Re: What would be a good price?
since they will both need work I would go with what was said before.... $1000 each for the ski's and take a look at what type of trailer they have but I would not go more than $400 for it max.
at $750 - $1000 or less each you have some room to put some money into the skis and still be at a fair price. if they have sat for that long they will also need 2 new batteries which will be close to $80 right there, $20 to change pump oil, $8 spark plugs, $40 for good fresh oil and if you have to have the carbs cleaned that could be several hundred $$ each. I would do a compression check on each one first... the last thing you want to have to do is put a motor in them... also jack up the trailer and spin the tires to see if the bearings are any good and check wiring... at that age it may need new bearings.
People seem to thing if something has sat for years and years that it is a good thing when infact it can make things worse. you need to find out what was done to them before they were parked.
when you run them for the first time check all fuel and oil lines and pre mix the 1st tank at 50:1 with the oil injection full to be sure it is working.
for the most part when I purchase something like this I take the cost of everything that would need to be done to make the boat 100% and subtract that from the low end of what the boat is worth. and NEVER pay more than you could turn around and sell it for easily the next day. Remember the biggest POS can be cleaned up and made to look amazing.
If you feel the price you give him may be a bit insulting just write something up stating the cost of everything you will have to do to them with a total and justify your price… the last thing you want is to buy them and have to put far more into them than what they are worth just getting them running before you even hit the water.
