Thank you guys for the information! Like I said there is definitely a learning curve with the Merc vs the omc stuff I am used to.

Last night I had some success in disassembling the lower unit. I was able to pull the cartridge out and then the prop shaft and bearing. The thing that actually fought me the most was the gear on the end of the drive shaft was stuck on there pretty good but after a while I got it to pop loose. I can now clean and service everything before putting it back together. This gear case along with the rest of the motor is in great shape I just want to do it right and service everything while I am in there. I find it interesting the different approaches that the different companies used when designing a motor. Being an engineer myself I can kind of see into the designers head a bit when going through a motor like this.

Now my next question is about the water jackets. I haven’t planed on pulling the cylinders because the compression is good (both in the mid 90s) but I dont see an easy way to clean off the rust and scaling from the outside of the cylinder heads and the inside of the water jackets without removing them. Does anyone have any suggestions for me on how to go about getting all of that crap out of there while keeping the crankcase together? If I have to take the heads off I would go ahead and hone it and put new rings in but if I can avoid it I would like to.

Thank you all again for you help
