Did you lose it or can it be repaired?

did you take off the top, cover.? and see if the flywheel turns easy by hand, key in other hand? my Mercury can be rope stated at the flywheel. (make up a rope starter cord or buy one) ? we keep one on hand. that clicking sound is the starter failing 99% is dead battery, caused, A starter uses 10 times more current than accessors, so we use car battery known good and test the starter that way, and make sure the battery connectors are not rusty.(aka: corroded) 1: battery no good. or 2 connectors to it rusty. 2 starter bad or the solenoid that drives it. 3: engine seized.

K. All outboards from the 1980's out have a built in kill switch. The most common problem for your issue is the shifter cable ( the one that puts you into forward ,neutral, or reverse) is stretched and you are not quite in neutral and are tripping the built in kill switch. Depending on the engine you will either not have anything happening when you turn the key or you will have zero spark or both. It is there to keep you from flying off the boat if you leave it in gear and forget. ... the second is corroded ground or loose ground on the engine or the battery. And third is a blown fuse at the engine end. To check if the problem is your shifter cable , just detach it from the engine and manually place it in neutral by grabbing the shift leaver located on the motor then try starting it again. If thats the issue then adjust the cable and order a new one and have it on stand by.. Throttle cable also. Both usually need to be replaced at the same time.

need your serial number please

Turn the carburetor upside down. The float should be level with the bottom of the carburetor.

First make sure the battery is working properly.If it will take a charge from a different charger then your charging system on the motor is not working and needs to be checked out. This is something the average person can not do.

you need to get a manual for that model I suspect that the hose to the unit on the block is the tank hose to the fuel pump and there should be a hose from that unit ( fuel pump ) to the carby the hose from the crankcase is possibly the hose that works from the pulses of the piston ( suction/ pressure ) that works the pump diaphragm to pump the fuel If you are getting fuel into the sump I would suspect a hole in that diaphragm discuss the problem with a service center for that make
