Re: OMC or Mercruiser
I do not know what type of OMC was on it. I thought switching to a Mercruiser may be cheaper.
Cheaper is a relative thing...
If you're looking at a boat that has the drive missing AND it's a Cobra engine then yes you can switch it.
To make it worth while there needs to be some preconditions:
1. It probably needs to be free. (or almost free)
2.There needs to be little or nothing wrong with the boat.
3. You need to be able to find donor boat that has a good condition "correct" Mercruiser engine, gimbal and drive for next to nothing.
It's probably easier to just keep looking for a boat with the "right" engine and drive. (that means early to mid 90's Merc or 95+ Volvo.
Choose a boat with the most common and (still) well supported engines.
That means 3.0L--4cyl, 4.3L--V-6 or 5.0/5.7L--V-8 etc.
Other engines may have limited support 230/250/292 GM 6cyl.
By limited I mean the exhaust manifolds may be prohibitively expensive or no longer available from Mercruiser or Volvo and the after market has everyone by the "short-hairs"
This is just a few examples of what you need to think about. There's more.....but you probably get the idea.....
