    I have a Mercury 650 Thunderbolt serial# 2206852 , took it out today for 1st time w/fresh oil in it and got home and drained a milkshake from it and put fresh back in it...the guy I just bought it from said he just put a water pump kit in it(himself)and gave me an extra water pump kit also new in box w/orings and such ...what seals needs to be done and can I do it? I don't have a manual , can I use it tomorrow for a short haul to my fav fishing spot?If I have to take it to the shop about how much do you think it will cost?Thanks

    What I would do is take the fill and drain screw out and take those fiber washers that are in behind them and go to a local marine shop and purchase new ones and replace them and then try again.
    That is the most often overlooked gaskets that need to be replaced about every two years that I have ever encountered.

    I have seen guys replace every seal in a lower unit and leave the old drain and fill screw gaskets in and wonder where they messed up.

    If you need to go tomorrow refill with new oil and go and enjoy but don't venture to far and it should be okay.

    In the mallory water pump kit there is 2 fiber washers not real wide but I don't have a parts list of them in the kit so don't know if that is what they are for

    They could be white or clear looking plastic. They won't be on the screws they will be in the little round holes that the screws are recessed in. I take a small sharp pointed pick or knife blade and pop them out. They also don't come with a water pump set either. Thats a counter part and aren't very expenseve so get two sets when you go get some.

    Take one and see if it will fit over the screws and inside the recessed place. They make a snug fit on the screws and in the recessed hole to.

    I would appreciate it , I called shop today and they quoted $250 , said a special tool is needed and named all of these seals that needed to be replaced , if it costs that much I am done fishing until Spring as lay off is coming fast and a tight budget follows and no extras for boat....I would pay someone around here to help me do it if they know how...

    Where do you live at in tenn roy. They are assuming that you need all seals including prop seal. If it doesn't get any more water in it after replaceing the screw seals then no worry. If it gets a little them most likely its the shift shaft seal which is no biggie.

    You can take that lower unit off and pressure test it to find out where she is leaking and then the guessing is gone. Easy to do and won't cost much to do it.
    I am about 85 miles south east of nashville and if you want to bring it over sometimes I'll be more then glad to help you do it. Or you can do it at home and I'll talk you right through it.

    Set it in a can of water with the lower unit surmerged below where the shift shaft and water pump set on it and either get a fitting that will screw into the fill hole and apply air to it. Not over 10 or 12 pounds of pressure. In a pinch I have taken a rubber valve stem that goes in a car wheel and held it tight against the hole and applied air. The seal that leaks will have air bubbles comming up around it and that is why you don't want a hole lot of air to it. To much and it will rupture the good seals.

    well I did break down last week and had it done .I found a guy that works for a shop during the day and has his own repair shop at nights and weekends. $195 for all seals , water pump , oil , labor and he put it back on at 10PM when I was having problems with the shift shaft .Just so we could go fishing the next morning with the kids. If anyone in the Clarksville area needs professional help let me know , I would recomend him to anyone.He had it done in 3 days and was about $100 cheaper than anyone in town. Very polite and looked forward to my business , which now a days to not be a number was really nice...just thought I would let ya'll know ..Thanks bubbacat for everything
