Joe!  PM Sent.

As of now...I have a little figuring to do.  I need at a minimum, 32" from the transom mounting bolts vs. the 26" inches that the 3.0L takes up.  That means cutting...and I'm not sure I'm willing to do that with Barfly.  If it wasn't in such good shape...no problem.  No so sure...could cut it, and use the seat backrest to hold it all together.

However, as you can see, the bench would more considerably forward, to the point of being unusable.

Decisions...

I know the feeling Doran. When we were wanting to repower Phoenix the 3.7 was an option until I got the measurements from Rich. If we would have went that way heavy fabrication work would have been performed and a sun pad, rear bench and bucket seats installed.

There was room in my boat for the engine because the hood and engine bay were designed to accept in-line 6 engines. Look at the relation between the front of the mounts and the seats/side upholstery when comparing my original engine to the 3.7 liter. The 3.7 mount is about 6 inches further forward.

Yep, I was hoping that the 6" was going to be 'low' underneath that cross brace and I could make run under the bench.  I'll save this motor for something else.  Its been a fun project.

I'll need to winterize this one soon I suppose.  Should be quite easy right?  Drain heat exchanger...done, right?

Barfly is back together.  Ready for the trip to MN for storage.

Treat the gas, run and fog it out, drain the heat exchanger through the rear-most drain plug and refill with RV non-tox antifreeze. When refilling you can pour it in through the rear hose at the exhaust elbow until it comes out through the front inlet hose. Make sure the engine has good Prestone 50/50 and not just water.

FYI Rich - Your motor's in Canada getting fixed:

I found another avenue to send them a message (through facebook) and message was received - they removed the photo from their web site.
