Fred on the left is an gator, Barney on the right is a crock
what is missing in the pic is the water moccasin and other reptiles in florida that want to kill you.
If you got a 1996 or later vortec. I would look at a billet aluminum front cover and a custom oil pan. Use the marine accessories from the 1994. Buy manifolds.
If it was me, I would go V8. Same work, same cost, more power
Design life is 15 years
Service life depends on many factors
As for hours, I would expect 3000+ if maintained
Marine motors are usually killed by lack of maintenance, the hardly ever die of old age
Block doesn't care what heads. Only the intake cares
Drive doesn't care what heads, only cares about what flywheel
Main difference between the 1993-1995 motor and the 1996-2003 motor is the heads (and plastic oil pan)
If you get a motor from an s-10. You only get the short block and heads...
Unless the tub is big enough to get the whole drive submerged...... It won't work
Hint, to get the drive submerged, you need to have the boat floating.
Best bet.
Pull the drive
Hook up hose to thermostat housing
Drain when you're done
If it's carbureted, most likely the carb needs work and the accelerator pump circuit is plugged
However without trouble shooting, it's only a guess
Start with a compression test
See if you see two fuel streams when applying throttle
Was a heat deformed terminal.
3rs from end, bottom row of red connector
Couldn't get the terminal out of the connector.
So a bit of 16 gauge wire resides inside the terminal with the BCM pin
I just want the name of the engineer that thinks this is a good idea.......
going to assume 90% that there are Z-clips and flat clips. you can see the bolster flat clips in the pics and the seat back rest flat clips. (pull the screws out of the flat clips to slide the seat back up off the Z-clips.
bottom should be similar.
