85 HP Carburator

[chuckz]

I have two sets of carbs for my engine one set is part number F631061 the other F831061. Are these carbs interchangeable?<br /><br />The application is a 1987 85HP.

Re: 85 HP Carburator

I entered both of your numbers into the mercurypartsexpress site and the response was the same for both.<br /><br />"Part number 803921T is no longer available."<br /><br />Another site listed the F631061 part number, so this may have been the original number, superceded by the F831061, which was superceded by the 803921T, which is now discontinued.<br /><br />I would venture to say they will work, but may not be interchangable, jetting may be different.<br /><br />I know, kind of a half answer.

At mercruiserparts dot com 631061 comes back as 1300-803921T and 831061 comes back as 1300-803920T.<br /><br />631061 I removed from the engine. 831061 I bought on ebay because I needed linkages and an air box. 831061 has a high speed needle valve, 631061 doesn't. <br /><br />Can I measure the jet size?

Oh oh !!<br /><br />You are correct, the info in my post above is wrong.<br /><br />I was in a hurry and didn't notice the difference in the numbers.<br />Sorry to have misled.<br /><br />Would be nice if 12footer would see this thread, I bet he would know.<br /><br /><br />When all else fails, contact www.themarinedoctor.com for info on Force motors.
