Which oil in SHO engine?

[Alesi]

It is good to run a motul 7100 10w60 oil in SHO engine?

[HydroStream6]

Most people run the OEM Yamaha or Amsoil.

If you live in the United States, or any country where Amsoil is available, I'd opt for their Marine 10W-40 formulation. Hands down, best in the industry.

No need for 60 grade lubricant in the SHO. This is the Motul formulation you need, if that's what is available in your area.

Oil choice is a polarizing topic here on GH. I always have used Yamaha 10w-30 on my FZR (sho engine) and I think it is hands down the best choice for stock/ lightly modded skis. If you're running some high performance setup, it is worth considering other options, but IMO yamaha is the way to go on 90% of applications.

10w-60 is to thick for that ski. If you want to use the Motul product use the Powerjet 4T 10w-40 Here is some information on the AMSOIL Synthetic 10W-40 Marine Oil that other people here are using.

The last time I called RP they said the HPS has more ZDDP. That is what is important, I change every 10 hours regardless.

The quantity of Zinc content alone does not indicate an oils performance. Therefore, it cannot be assumed that oils with higher concentrations of Zinc will provide better wear protection.

Here is some good information on testing of oils.
