In every instance I had the seller deliver to the mechanic of my choice ( I had to search one out several times ) and at my cost had it done. ie :local marina where it was serviced. So if you like everything on it etc and settle on a price simply make it subject to compression test at your expense-seller to deliver to mechanic for testing. It was the cheapest money I ever spent and said goodbye to ---turned out it had a cracked block!
Probably has the GT-40 pcm engine (visible on the engine cover) which is an awesome engine. Lots of power.
Re the vinyl----did they match the exisiting or not ( I am fussy) . If not to me that is a detriment as I would want it done right to match. So if some was done then pay great attention to the rest for cracking , seams splitting etc. Lift the seats and turn them over etc.
Doubt the boat does 50 +---nice hull and engine --maybe 46 /47 tops!
Cover is not a biggee --can get a new mooring cover for $300.00 if need be, custom to the model.
tandem axle trailer new is about 1500 to 1800 more than single axle.The ad I sent you was a tandem axle.
The ad was from a local dealer who took it in on trade so you know he didnt give that much on trade as he needs his margin for resale.
look it over very carefully--has it be beached?? ( wear/scrape marks under hull) how is prop and struts?
I really like this model personally but just make sure you get a good one!
