Anybody know what carbs and intake this is?!

I just picked up a 93 sn with a 650 in it that I'm getting ready to part out but I'm curious as to the size of these carbs and the type of R&D intake this is? They look like dual 44's but I'm not sure? Any input would be great!

R&d 61x dual carb dual pulse cast manifold. Carbs can be determined by measuring the bore. Look like 44's to me which is what those manis where mainly sold for. Great setup there should fetch $250-$350 from what I've overlooked on eBay

How big of a improvement would I see over my stock single sbn44 on my 701 61x/61x with a high comp head (190psi) and b pipe?

That is a set of mismatched carbs! Be very careful. One is oem 44 and one is an a/m 44 or 46. Likely to have different internal fuel metering, etc.

Just use the 44 on your boat to match the other oem carb, I'm currently testing duals on my 61x, I think I may be beatn a dead horse with 61x cases but going to change out the thru pipe to 2&3/8 from the stock tiny guy, more air in needs more out, so far I've been impressed but not sold, my single(46fullspec on a wetjet intake) hit harder but didn't have the top and smooth throttle reponse that the duals have, I've tried different props, line restricters, stubby cone and reverse jetting seemd to really help give it the snap of the single, gettn close but I think 62t cases are on the horizon
