ready for power

[zeke]

Thanks for all the help.I have a 95 johnson 150 oceanrunner with a fresh rebuild on an old 18 foot cobia,it only has a 20 inch shaft.I was considering putting it on my seacraft but everyone tells me that I,ll drown the motor espscially backing off in a following sea.Is this information correct?Its a 26 inch bracket so I figured i would get a couple of those inches back.That being said i,m trying to save my money for a motor.So far I have 5500.00.I,m thinking maybe trade my johnson and some money Whats the real story on the 20 inch shaft.
