ok so my buddy asked me to do the water pump in his 50hp he says its a 74 but he just bought it lol it looks like early to mid 70's it has the 3 piece motor cover and its a thuinderbolt ign. so heres my problem once i had had all the bolts out even the one hiding under the zinc the drive will only seperate a half inch or so i thought the shift rod would just drop like on many others that i have done so then i looked under the carb thinking i had to disconnect there like many of the johnsons but all i see is the shift arm and the linkage but there held together with a roll pin? any ideas im not often defeated by inanimate object lol thank you ahead of time
