USN and USMC patrol, bombing, patrol-bombing, and photo recon squadrons were credited with 131 multi-engined Japanese aircraft types during the war. USMC night fighter squadrons, operating PVs, were also credited with 5 multi-engined shoot downs, 4 G4M and 1 Lockheed Type 14-38 (yes, the Japanese started the war with about 30 of these, acquired in 193

. PVs were generally in USN patrol-bombing squadron, at first VB and then after 1 October 1944 designated VPB, or USMC night fighter squadrons (VMF(N))
For the entire war:
USN PB2Ys in VP squadrons were credited with 5 G4M and 1 H6K.
A USN VP-23 PBY was credited with 1 H6K.
USN PB4Ys in VB, VD, and VPB squadrons were credited with 11 G3M, 46 G4M, 6 H6K, 10 H8K, 14 Ki-57, 2 J1N, 2 Ki-21, 2 Ki-45, 5 Ki-46, 2 Ki-51, 14 Ki-57/L4M, 6 L2D (Japanese licensed production DC-3), 13 DC-2 (yes, as with the Lockheed 14-38s, the Japanese did have DC-2s, starting the war with about at least 14, purchased in 193

, and 1 each P1Y, Q1W, and Ki-49.
USN PVs from VB-148 were credited with 2 G4M.
Of course, this doesn’t begin to address the single engine types credited to the USN and USMC multi-engined patrol, patrol-bombing, and night fighter squadrons. On the other hand, overall, from the entire war, there were a total of 28 PB4Y, 36 PBY, 3 PBM, and 6 PV shot down by enemy aircraft (1 PBY and 1 PV night fighter from these totals were USMC, the remainder were USN). These losses include those lost to single engine types, which, of course were the source of almost all the losses.
I don’t have credit to loss by type for the entire war, but I do for the period 1 Sep 1944 to 1 Sep 1945. In this last year of the war there were 64 USN multi-engine vs multi-engine credits. Almost all of them went to the PB4Y patrol and photo recon squadrons, which garnered a total of 63. There were no USN aircraft in these actions. PB4Y credits for this period were 7 G3M, 14 G4M, 3 Ki-45, 3 Ki-46, 3 Ki-51, 2 Ki-21, 1 P1Y, 1 Q1Y, 8 DC-2, 6 L2D, 14 Ki-57/L4M, 5 H8K, and 3 H6K. The sole other multi-engined credit was split between two PB2Ys from VPB-13 for an H6K.
