Questions on 25 hp Merc

Question

delmuts

bob. the lower units do take a special oil. you can get this at any marine dealer, some parts stores. etc. the prop sounds about right. on that size motor a 13 should give you a good balance of speed and power. this also depends on what size boat you have it on. i ran mine on a S16 lund and it did well. try it and see how it does. del

Hi Guys,

I just bought a (I am told) 1984 Mercury 25hp long shaft manual start outboard. I have no experience with Mercs and am wondering if anyone here can answer a couple of questions for me.

It has the shifter right in the tiller. I am wondering if the lower unit needs special gear lube?

I am also wondering about the prop. I am not sure what it has on it (I am at work at the moment), but it came with an extra prop that is a 10 1/4 X 13. Does anyone know if this is a power prop or if it is a speed prop?

Thanks
