Will be coming up on my 20 hour service on my 2023 sho 200. What should I be replacing at that interval? I plan on doing the engine oil, filter and lower unit oil. I see some kits online that also include like the fuel water separator and fuel filter. Is that part necessary as well? Would you use 10w30 or 5w30? I probably only put on 25-30 hours a year and never fish below freezing. I change the fluids yearly as well
