Can I find maintenance instructions on the Internet without having to buy a manual?

make sure you put it in forward gear before you drop the lower unit. Makes it easier when you put it back together.

Check in the Library for a manual before you buy one. I went yesterday and found a manual that I could just copy the pages I needed instead of spending 30 bucks. I paid a little over 300 for my motor, wasn't to keen on a paying a tenth of that just for a manual.

phatmanmike, thaks for the advise. Manual, water pump impeller and fuel pump kit have been ordered.<br />this 9.8, at last accounts was runing OK until the fule pump cracked. It has been in a garage for several years and was given to me. I will use this is a extra motor when going down stream. It won't hurt to put a little money in it for safety.

In my experience, a manual often pays for itself very quickly...<br /><br />"Hmmm. How come this doodad over here won't come off? Arrrgh!! – CRACK!! – Oops. Oh. There's a bolt there. Now how was I supposed to know that bolt was there? "<br /><br />Time passes....<br /><br />"What do you mean a new casing is No Longer Available? I've already spent $600 on this thing and now I can't finish it because that casing isn't available?... Well, yeah, it was fine before I tapped it with a hammer trying to loosen it.... Well, okay, so the manual clearly illustrates the proper way to remove it? Oh, okay. I see. And removing that one bolt would have saved me from cracking the housing in the first place. Dang. Okay, so you're telling me I have $600 invested in a motor I can't use because I couldn't cough up $30 for a manual. Yeah, I guess I deserve that..."<br /><br /><br />Been there, done that and have the scars to prove it!!<br /><br />- Scott
