I inherited an engine with my boat that was messy. I was able to get it running and seemed to work "ok" but at times it seemed sluggish. I pulled my little 2-cyl engine off the boat while I worked on another project
. At first, I decided to just clean off some bad spots and a repaint would be all that was needed. Once I started removing parts
, I really got to see the condition this engine was in. Some of the cooling
passages were clogged, the exhaust
valves were almost clogged with carbon build up, exhaust
had built up with carbon and rust, and one of the pistons had a crack.
Some of this, I would not have known if I just left it alone. I did a rebuild over a few months this past winter and now runs wonderfully.
Sad thing is, the hour meter read 716hrs, but I found out the positive side was disconnected, so I can only guess at the actual hours. My guess is 730. This engine was almost DEAD because the PO didn't take care of this engine. Way too low of hours to be this far gone, and luckily I saved it from a horrible death. Now, it sits in my garage waiting to be put back into service
So, don't go off hours alone. Best to get someone who can thoroughly inspect the engine. If it checks out, you'll be good for many hundreds of hours. Don't skimp on maintenance intervals for changing impellers, oil
, belts, gaskets, filters, etc.... if you see a leak anywhere, find out where it's coming from then decide on course of action to fix it.
It's likely that engine has plenty of life in it as is. Couldn't hurt to get it checked out by a professional.
