Re: L drive impeller replacement questions
I posted this in your other post as well.<br /><br /><br />As Bondo said... <br />You have a Bayliner boat<br />A Force powerhead from a 2 cycle Force outboard<br />And a Force L-Drive, part of which is also taken from a Force outboard.<br /><br />Its a bit of an extinct hybred.<br />Most shops won't work on them.<br />Very hard to find parts for the drive unit.<br />No other drive will hook up to the powerhead.<br />The ignition system is ..... fun.<br /><br />The muffs will not work for your unit, get a barrel or tank.<br />Even a big wooden shipping crate will work if you caulk the cracks.<br /><br />You can get a special waterhose attachment from Mercury for that motor, part number 819069T about $65 at any Mercury dealer.<br /><br />Sorry to bring you the bad news, but it will be a good learning project/experience.<br /><br />You need a good manual.<br />The Clymer Force repair manual is good.<br />Or look on ebay and see if you can find a factory L-drive manual.<br /><br />They made 3 models of your motor in 1990, a b and c. You have a "c" model, (the last letter in the model number).<br /><br />Here is a link for all the diagrams for your "c" model motor.<br /><br />mercruiserparts.com/Show_Pictures3.asp?dnbr=FOB4540&ivar=images/FORCE/FOB4540/33.png&inbr=1342&bnbr=150&bdesc=GEAR+HOUSING<br /><br />
<br /><br />You should replace the waterpump housing, gaskets, plate, and impeller, parts 10, 11, 12, 14, 15, 16 in the picture above. <br />You have to get these from a Mercury dealer, or a Mercury dealer online, like mercruiserparts.com <br />I think all these parts are included in the waterpump kit from Mercury, part number FK1204-1 WATER PUMP KIT<br /><br /><br />To change the waterpump and impeller, you need to remove the gear housing from the L-drive. Then you slide the old waterpump off of the driveshaft, and replace it with the new one. <br /><br />It is my understanding that only the 1992 model had an oil injection system. So you will need to mix oil with the gas as you put it in the gas tank. <br />50:1 50 parts gas, 1 part oil.<br />2.6 ounces of oil to 1 gallon of gas.<br /><br /><br /> So I believe the tank and pump you referred to is the tilt and trim pump, which is a hydrolic system to raise and lower the drive unit. Raised for trailering, lowered for use, raised SLIGHTLY for optimum performance. Here is a picture of the hydrolic trim pump and reservoir.<br />
<br /><br /><br />Anymore questions, feel free to ask?<br /><br />That's why we're here.
