For starters you need to empty the old gas and put in new gas. Swap in new plugs. Probably gonna need a new battery Then try to start it. You may get it to start. If that works, take it out for a spin. I would also do a compression test. That is the best case scenario. Other scenario is it needs carbs cleaned and new fuel lines. Worst scenario is engines could be toast if it had water in them. I would offer like 1500 bucks prior to it running. If it runs, I would still work it down to like $2500. Good Luck and come back with any questions.

There is a fella named KustomKarl, That has a bunch of threads about bringing a motor out of storage.
I brought mine out of storage to find Oil in the bottom of the crankcase. Leaking seals.
I pumped the oil out and they ran fine.
Good Luck and Let Us know how all turns out.

How old would you be okay using old gas for? 6months? a year?

What about oil?

That depends. Did the previous owner add marine stabil? If so, i wouldnt worry too much unless its been over a year. Mine sits 8 months from sept till may and i never have a problem in the spring when i fire it up. As far as oil, it really doesnt hurt it to sit long periods. Just make sure to use the correct oil. Use wat the previous owner used unless it was the wrong oil.

... Use wat the previous owner used unless it was the wrong oil.

Can you test the oil to determine what it is? Do garages have a device to measure that?

It took me 3 months to track down the owner to buy this boat (at a steal of a price nonetheless), so I'm doubting I"ll be able to track him down again to ask about oil.

If its blue. Its the wrong oil.

No way to really test. The color sometimes helps tell you. I would either use the boat till its very low or drain it out and add new.
