Car engine oil would be fine. I'd put a socket on the flywheel and gently wind it over by hand after leaving the oil to soak for a few hours. If a ring is sticking slightly then whizzing it over by key could snap it. If you do wind it over by key don't have anyone stood behind it as they'll get splattered in oil, unless you want a laugh.

Take care not to put too much oil into the cylinders or you might hydraulic it. I wouldn't imagine there would be more that approx. 20ml space at TDC.

Given that you say it turns over ok at present and you are going to get it serviced shortly, why bother?

What Would Happen If I Put To Much Oil In Each Chamber But Still Left Spark Plugs Out Then Turned It Over

Nothing major-you'll get a lot of oil in the bottom of your engine cowling and the plugs will oil up when you try and start it as some will find it's way into the crankcase.

If it were mine and it was turning freely, I'd just start it up.
After giving it water, of course.

After 5 years standing it's worth oiling the bores first. Any tiny specs of rust/crap in them isn't going to do it any good being turned over at speed while dry before it starts.

'give it water' means running it on flush muffs so it doesn't frag the impeller. If you start it without water it'll kill the impeller in seconds.

for Fkks safe don't mention muff It'll give Mike entirely the wrong idea!

If you don't have any m***s they are also known as Headphones just put the bottom of the engine in a clean dustbin of water or something big enough to get the bottom part of the shaft in.

Just in case this is your first time then motor has to be secured to somethin. A transom is good for this sort of thing.

Do you know what a tell tale is?

It aint me



you mentioned the impellor earlier. The impeller is in the lower part of the leg and is part ( well most ) of the water circulation pump and it pushes the cooling water around the engine. The warm water is ejected from an opening near the botton of the engine usually in a stream

It's also referred to as a piss pipe as the two look very similar. If you don't have a tell tale after say 20 seconds then your water isn't circulating or the vent is blocked and your engine is on the way to overheating!

Pisser / tell tale

Flush muffs are available from any gd local chandlery, and connect directly to the hose. Alternatively an old dustbin or water but works equally as well, but make sure the water level is well above the cavitation plate.

Maybe but maybe not. Just to confuse the issue... The Merc I had didn't give a proper skoosh until the thermostats had opened. Strange system.

Put your hand on the cylinder head when it's running. You'll soon tell if it's getting hot quickly. If all is well, it takes a while. Keep yer fingers away from the flywheel!

Oh this is good stuff!!

Hi Mike,

Just repeating what everyone said:

Get flush muffs or a bucket of water before you ever attempt to start the motor. The muffs hook up to a standard garden hose. You put the muffs on the water intake of the lower unit. Be sure to fully cover the intake ports. Before starting the motor and turn the hose on full blast. This will help ensure the motor gets water circulating. If you crank the motor or run the motor without water 2 bad things will happen. First the impeller (rubber water pump) will burn up and may break apart. And two, the motor will very quickly overheat and self destruct.

If you use a bucket of water (most likely a large trash bin) you will need to make sure the motor is covered up a few inches above the anti-ventilation plate, thats the horizontal fairings on the lower unit. You might also want to make sure that you constantly have water in the bucket as the water level will go down as your running the motor.

After you've started the motor you need to see a pee stream of water coming out of the top part. This is a water flow indicator. If it isn't flowing it could mean 1 or possibly 2 things. First it could mean that the motor isn't getting the water flowing through to cool it. If this is the case immediately shut it down. Or the 2nd could mean that the pee stream indicator could be plugged but the motor is possibly getting the water coolant. The pee indicator in most cases is just that, an indicator. Its not necessarily the definitive that the motor is or isn't getting the right flow of water. One of the definitive indicators that a motor is overheating is if the head gets too hot to touch. If you can put a finger or palm on the head of the motor and its more than warm but not too hot to touch you're probably ok. If it gets hot like boiling water off hot, its definitely overheating if not already overheated.

When I get a new motor the first things I inspect are the impeller, thermostat, visual inspection of pistons through spark hole, compression, and leak down test on each piston. You should definitely replace the impeller first thing before even attempting to start the motor. Impellers are supposed to be replaced every year or at most every 2 (at least thats what I've been told). Its a high wear item.

Well if you really want to understand your motor or DIY, the best thing is to get a repair manual and flip through it.

Just some of my $0.02

By the way Mike, your particular motor doesn't have a thermostat-they never did have.
