I have a 78 Tahiti tiger bubble deck outboard with a merc 175. Oil injection decided to stop working and i seized the motor up pretty good. The cost for me to rebuild the motor or buy a new one is outrageous. So my question is, and I hope someone has the answer. Is the 18ft tiger bubble jet the same hull as the outboard? Could I convert my outboard to a jet? I have a pump and motor in my garage out of another boat that my dad graciously provided for me, but before I cut and grind, any info on this would be helpful.
