New Engine Has Been Sitting A Year Ready to Start?

I bought a new Yanmar 3YM30 last December. It has taken me this long to rebed the engine compartment and getting everything set to go. I am now ready to start it up.
a) Should I be concerned about the rings/pistons?
b) I realize the impeller might be malformed and might require replacing but I believe it should work for the initial run. Thoughts?
c) Should I spray anything in the cylinders?
d) Should I manually turn the engine first? If so what direction facing from bow to stern does the main pulley turn when running?

Thanks in advance
Spencer

We were in the same boat (lol) turn it over first. if it spins there shouldn't be a problem. I don't know if I'd be worried about the impellor either, ours doesn't seem to have suffered.

Hi, Shouldn't be any problem. I'd probably change the impeller as, if it breaks up, it'll dump bits of of rubber in your heat exchanger. I would also disconnect the engine stop wire so it can't start and then crank it on the starter until the oil light goes out - then reconnect and away you go !
[ spraying anything in the cylinders would involve pulling the injectors so don't bother ]

Agreed, you should change the impeller. Having to clean out the heat exchanger is extra work you don't need and the impeller blades may crack from being started dry, run fine for a while and then come loose creating creating a problem down the road.

Agree with the 'run without starting till the oil light goes out'. The engine should turn clockwise when looking at the crankshaft pulley.

Re: New Engine Has Been Sitting A Year Ready to Start?

See page 34 ➥ http://www.yanmaritalia.it/amministr...V2_21JAN09.pdf

“... NOTICE: When performing engine break-in or if the engine has not been used for a long period of time, engine oil will not be distributed to all of the operating parts.
Using the engine in this condition will lead to seizure.

After a long period of non-use, distribute engine oil to each part by cranking the engine.
Perform the following procedure before beginning operation:
1. Open the seacock.
2. Open the fuel cock.
3. Put the remote control shift lever in NEUTRAL.
4. Turn the battery switch to ON (if equipped).
5. Turn the key to ON
6. While pushing the STOP button on the control panel, turn the key to the START position (Figure 13, (4)).
NOTICE: NEVER hold the key in theSTART position for longer than 15 seconds or the starter motor will overheat.
7. When the key is in the START position, the engine will begin cranking.
Continue cranking for about 5 seconds and listen for abnormal noise during that time.
NOTICE: If the STOP button is released during the cranking procedure, the engine
will start. NEVER start the engine in this mode.

Dont crank too long... do it in 5 sec or so bursts. also, dont over do it or you might fill the exhaust with water.

Uh-oh .... in the future, HAND CRANK first ..... I really hope you turned it over a few times and let it set over night before you fired it up?

Follow the rest of the Yanmar break in procedure - 50 hours, you should run under a load.

But, first, I would run it light for a few revolutions and let it set 24 hours .... I gotta feeling you are past that step.

It probably sat in their warehouse for a year before you got it.

What exactly does turning it over by hand and letting it sit over night do? I figured turning it over by hand would wipe away any oil that was on the cylinder walls.

Also what direction do you turn the engine if looking at front of the engine?

Thanks

Re: New Engine Has Been Sitting A Year Ready to Start?

Replace the impeller? When I had my water pump rebuilt this last summer, they just sprayed a lubricant on it so it woulnt bind in the second or two before the water got to it.

Re: New Engine Has Been Sitting A Year Ready to Start?

On GordMay's instructions that came from Yanmar it states, "open the seacock." Don't keep it open and continue to crank if it doesn't start within within a short period of time. It will flood the engine with seawater if it does not fire soon.

Freerider. Each engine is different. Someone early in this thread said clockwise when looking at the crankshaft pulley (front of the engine).

kind regards,
