Just about to go and dig my boat and engine out of the store, I haven't run the engine since October (when it was new and ran for 4 hours), I didn't do anything to the engine after last trip, bar flushing it with fresh water.
The engine is a Yamaha 20 hp, 2 stroke
My question is; do I need to have it serviced or seen to by a dealer at all before running it?
If it's that new will you not need a dealer service to protect the warranty?
If not, I assume it's an autolube machine? If so I'd run the first tank of fuel (or just half a tank if it's empty) with a 50:1 mix - it'll smoke like mad, but if you got any air locks in the oil system when it was in store then the engine will not be damaged. A few mins on "neat" petrol will clear it afterwards.
Gearbox oil probably worth checking / changing after 4 hrs use if it's new, even if it hadn't been in store.
Apart from that the usual does the deadman work / is there coolant coming out? checks will probably be enough. I'd normally say check the electrial connectors for corrosion / looseness, but if it's less than a year old I'd be surprised if any problems there.
There might be more in the handbook. I think there's also something on the Yam website FAQ pages from memory.
if i remember correctly you are supposed to run the very first tank on 50:1 anyway - with the yam 20HP. With 4 Hours on it is probably still on the first tank full. Your gear box oil will be due for a change at 10 hours too if I remember rightly. If its got remotes it would be worth checking they are still attached properly (mine got knocked loose once) and greasing them too. The only thing i have found sticky after storage has been steering. Fresh greese and a good wiggle from side to side seemed to sort it.
