Hello
First time posting here. I am new also to boating and outboards. I have a 1974 evinrude 135hp. Warm #1=100; #2#3#4=125 ...I have a problem on cylinder#1, 90% a broken ring. Most of the shops in my area do not work on engines that old and do not recommend that I do without even looking at it. certainly cost/value. Before loosing more compression I opened the cylinder head and found that the #1 piston and head are damaged. A 3mm ring peace is stuck on the head.
the cylinder walls are smooth with miner scratch; their is no apparent crosshatch on cylinder walls #1 #2.; their is 1mm chipping on exhaust and air port in #1;
my questions are:
Is honing a most if i should consider changing the damaged piston.
Should I hone all cylinders or can I hone only one.
Thanks for any available help.
