Sorry guys, work got in the way. Thanks for all your input.
It is a ford engine, the former owner said it was a 302. I'll try and get some pictures in the next few days. Being an outboard guy the I/O is new to me. I noticed that when we would use it and then it would set for a couple of weeks...
I have an early 70's 18' tri-hull with an inboard/outboard. We bought it used with a ford car engine in it which the former owners installed. That engine has gone bad now and I am looking for a source for a rebuilt or new marine engine. I don't know what was originally in it. We have done a lot...
