"I have a 1999 Cobalt 190 with a Volvo Penta 5.0 GISX (ser# 4110182291). I didn't winterize it and marina says I have a "frozen busted engine" and it will be $6000 to replace it. They said when they tried to lauch it, but at start-up, water was coming out of the engine and that's evidence of a "busted" engine. I can't afford $6000 right now, so I'm looking for a way I can do it for less on my own - or with the help of a buddy who's a very good mechanic. He's a Class A mechanic and said he could install a new/rebuilt replacement long block engine for $2700 (his/my cost) if I give him a hand. My questions are: 1) How do I tell what damage has been done and to what components (i.e. block, heads, exhaust manifolds, etc.)? 2) If I replace the engine, do I need to replace the exhaust manifolds and elbows also? 3) What else would need to be replaced when installing the long block (i.e. intake mainfolds, etc.)? 4) What steps are involved in installing the engine (i.e. removing fuel and power steering lines, etc and what about the stern drive...)? Is an experience mechanic and race car builder likely to be able to handle the marine engine replacement? Any special tools, hoist/lift, etc required? Sorry for all the questions. Thanks in advance for any quidance you can provide!!!"

"John, your case seems to be rather common. It still baffles me that many people do not invest in a closed cooling system when they buy a boat so that they eliminate the risk of cracking the block in areas of cold winters.

Now, to your questions.

1) An indication of an internally cracked block or head would be water in the oil. Water coming outside the engine could be as simple as a popped freeze plug, but in most cases there is further damage. One thing you can do is install a blank between manifolds and risers, then remove and plug the discharge hose from the raw water pump, then pressure test engine and manifolds at the time. If unable to keep the pressure (or if you see water coming out or flooding the crankcase) then you know you have a problem. After stripping the engine from manifolds, heads, etc, you will have to pressure test/magnaflux individual components to see what is and what is not salvageable.

2) It all depends of their condition.

3) All the parts in good condition can be transplanted to the new long block.

4) Get a copy of the Seloc repair manual, it explains the process very well. Your friend will have some reading to do, but his chances of success will increase."

"You can go to this site and download for free the operators' manual for your engine:

http://www.volvo.com/volvopenta/global/en-gb/marine_leisure_engines/engines/out_ of_production_engines/out_of_production_engines.htm

Between that manual and Clymer's (I would favour Seloc over Clymer's), you should be able to do your own servicing if you are mechanically inclined.

I believe this site also sells the factory owners' and workshop manuals:
