I recently purchase a boat/trailer and noticed that the tires on the trailer are at 15 PSI even though MAX tire pressure marking is listed as 60PSI. Should I bring them up to 50PSI and leave some room for expansion due to heat?
I recently purchase a 20HP Yamaha motor and would like to know its built year.
Model 20SH
Code 6A9S
Serial 014970
I was told mid 90's Any info would be appreciated.
Thanks.
