I just purchased a 20' Wellcraft Steplift with a 1990 155 HP commercial Johnson outboard on it. The first thing I did was go out and buy the SELOC manual for 1973 - 1991 60 to 235 HP Johnsons. Problem is they do not mention my engine any where in the manual. Is there a diffrent manual I should look for or does my engine follow the 150 HP specs? My model number is J155WTXESM.<br />Thanks for any help.<br />bweir<br />FR NJ
