To many things were bothering me about trying to get the I6 engine ready, so I have come across an alternative plan and found another engine, this was a cheap ‘unknown’ gamble from eBay. Its a 1979 150hp 2.0 v6 Mercury.
Only picked it up yesterday, but gave it a service today, and a carb rebuild. Seems to run quite happily now. Compression is a little down on one cyl, but that may be a stuck ring, bores however all look just fine.
Crazy things these engines however. Had it running on idle for about 30 mins and it used 3 litres of fuel… Madness.
At the very first opportunity now I’m going to be bolting this engine on!
