Will This Spark PLUG WORK:"""

[longstand]

when i purchase the boat i decided to change the spark plug

i notice the manual said it should Use AC MR44T

But it has MR45T. it work just find..

would it make any different at all.. because i just purchase the spark plug and found out i should be using the MR44T..

What is the different and will it hurt my engine or Fuel consumption??

Sure it does not call for MR43T? I don't recall seeing a 45T marine plug.
Could be a different heat range...not sure.
