The following is from a Basser forum, this guy really knows his stuff on Mercurys: This list will be updated as additional information is requested- check it regularly for the most current information! Oil: -These are the 'top recommendations'. Refer to your owner's manual for other oil specifications! -ALL EFI/CARB 3.0L Engines: Mercury or Quicksilver Premium PLUS -All STANDARD Optimax (75-250): Mercury or Quicksilver DFI/Optimax Oil -ALL ProXS Models: Optimax/DFI Oil. Mercury or Quicksilver Premium PLUS is acceptable, but Optimax/DFI oil is RECOMMENDED due to a better additive package to help combat carbon deposits.ALL Racing/XS Models: PREMIUM PLUS - (Note. There was some conflicting information on Merc's Website- follow this recommendation for the latest information as it's released!) Battery: -MINIMUM 800CCA or 1000 MCA Capacity. More is better!
Use Stainless Steel Lock nuts (don't use wing-nuts).IF you have a lot of accessories you are running, KEEP IN MIND that this specification is for the ENGINE CRANKING BATTERY. You may need to INCREASE the battery specification to provide adequate cranking capacity based on your accessories being run!

Mercury 250 Pro Xs Service Manual
200 ProXS Models manufactured AFTER 2/1/12 (Serial Number 1B912786 and later) will utilize IZFR6J (gapped at.042.044') due to production changes in the engines.IZFR7M for 300XS:.044' Gap FUEL: -All models- MAXIMUM ETHANOL CONTENT: 10%. Ethanol content may adversly affect engine performance.See 'Mercury's View of Ethanol' on Sherm's board at: -Standard Opti's (ALL) 87 Octane MINIMUM.XS, XB or Racing PRIOR to 2006- CONSULT OWNER'S MANUAL! Most require High-Test! -ProXS and 250XS 2006-later: 87 Octane MINIMUM. Idle quality may improve with 89 Octane (mid-grade).300XS- Consult Owner's Manual. High Grade (minimum 91 Octane) fuel required!
Fuel Additive Recommendations: -Stabilize fuel ANYTIME fuel will not be consumed and replaced within 15 days!!! -Optis (ALL, including XS & ProXS): Quickleen in EVERY TANK OF FUEL.
You CAN combine Mercury QuickCare or QuickStor Fuel System Treatment & Stabilizer (or Sea-Foam if you prefer it) with Quickleen. Use the recommended 'dose' of each product per the bottle instructions. For anyone questioning Quickleen recommendation- see Service Bulletin 2001-12 (yes, it's been recommended since 2001!!!).Quickleen may be used in ANY Mercury engine- it helps to prevent/remove carbon buildup (primary purpose). 'Mercury Component Cocktail' (Chemically, this works much the same as the previously recommended (and now to avoid alcohol content) cocktail, and requires less components.) This is Don's Preferred 'Cocktail': -1oz Mercury QuickCare per 5 gallons fuel -1oz Mercury QuickLeen per 5 gallons fuel (If leaving fuel in boat for more than 30 days, be sure to also add Mercury QuickStor). Fuel/Air Pressures (Optimax): Two different pressure differentials are used: -75-115 3 cyl. And ALL XS Racing & 225-250 ProXS Motors (And the 250 Optimax) use 94/108 Air/Fuel Pressures (Fuel pressure equals air pressure + 15psi) -All other 'standard' Opti's use 80/90 Air/Fuel Pressures (Fuel pressure equals air pressure + 10psi) -IF YOU HAVE NO AIR PRESSURE- YOU HAVE LITTLE OR NO FUEL PRESSURE.
The fuel pressure is DIRECTLY relative to the AIR PRESSURE! So- if you have low or no fuel pressure, CHECK the air pressure, and check for AIR LEAKS before you start replacing fuel pumps!. Neat little 'rule of thumb': If it has 'gray' Direct injectors, Air/Fuel is 94/108 and it uses a spark plug that 'ends in J or M'. (one motor exception- it had black injectors with a 'white dot'- consider those to be 'gray'). If the direct injectors are Black, Black with a Blue Dot, or Blue, the Air/Fuel is 80/90 and the spark plug probably ends with a 'G'.
2010 Mercury 250 Pro Xs Service Manual
Use only DFI/Opti oil. Merc changed the reccomendations to exclude Premium Plus / TCW3 oil on all Optimax and Pro XS motors ( unless you're out and that's all that's available.
Go back to DFI oil as soon as possible). I believe that this has to do with the occurance of sooting with alot of idling as done with fishing. The Pro XS motors originally reccomended Premium Plus oil but were usually run on 'Go Fast' boats that did not idle for long periods. Now most bass boat come equiped with Pros and half of their run time is below 2000 rpms. With spark plugs costing $20ish+ ea, I'd want them to last as long as possible.
