I just purchased a 1980 Helms 27 with a bad 15 HP OMC Zepher. I am told the engine ran last year but now water is blowing out of the lower cylinder. I have removed the engine and I am in the process of hanging an outboard on her. I believe the rest of the engine and parts are still in good shape.
I am willing to sell the the removed engine with wiring harness
for $200 plus shipping if needed. If interested you can contact me at email@example.com
