Re: 87 bayliner refurb/restoration project... "The Big Dirty"
That Big block has to Fire up!!!! by the way how did all the water get in her?
Ya, I'm hoping it will run still... Me and my buddy have come up with a 'plan' to at least hoist the motor up a few feet (i beam across the rear sides of the boat) to change out the oil pan gasket if need be.. I got in there tonight after work and it spins freely now with a 1/2" ratchet (and 1' bar) by hand, with a slight drag, but it's even. IE; no tight spots in the rotation, and I went around about 8 full revs and pushed most of whatever was in the cylinders out the plug holes. (water/oil/diesel) I'm gona give it a few more days, to make sure whatever might still be frozen to the crank will melt off, then its round 2 this coming weekend... suck the bad out, dump in fresh oil, attempt to crank...
As for it getting in, I have an evolving theory on it... It would have started even before this I'm sure, but likely most of it would be from last year, when my marina moved the boat to the front of the yard (to put for sale) and blocked it. The poor thing had already sat for 2 seasons, so the top and hatches were not keeping the water out very well at all anymore. At some point, the center hatch in the cabin got cracked/broken, and I assume the drain plug hole in the transom became blocked early last spring.. a spring and summer of rain, and no one paying attention to it filled her up pretty good, till the day the front of the hull broke/cracked at the blocking wood. That drained the cabin for the most part :lol:, but I'll bet the engine bay was still quite full, and they likely just un-clogged the plug hole, let her drain, and that was that. (keep in mind the marina was out 3 seasons of storage, as well as some outstanding shop labor/work for this boat at the time)
At this point, my marina lifted and re-blocked it but I believe there was enough water in the engine bay it could have gotten in the dipstick tube, as well as past the spark plugs (which were not very tight btw) and when I checked it upon purchase, I did notice the engine oil was slightly milky/grey but didn't think much more of it.. also, I now think it may have been getting some water in through the intake manifold to block area, as I can see some rusting areas that look to me like water was sitting for a while.. either way, its kind of a moot point now.. it got in, it likely did some damage, but time will tell if it's salvageable. If so, I'll obviously be taking steps to prevent any more such issues in the future :laugh: and be sure to test run the next boat/motor I buy :laugh:
