Hard to start yamaha 115

[4InAROWE]

Can anybody help me with a starting issue on 1992 115 Yamaha. Starts strong and instant in the driveway when flushing out out the end of the day but when I'm in the saltwater creek / river it's very hard to crank. I have water separator on, bulb pumped up,,,,what can I do? Need reliabilty.Thanks for help.

time to give it a tune up
change plugs
rebuild carbs
replace fuel pumps to be safe

Did your boat set up for any length of time?

post your exact step by step blow by blow starting procedure, only difference between a driveway start and a water start is exhaust back pressure and improper starting proceudure will make it worse.
