Beside this, how often should you change oil in a Yamaha 4 stroke outboard?
For a 4-Stroke Yamaha, the required oil change, after the initial 10 hr. service, is 100 hrs, confirmed by a Yamaha Master Technician (one of only two in the state).
Likewise, how many hours can you get out of a 4 stroke outboard? Lower units anywhere from 3,000-5,000 hours, depends on use and how heavy boat is. Powerhead life all depends on maintenance and how it's operated. Most of the time it's the elements/corrosion that take them out before failure at powerhead. 1000 hrs will hurt the value of the engines.
Also to know is, can you use car oil in a 4 stroke outboard?
Yes you can use motor oil in your 4 stroke as was stated. However True Marine 4 stroke oils have additives to help prevent rusting. Here is what Amsoil has to say about their Marine grade Synthetic oil. And yes it is approved by NMMA, API and FC-W testing as well as all Outboard manufacturers.
