60hp Johnson vro stalls under load

[crhm8]

Hey I just bought a boat 1987 boat with a 60hp vro Johnson and out of the water seems to run good but lower the motor into the water and it dies kinda seems like it might be flooding looking for an idea where to start

I always do a compression test first.----Do you know the history of the motor ?

 

[crhm8]

From what the guy I bought it off says is it got rebuilt about 20 engine hrs ago and has sat in storage for the last year

 

[crhm8]

I’ve checked compression I have 110 on top 110 middle and 115 bottom

Now open air gap spark test set to 7/16" with the appropriate tester.

Think I figured it out pretty sure the coil to the Center cylinder is week

 

[crhm8]

So I found a bad coil and a bad wire fixed that and now I can get it to work but I have to choke the motor as I take off until it finally planes out once it plains out and is at full speed it runs good but if you slow down it has no get up and go and have to choke it again until it planes out again
