Hi, I have a 1986 Evinrude 50 HP 2 cyl with VRO. It still has the original water pump and I figure its time to replace it. I have a Selco manual and all it says to remove the shift linkage is to take the bolt out under the carbs. I have lossened the bolt but the shaft will not come off. I expect I must have to actually remove the bolt. Are there any tips on how to dissconnect this? Do I need to remove the carbs and or VRO unit? Once dissconected from the shaft will the part that has the bolt in it be able to slide out when I remove the lower unit? How bout what gear should I be in? Any tips for assemly would be helpfull to.
