Engine starts then runs ok for 30sec to 1 min then starts to sputter and dies.
Wait 2-3 minutes and restart with same thing happening
Cleaned carb checked jets and passages
checked filter ,fuel pump
when I loosen the Electo thermal valve runs for a little while longer and dies again
Thinking it...
Want to convert 1992 yamaha 9.9 to 15 hp if possible
I can not find a 15 carb for that year
Can I modify a 9.9 carb to make it run like a 15 hp
If so what drill sizes would work to make the modification to the jets.
Do I need another intake manifold or would the 9.9 suffice.

This thing is still driving me nuts---------------- 0T008360 ser #<br />I'm getting low oil pressure at idle and 1500-2000rpm.<br />At idle my tee'd in pressure gauge shows Zero<br />At full throttle 30-35 lbs<br />I removed the pump and inspected it.<br />It is on the bottom of the camshaft...
I have a 2000 Merc 4 stroke 50 hp bigfoot.<br />Serial # 0T008360<br />Model # 1-F50452Wd<br /> 50ELPT-4S<br />I keep getting an alarm after a 5- 10 minute run after I throttle down in about 30 seconds to trolling speed just barely above idle.<br />I have a good water stream as in the past...
