Not really, silent service had a defective torpedo well into 1943. "From December 1941 to November 1943 the Mark 14 and the destroyer-launched
Mark 15 torpedo had numerous technical problems that took almost two years to fix."
Underrated in the general public obviously, bit overrated historically. Not to say submarines aren't of supreme importance, it's just the US was really hamstrung by torpedos and tactics.
First 6 months of the Pacific War was the hardest and won by 4 carriers. Only 1 submarine(crucial, but only because the route and Hornet was messed up) did anything at Midway. The next year after saw that carrier number whittled down to 1 carrier.
It's not like Japan had any way of protecting the convoys from airpower after being outnumbered 30 to 4 in carriers.
You can win logistically or through combat, or you could be like the US and do both. Would it have been harder without submarines yes, was it not even close if Japan had infinite shipping? yes. Even with unlimited resources the IC of Japan was too small compared to the USA. Only the USSR and USA mastered mass production techniques for war.
This is the main reason US beat Japan.
