Mega Newbie Question on a Johnson 150

[JBozeman]

Maybe this is where I should have put my other questions! My bad if the other is in the wrong location.


<HR style="BACKGROUND-COLOR: #fff; COLOR: #fff" SIZE=1><!-- / icon and title -->Bordering upon mega Newbie question so don't laugh to loud!

Some of you will have read about my New to Me rig that is loaded with a 1998 Johnson 150 FastStrike. As I have been going through the process of getting it ready for the water in a few weeks I am well pleased with what is working, batteries, Trim, Trolling Motor, Depth Finder, bildge pump etc!

However in starting to give the motor some attention I came across something as a bit of a surprise to me! When I put the hose fitting on the water intakes on the lower unit and turned on the hose, the water being expelled out of the lower unit was really close to the intake ports. I have always been used to being able to see if the water pump was working by water being expelled higher up on the motor. If the water pump expells water below the water level and it not visible, that is a bit uncomfortable. The water temp guages on the dash are extremely important if this is the case.

A manual for this motor seems to be rare thing!

I have not tried to crank the motor yet as I plan to change the lower unit lube before I do that!

Anyway, thanks for any help with this Newbie question!

when having the cuffs on the motor. water will leak out an all lower ports below the water going in. so yes the lower unit intake ports will leak some.

My bad Jester on the wrong location!


Concering the water ejection ports, I was expecting to see water being expelled up close to the cowling level not so far down on the lower unit!

Thanks guys

Once the motor cranks & is idling you will see a pretty good stream from the pee hole & it will also pour out from the prop hub unless the water pump blades are completely gone .... but... until motor is actually in the water it is normal to have water leaks all over the lower unit while attached to water muffs.

Thanks 4! I guess what I should have asked was, where is the pee hole located on that model? The only port or pee hole seems to be really close to the water intake ports. Really good stream comes from that hole, just "leaking" from other places. I was just used to the hole being much higher as on the old mercs I used to run.

Thanks my friend!

The tell tale is located directly under the motor cover on the rear of the motor. It is in the dead center of the lower motor covers. It WILL not discharge any water until the motor is started. Water will however also come out the seam between the lower unit and the mid section. If the water flow is not noticed then you can use a 13/16" socket (spark plug wrench) and remove the nut. Some debris may be in the opening for the discharge. It is OK to run the motor with this off.

Thanks to all of you for your help with the Newbie question. The port can even be adjusted to right or left angles so you can have the best visiblity to notice the out put from the pump is functioning! Thanks again folks for your very benificial help. I feel a lot more comfortable now knowing what is going on with the water pump while under power as opposed to having to depend on a temp guage.

Take Care Y'all

It is best to adjust it so the flow comes out on the driver's side. A water pressure gauge would be a very nice add on item if your boat doesn't have one. It is the easiest way to monitor your water pump's performance.
