Re: 1966 Sunchief Restore II- In the Beginning
Speaking from doing the same thing:
First - I got it done and everything works great. You'll need a new dash electrical harness - they changed - see if you can nab it from your engine - along with cables etc. The linkages are all changed from 1960's to 1980's.
Check the lower shift cable before you mount the gimbal housing - along with bellows etc. I think the trickiest part was getting the linkage settings beween the three cables adjusted. It was worth it for me to find a local marine mechanic do this.
The more pieces you can get from a donor the better- exhaust connectors and aluminum pieces come to mind - as even the motor and drive I had did not meet up exactly
I had the carb professionally cleaned (100 bucks) and it did wonders for performance - they dip it in a solvent that clear everyhting and put all those tiny pieces together. I would take the starter and alternator off and take them to a parts store and have them tested (usually free) before your drop the engine in. I didn't and they both needed work.
NAPA has all marine components by the way - fast and cheap!
Again - I did the exact same thing over the last 8 weeks so ask if you have ann questions.
