Running in a new outboard

Hi all
I want to run in my new outboard in a tank in the back garden, seems you need to put in twice the amount of oil for 10 hours run time, will this be ok or do I need to do it on the boat
Regards
Mick

you must keep the water cold, but look in the owners handbook, full instruction used to be in it.

Thanks for the temp tip, the hand book does not really say on or off the boat, the main difference I suppose will be that the motor will not be under load as it will be in a tank in neutral

I don't think that running it in in a tank is a good idea. As you have said it won't be under any appreciable load. It needs the load to allow the rings to be properly loaded up and form a seal with the bores.

Is it a new 2 stroke - you refer to more oil?

If it were me - i'd just get out there and use it. Gently for the first couple of hours. Vary the speed. No full throttle for a while. It's all in the handbook.

I would suggest that will be very bad for the motor to run it in like this. Running in engines should be done under normal (but not excessive) load, so that everything beds in properly. I know that running in a vehicle engine in this way would do it long term harm, and I can't imagine outboards are any different. I was once told that the rings etc would not bed in, bores would be glazed etc. Same with idling engines for long periods, especially when they are cold.

Nor will you be bedding the gearbox in, it's not just the engine.

Sounds like a couple of steady cruises down the river and get it done right
Thanks for all your help

Is this a craftily acquired Tohatsu 9.8?

Agree with all above you can't run an engine in using a tank at home. Assuming I'm right re engine type I bought one a few years back that looked so new I wasn't sure if it had been run for ten hours so to be sure went through the break in procedure.

If you read the manual after just 1hr you can go up to 3/4 throttle with 10% of the time at full throttle. So in truth that's pretty much a typical trip out with a SIB on the sea.

Running at a steady low speed on the river won't run it in fully and at near tickover speed the first 10hrs on 25:1 risks oiling up a bit.
