Hi- in response to your Yamaha engine request we have contact Crowley Marine (Thanks Colin) regarding if this kit contains an air fuel screw for adjustment on a 20 to 25hp engine. They have indicated it does.
I'm have a 1998 Yamaha outboard motor 115hp my serial number is 6E5X-5P3850 I'm looking for a complete rebuild kit for both carbs. Everything. Thanks.?
First we can only go off what Yamaha recommends for a rebuild kit. Second, we will have to go with the OEM option as Sierra does not make one, so we will need model number. Let us know if you can provide that.
