SOURCE: need to install water pump in a 87 lowe pontoon

The water pump is in the leg, you must disconnect the gear linkage and undo the bolts that hold the bottom of the leg in place( pointing up above water intake). Dont forget the one near the propeller. Wiggle the leg and slide downwards. place the leg on the bench , the drive shaft protrudes from the center of the water pump housing. Undo the bolts holding the housing on, and slide it off. Be sure to install the new impeller with the rotors folded in the correct direction to avoid pinching. when re installing the leg be sure to align the water cooling pipes correctly. It is always a good idea to refer to a workshop manual when attempting any maintenance upon machinery.

Cheers, Timo.

Tip

Changing oil in lower unit on an outboard motor.


the oil in the lower gear case in a outboard motor should be changed every fall when you take the boat out or once a year if you live where you can boat all year. when you look at the lower unit down by the propeller you will find two screws one lower and one upper. take the upper one out first and check the nylon gasket and replace if worn. put a coffee can or and oil collector under the moter and take out the lower plug. if possible do this after the moter has been run recently, but never run an outboard out of the water unless you have the garden house hooked up to ear muffs over the water intake sites!
the oil will slowly drain out. if the oil looks like chocolate milk it probably has water in it which means its leaking at the upper or lower seals and needs a pressure check and possibly seal replacemant. after all the oil is out (30 minutes or so) its time to refill it. for less than ten bucks you can but a simple device that lets you pump the oil in instead of squezzing it out of the tube. you attach it to the lower drain plug hole and the to a quart of the proper fluid for your motor. make sure you buy the oil to match your type of outboard.
pump the oil or squeze it it from the bottom until it starts to come out the top hole. make sure all the bubbles are out then put the upper plug back in with good gasket, remove the oil tube or appicator from the bottom hole and quickly relace the bottom plug as well with a good gasket.
thats it and you are good to go for the season. if you see oil leaking out the prop shaft or at one of the plugs you need to attend to that soon. tip remember chocolate milk oil or actual water means a seal leak and must be repaired.it may just be a .25 nylon seal for one of the plugs is bad! any unusual noises of difficult or loud shifting can also means problems with the lower unit gears etc and its always cheaper to fix the problem sooner than later.
happy boating!!!!!!!!!!!!

I have a Mercury Verado 250 HP 2005. The problem is an oil loss. The only thing i am sure of it is engine oil and despite it was verified by Mercury dealer twice, they didn't find where it con


how many miles are on the car. it is normal for a care with a 100k or more to use a qt of oil about every 1500 to 2000 miles if you keep your foot in it. read your owners manual about how often you should check your oil. it is more often than you would think. think about using an oil additive that helps reduce oil consumption.

the seal around the drive shaft is leaking ---split the leg and replace or the seal behind the prop is leaking -- remove the prop and replace I would go for the drive shaft seal as it is under pressure from the water pump.

Oil leak front engine timing chan


1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

1973 6hp Johnson- How much oil does it take for the lower unit, and what type of oil is recommended?


It takes less than 1 litre.You buy it in 1 litre bottles.Go to any boat shop and ask for gearbox oil.There is 2 screws to remove and they have a washer on each.Replace them also.The oil is put into the lower hole untill it starts to come out the top hole.You then quicly put the screws in.The oil container comes with a taped nozzle to do this and its a squeeze bottle..Also a good time to take the prop off and check for fishing line etc. that can damage the seals and to also grease the prop shaft.Hope this helps
