Using engine for first time this year

Hi all,

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.

Hope this helps.

Thanks 9D280,

It is an Autolube, I actually did the first half tank at 50:1 as you suggest, and yes it did smoke like mad!

Will drop a bit of oil in some fresh fuel and get out there.

Thanks!

Al

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.

Maybe overkill but take out the plugs and chuck some oil down the holes - turn the engine over a few times before putting the plugs back in.

Just noticed you said october - shouldn't be needed - it's only 3 months!!!
