I am new to boating and I think I have a problem I recently purchased a 1993 Lawson All American 190 (a 19? bowrider) with 4.3L V6 GM based Yamaha I/O engine. I believe this means a GM inboard and Yamaha outboard.
The previous owner told me that he had forgotten take out the freeze plugs 2 winters ago, so the block cracked and he had a local marina put in a ?First Mate? rebuild engine in it (From the warranty, item# GM262LH, S/N: 236071). This seems to be true as I have the paperwork/warranty from the marina dated 5/4/07 when the engine was replaced.
I took the boat out on a test drive, it worked just fine, so I bought it. I have had the boat out 3 times with my family and have come to the conclusion that it is leaking about 1 quart of oil in the bilge per outing.
The ski storage and bilge area were a little oily but clean when I looked at the boat before purchasing, but when asked, the answer was that that was all there from the engine replacement.
Here are the other things I notice:
-the boat runs well.
-the oil on the dipstick looks good and clean.
-there is no external oil discharge, only in the bilge area.
-oil pressure seems OK at about 70psi when running.
-water temp is OK.
SO MY QUESTIONS ARE:
#1. Any thoughts on what this is? I assume ?IF? this was leaking when sold, then the pervious owner probably knew, and it is something ?bad?. I know this is a crazy question, but any general theories given that the engine was serviced a year ago and is there any typical problems with this type/boat/brand of engine?
#2. What course of action do you recommend? I am ?handy? but have no delusions about pulling the engine. I have been considering taking the rear seat out and other panels around the engine compartment then taking it out on the lake to see if I can see where the leak is coming from (oil filter, oil pan, seals, crack block) but it looks very tight. But in the end will almost certainly have to get someone else to do the work.
#3. The Marina that replaced the engine is about 90 miles away from where I store the boat, so I?m also trying to decide if there is any benefit in taking it back to the marina that did the work, or should I just take it to a local marina that is on the lake where I keep the boat.
Again, I am new to boating and am trying to figure out my next step. Yes, I have learned a lot about boats recently and would probably purchase one differently now (and defiantly have it checked out by a mechanic).
Thanks.

then took it out to see if I could figure out where the leak was coming from. I couldn't find it. I took it to the marina and checked it in to the service department. They should get to it later this week. I went back and forth, but decided to leave off all the stuff I had taken off . . . figured they'd just have to take it off again.
