Re: Engine swaps - OMC to Mercruiser, and 2.5 to 3.0
I am just about to pull my teeth and hair out all at one time? Well maybe not yet? I just obtained a 99 Bayliner Capri 1850LS Bowrider, Came with the 3.0 Mercruiser inline 4 cylinder engine. My best friend from High School bought it new in 2000, ran it for three or four summers until we had a small flood that over ran the roadways to our river covering some paved roads. This doesnt just happen around here. Here in Lock Haven, Pa 17745 Home of the Piper Air Craft Corp. Until they moved in 1982 to Florida. Back to my boat. He kept the boat stored out by his familys river lot some 16 feet above the normal river level. One year we got flooded above that level. He had the drain plug out of the boat, it filled the inside of the boat and the inside of the motor also. What he did after the water receeded was spray WD-40 into the spark plug holes and crank it over. Its kinda ran but not really. NO he didn't know enough to drain the oil pan. YES I now know these little 3.0 engines can hold about 16 quarts of flood water along with about 5 quarts of motor oil. Not good. He stored it since that flood around 2005-06 with all that flood water inside the engine. I just drained it all out of there last week. Not good. My local Boat dealer told me to drain it like i did. But then to spray WD-40 into the cylinders and after a few days try cranking the motor over again as did my buddy. I have and it seems the starter does crank over and spin just not engaging the flywheel. So i removed the starter motor from the engine and got my trusty snap on flat prybar out and tried unsuscessfully to turn the flywheel in any direction. No Luck at all. Clearly the engine is fully seized up as my buddy mentioned it was years ago. Or as he stated "Its Popped" I have wrenched on cars, trucks, SUV's, Chainsaws, farm stuff, mowers, trimmers, etc, for over 20 years now. But what i seek I can not find Rock Solid Information letting me know wether or not a GM 2.5 cylinder engine will go in place of the GM mercruiser 3.0 by swapping the heads over and maybe the oil pan. I weld and fabricate so if i need make my own oil pan then so be it? Can someone please tell me will this swap work or no. Above there are some hints. Nothing solid, Just hints. PLEASE HELP ME, I've been layed off more than 6 months and i need to make a quick fix to get this things running again and maybe the four famliy members i support can have a place to call home for a few more months after its running and sold? Maybe we all get to go for a few boat rides before i sell it to pay back rent? Thanks to anyone that took time to read my issue here. I apreciate your time and so does my kids and wife. Thanks much.
