was perfect.
That same boat just went up for sale again in Huntington Beach for 3200. I talked to the guy and told him to post it here but I'm sure it was gone quickly.
The SeaCraft brand is unknown here except to those buying the 95K version in Orange County. " That's like a Mako right???" I don't remember a SeaCraft dealer in SD.
Bottom line the motor - a 22 year old 90 - is worth a 1000 at best , the trailer probably less and the hull - well it depends on the market... say "you don't want to offend but," and offer 2500 and take his temperature. Boat business is stupid - someone makes out like a bandit... How the hell is a 200 etec worth more than a Toyota Corolla that will get you 35 mpg every day for the next 20 years??? This certainly doesn't hold true in the used market.
What is the boat worth to you? That's the top price you should pay.
Look there's a sucker born every minute. Just don't let 'em see you comin'
