1987 mariner 45hp??????

[Snake River King]

hello fellas I bought a 1987 bass tracker with a 1987 mariner 45hp motor and the boat and motor have been sitting for 4 years. I went to start up the motor in a water tank to see how it was going to run and it fired up but I notice there was no water coming out so I ran it for about 1 min and shut it off do I have a bad water pump? is there a thermostat in it? or can mice get in there? your advice is greatly appresiated thanks SNK

I owned that exact model motor for over 10 years. It should kick water out the discharge a few seconds after you start it. If mine had a thermostat, it was stuck open. You probably need an impeller.

Don't take a chance, that is a nice motor, replace the impeller and you'll be happy you did.

[Snake River King]

thanks guys I think I will do that and change out the impeller. How much do you think a shop would charge to do the work?

[Valv]

Around here they charge form $ 100 to $ 200 depending on motor size (not much difference anyway), the water pump kit (with impeller, gaskets, wear plates, etc) should cost around $ 45, the impeller itself about $ 20.00

Impeller might cost a tad more if the outboard is the Japanese version that was first made by Mariner when they came out. I have an 88 40hp Mariner I changed out the impeller a few years ago and we had to special order. If the engine has sat for awhile you might also have an air lock. But that will clear when you install a new impeller. Good to do for piece of mind.

I just did the water pump impeller on my 89 Mariner 40 hp for less than $25 supreme marine had it in stock took me less than half hr to do it so i would say relpace it ASAP

If you guys don't mind me stealing the thread a bit but just last night my stream was plugged with some weeds etc. and with just a fish hook or stick I got it unlodged. But I have noticed it could be a little stronger. Plus I have had the boat for about 6+ years and I don't think the impeller has been replaced.

So my question is how do you replace one and where do you start? It's a 92 Mariner 115hp?

thanks,

mr

you have to take the lower unit totally off and the water pump is right on top of the lower unit.

If you go and get the part, ask them to print out a schematic, I am sure they will, our dealer did for us. The first time you do it, it might be tricky, but after that it will be a piece of cake. An extra set of hands helps tons, so keep them handy

Be sure to test it after doing it, as my first time I did not get the tube into the right opening, and had to try again.
