    Replacing Water Separating Filter on Optimax

    Don,

    I was looking to replace my water separating filter on my 03 225 Opti. Would you mind walking me through this procedure? Also if you give me a price quote on the parts I would need it would be much appreciated.

    Thanks,
    Nick

    -Remove cowling

    -With a flatblade screwdriver, CAREFULLY separate the TPS link arm from the TPS (you're disconnecting the ball and socket joint at the TPS). Set the arm out of the way.

    -Utilizing a 896661 Filter Removal Tool (or as an alternative, a screwdriver through the plastic tabs... be careful they can break), unscrew the filter COUNTER CLOCKWISE while looking from the TOP of the VST and remove the filter.

    -With a bright flashlight, look down inside the chamber. You'll need to drain any water present, and clean out any debris which might be sitting at the bottom. If you need to drain the chamber, use the "u-shaped" hose that's provided at the bottom. To drain, look at the FRONT/BOTTOM of the VST for an ALLEN SCREW or FLAT-SCREWDRIVER DRAIN SCREW (loosen screw several turns to allow draining). Retighten drain screw when finished.

    -Lightly lubricate BOTH o-rings on a NEW 8M0060041 filter with 2-4-C (or petroleum jelly/vaseline if 2-4-C is not available). Clean off any excess that is outside the o-ring area.

    -Install filter... turn it CLOCKWISE until firmly seated.

    -Using TWO FINGERS (or as an alternative, a pair of pliers), squeeze the ball and socket joint for the TPS link arm back together. Be careful not to "pry against" the TPS itself... this can damage the TPS unit (hence the recommendation of two fingers or a pair of pliers to squeeze it together).

    -Pump the primer bulb until it's FIRM.

    -Verify no fuel leaks present at VST or filter.

    -Project Complete.

    Is the same filter used for a 2005 Pro XS serial:1B162522? How do I identify the TPS (where is it).

    Should this process be done prior to putting it away for the winter or can it be done in the spring? I am storing in a heated garage.

    Also, could you send me a PM with the price for this?


    Thanks,
    Kent

    Same filter- same proceedure.

    If you were to loosen the filter.... and attempt to lift it out of the housing, you would be prevented from doing so by a metal linkage located directly above the filter. This linkage attaches at the "rear" or aft end to a black, square device.

    That black, square device is the TPS.

    Re: Replacing Water Separating Filter on Optimax (EuropeanAM)

    I'm confused.

    Read in another post Don said Mercury does not recommend water separators as they may affect fuel flow.

    I was going to have a water separator installed on my new rig but based on that did not.

    Mercury does not recommend the installation of ADDITIONAL filters.

    According to Mercury: "Your engine is already equipped with an adequate level of filtration".

    In your case.... there is a water separating filter UNDERNEATH the engine cowling. Yours, however, is different from the type described in this post.

    Re: Replacing Water Separating Filter on Optimax (EuropeanAM)

    Just got around to replacing mine last night. Thanks for posting the instrucitons, it was a very easy project with your instructions. Also thanks Don for reccomending the 896661 Filter Removal Tool, it would have been a major headache without it.

    The only step I didn't follow was the part about draining the water so I just sucked it out of there with a turkey baster

    Thanks!
