Thanks for looking out for me. thing is i need to find out what will fit, most of the ones i have looked at, look like they all would fit. my outboard is a 2004 model so not sure if the older blue band would fit. i think i will give a few outboard engineering shops a call and see if someone has the knowledge and can tell me the same outboard gearboxes that will fit from different models of mariner/mercury outboards.
big big thanks for your help and i post up what i can find out.
ps same to all the rest of you's for your help and advice, big thanks
