Would like to know how hard it would be to change my water pump. Is thier any thing special that I need to know about removing the bottom out drive, should it be in gear or netural,etc. Any input from you guys would be greatly appreciated. I just purchased the service manual but it dosen't have any thing about the out drive in the manual. Do any of you know what good manual I should buy. Thanks
If you have the OEM ser man part # 520211, you're correct. The g/c is not in there. What you'll need is OEM ser man part # 520210. You could also try a Seloc but I've never used one as I've heard they're no good.
Wild Bill, I have a '98 johnson 150 OceanRunner and the OEM manual #520210 mentioned by another poster. I assume the basic information would also apply to the FICHT engine but I am not certain. Anyway, here is the gearcase removal procedure from the manual.
Let me know if you need any additional info. GearcaseServicing
I just did this exact same motor for a friend of mine. We had "a lot" of trouble getting the shift linkage to disengage from the pin. There just wasn't enough movement to the port side to disengage the pin. We ended up just taking the aluminum V clamp off the shift rod linkage. (You MUST remove the locking bolt to get this thing off the shift linkage). It was a real PIA!
Also, be sure to get the key facing in the right direction when you put the pump down on the shaft. Check this BEFORE you put the lower unit back on the motor and have find out the hard way To check it, remove (or don't yet assemble) the top part of the water pump that slides over the main shaft attaches with the two flat blade screws. Once the pump is on the shaft (with this "cover" off), turn the prop shaft so the main drive shaft turns clockwise and look down into the pump. There's a small slot in the stainless cup where you can view the impeller rotating as you turn the shaft. If the impeller doesn't turn, you didn't get the key right.
