Re: Will a 155 HP commercial V6 lower work with a V4 powerhead?
Before you jump into this purchase, you need to do some homework. Most commercial engine lower units have significantly different gear ratios than the normal consumer lower units.They are made to push heavy loads, so they may have odd gear ratios and their size can vary. If you do get it to fit, you may be unhappy with how it performs. You'll likely get into really odd prop pitches in order to make it run somewhat normally.
