I have a 2001 Johnson 150 OceanPro.The boat has an 1990 Evinrude 155 Commercial Engine on it now.
I want to put the OceanPro on it.Anyone know if there are any issues doing this?
From 1996 the motors used a different wiring harness system for the system check, etc., so you will either have to buy the adapter kit or update your helm.
