Elbow Leak
So I have an '89 Merc 454 with a miss....
(this is a 44 Tollycraft CPMY)
Ran compression, 125# on all but no. 4 which is at 80#. I can also see signs of rust under that cylinder and on the elbow/riser. Looks like the classic leaking Merc elbow.
Customer wants to contain costs so I shoot him a price to re-work that head and replace the exhaust on that side (inboard side fortunately!) as a minimum but caution that that is all based on what we find when the head comes off.
Here's what I found in the center two cylinders. (4 and 6) Hard to make out anything in the crappy phone pictures but you get the idea. No big scratches, but #4 looks pretty crappy and #6 clearly had water sitting in it at some point. Not a lot, but some judgeing from the marks.
I've just forwarded this on to the customer recomending we pull the engine - if you're going to do it, you might as well do it right. Of course, that's going to crank the price up significantly since it means hauling the boat, removing the salon window and running a fork lift stinger in to lift the motor out, tearing the motor down, etc.
The question: if he doesn't want to pony up for doing the motor, what do you think the odds are those cylinders will come around?
