I have a 70hp Johnson 2 stroke, my problem is it is hard to start but when I get it running it runs out great. After I stop and fish for a while it's hard to start again, after I get it running it runs out great. It will start and quit for a few times before it takes off. Thanks
 
Step #1 is a compression test.----Post the numbers.----Are you pushing the key in and holding it in while starting it ?---Charged the battery and had it load tested ?------Does tell tale hose come off the side of the block or has it been moved to the top of the block ?-----I suggest installing the lates water pump kit.----
 
Thanks Have not had a compression test. I do hold key in while starting. Had water pump installed last year. Had new fuel tank and fuel lines last year. Don't know what the tell tale hose is.
 
That doesn't mean that it's pumping enough all the way thru enough to cool it. If the impeller hasn't been changed in the last 4 or 5 yrs It needs to be changed. Nvm I see that you changed it last year.
