Hi

How can i find the correct jet configuration for my engine
mariner 175hp V6 1988 serial 0B252046

i've look at my main jet
this is what i have
0.74 0.74
0.64 0.64
0.64 0.66

dosent match anything from the chart

when i look at the schematics with the serial number should be 6x 0.74 or 5x 0.64 +1x 0.66

very confused

thank you

i did not removed them yet just remover the plug to empty the carb to see if there was presence of water

i have problem getting full power there is hole and sometime it goes then hole again

carb seem good at first look
 
Everything I see online shows the 175 HP as needing the .066 in all carbs. I know sometimes, when a motor is bored out and oversized pistons are installed, some builders will move up to a slightly larger jet. I'd order 6 of those jets. They're available on multiple websites. Part number 1399-4215
 
No dont order yet as you need to know is it a 2L 175 or a 2.4L? The 2L will use the smaller jets. Post a pic of intake and head. Bore size is cast on head unless someone tried to hop up and put 2L head on a 2.4L. The number will be stamped into carb: example WH-27.
