Force 50 hp 1985 gas/carb problem

[Zachtjohnson]

I have a 1985 50 hp Force outboard on a 16.5' Starcraft with a 6 gal. fuel tank. It will start but for me to put it in gear i have to revv up the engine in neutral then slam it in forward in which i take off but even with throttle all the way down the motor is bogging and won't get up to speed. I mean max speed is not even 2 mph i had about 2 gallons of fuel and i ran out of gas before i could turn around. So somehow i burned all 2 sogallons in about 3 mins?!?!?! how is that possible?? i checked my float and carb. and everything is clean!?!?!? i have spark and it will run it has some trouble idleing but it seems to be drowning itself. There is no apparent fuel leak but when i paddled back to the dock i saw alot of fuel sitting on top of the water. I'm lost and i don't know a whole lot and dont want to replace anything uneccessary. what do you suggest i do. Thank you for any knowledge and wisdom shared!!

When you prime the bulb does it get hard or stay hard? Cheapest starting point would be to replace the fuel pump diaphram. Iboats sells them the kit is 18-7806. Part number 4 and 7 would be the main parts in the kit you will want to replace
