Hello Guys,
1977 Johnson ? 115 - 115EL77S - Ranger Fish and Play
I am sure you have covered this topic, but I cant seem to find any posts about this so far (I am sure this is just one of those things I should know, but I am not very mechanically inclined)
Basic Question: I got my new waterpump out of the box and I expected it to have 2 inlet/outlet tubes, but appears only to have an outlet tube.
Long version.
I had wear on my impeller and decided to replace my waterpump assembly. I ordered the part from here at iboats, and when the package arrived last night I headed straight for the shop. As soon as I opened the box I hit my stumbling block
So my original waterpump housing had 2 inlet/outlet tubes, and this new one has only one.
I checked to make sure I had ordered the right part. The housing matches up perfectly and the box says its the waterpump kit for my year (1977) so this caused me some concern.
However, I have thought the situation out (again keeping in mind I am a **** poor mechanic) but it seems to me that the impeller will drive cool water into the engine, and the other tube is the discharge.
So assuming I have that flow correct, with the new pump the tube running from the waterpump housing should match up with the tube I have labled "inlet?" in my image above. The outlet will then dump the warm water on to the top of the waterpump housing allowing an amount to be recurculated into the bottom feed of the waterpump housing and the rest through the small hole in the lower unit?
The idea of dumping water in the cavity between my upper and lower unit seems a bit counter intuitive. I am afraid I am missing something here. The idea of pourning water basically on my waterpump assembly (and potentially my drive shaft just seems a little odd) Do I need to convert to some form of 2 hose system, or is my diagnosis correct that this is the new "improved" design the SELOC manual goes on about and is designed to work this way?
final product:
I decided that the logic seems sound so I mounted the new pump, but before I try to put upper and lower units back together I wanted to run this past you guys.
Thanks for any advice.
Roy
