If you do manage to find bolts for it and bolt it back together, be sure to use" "loctite" on the bolts so they don't vibrate loose again.
Even though that
engine has a big flywheel to smooth rotation, it jumps around quite bit as I
recall. Could be the reason that red " coupler" was installed.
I seem to remember my
Volvo MD7 as not being very smooth, especially at low
rpm.
The " raw water"
cooling is another unusual feature of that
engine. On my
boat, I had to periodically remove the cylinder
head so I could ream out the
salt residue in the
cooling passages around the cylinders. About every 2 years I had to do this. I just lifted the cylinder
head, removed the cylinder head
gasket and went to
work and then just replaced everything, using the same cylinder
gasket. It never skipped a beat..
Despite all that, it proved to be a remarkably tough and dependable engine. I had it in my
boat for around 10 years, but finally traded it in for the newer 2003 series...even more remarkable, I found out later, that someone had bought my old engine.
