I have a 1986 Johnson 200 GT (JSTLCDR200) on my Ranger 391V.

My question is, where do the intermediate jets take over from the low/idle jets?

My boat idles around 700 RPM, and when I gas it, it jumps to 1600 RPMs, and then it plows and bogs and SLLLLLLLLLLLLLOWLY climbs. When it hits 2100 RPMs it gets up and jumps on pad, but its like a 15-20 second hole shot, which should not be happening.

So, which needs to be adjusted, to give me the fuel to get up?

Also, what is involved in adjusting the jet? Can i do it myself?

Thank you.
