2005 Nantucket Fuel System

Does the Nantucket come with an external Fuel/Water separator filter? If not, should I have one installed? Taking delivery soon to splash the boat; however, the dealer owes me money (strange, eh?) and I wonder if I should have one installed before putting the boat in. The engine is a 2005 150-HP OptiMax. Any and all thoughts are welcome by this inaugural Whaler novice. Thank you.

The OptiMax engines do not require an external separator. I believe it has something to do with restricting fuel flow. These engines have an internal separator/filter that you usually change once a year.

Though Mercury says you don't need one, I've had Racor filters in front of a pair of Merc 135 OptiMax egines for 7 years with no problems whatsoever. You can find a Racor at almost any little outboard shop of any brand, or any marine chain store around the country whereas a Merc OptiMax separating filter might be a bit harder to come by. The added separator is only restrictive if the fuel flow is great enough for it to be a factor. On the 135 Opti, there is not enough flow to matter. The fuel burn for the 150 Opti is within 2GPH of the 135, so a Racor likley won't hurt a 150 either.

I wish to thank you both for your prompt response(s)...thinking of installing the [RACOR] as a redundant system. Thanks again.

Mine came from the whaler factory with the Racor filters in front of the Optis, so go figure. Maybe they did not read the manual either. BillS
