Either way ... we'll take these kind of results any day.
One of my buddies called this morning & asked if I'd be home & could look at his 150 Evinrude he'd already broken down to freshen up.
It seems his new brother in-law's boss who owns a stealership told my friend that he was really pressing his luck running an old motor with that many hours on it without freshing it up.
Of course with it being to hot to fish this am I told him sure, bring it on & I'll get the micrometers out & a manual for reference.
By 10 am we were elbow deep into the parts, it took less than 30 minutes to measure & document everything.
We took the heads to a local machinist for milling & pistons/rods to check for sizing & weight balancing. I got busy trying to convince my buddy to leave everything else as found. All of the bearings measured surprisingly close to new. The rings had no measurable wear, the piston shirts & ring glands were in perfect condition.
The cross hatch on all of the cylinder walls still looked equally healthy & not a trace of carbon deposits ANYWHERE to be seen !
This motor has 708 hours on the clock & this guy ain't afraid to run one wide open either. He has always used Lucas semi synthetic oil thru the VRO (at my recommendation) along with name brand pump gas. He & I both run a mix of Lucas oil treatment in our lower units too.
This motor is 14 years old & on it's 3rd. set of spark plugs that still look clean.
So as it stands we will replace the original rings, gaskets, seals, hoses, thermostats, plugs wires & leave the bearings alone.
He should be back together & running this weekend if the heads come back tomorrow as promised.
Total cost for this do it yourselfer will be less than $275 including the machine work.
