Unless it's parked in or near the water, usually the worst thing it will do is kill your battery. 60 days is generally not long enough to cause any internal damage. Please do check for the presence of oil and coolant before you attempt to start it.

No problem I don't start my boat motor for 4 or 5 months at a time (V8 GM ). Battery is on a battery tender and fuel tank is full of fuel and mixed with stabil. Just charge your battery after two month (better to keep it on a tender for longevity) and you should be good to go.

no..... but when you restart it... give it a fes minutes to warm up and get the inside of the engine lubricated.....

it won,t hurt nothing to leave it sit that long !
