I want to put synthetic oil in my outboard motor?

I bought a small outboard motor from a friend a 5 horse, power Honda, I need to change the oil and want to use synthetic oil,(I plan to keep it for a while)has anyone used it in a outboard motor? I'm an occasional boater i'm looking for pro's and con I guess thanks

Yep, use any synthetic 10W30 you choose. However, once you start to use synthetic, don't switch back to regular multigrade. Do your oil change with the engine warm, I believe the capacity is about 3/4 of a liter. Change your oil every 80 hours or once per year, whichever comes first. You should also check and change the gearcase oil by the same schedule.

Not going between synthetic oil and dino oil is a myth - the new synthetic oils are completely compatible with dino oil - change back and forth as you see fit.

Thanks I do have 3/4 of a liter of synthetic oil, I also use it in the car (synthetic oil) thanks again

i was told that synethetic was devopleted for turbo air planes because regerlar oil wouldnt hold up
