mercruiser 165 won't crank

[michael s.]

my mercruiser won't crank it ran fine last year when i put it away for winter .i am wanting to know if i can use starting fluid to get it to bust off or should i stay away from it? also can i use parts from a chevy 265 inline six like i have been told? if so then parts like plugs, wires and dist. cap could be bought at auto parts store correct? along with the coil if necessary. any ideas on where to start, to find out what is causing it not to crank?fuel?spark?
i assume it would be like any other engine check for fire first correct?

You might start with looking at the "Adults Only" thread at the top of this forum page where Don s has posted great diagnostics for just this such thing. Can the starting fluid!!!

That's what I'd do. See if you're getting spark, then if not, check to make sure there's no corrosion in the wiring. I'm sometimes guilty of stampeding toward the most complicated solution when it turned out to be something really simple.

Stay away from starting fluid. This engine will usually fire right off even if 2 or 3 cylinders are dead.

I'm not sure about parts from a Chevy 265, but parts from a Chevy 250 sure thing except for the various parts that need to be USCG approved. I use regular plug wires and plugs, but distributor, cap, rotor...all mercruiser marine parts.

Also, the check the carb when you do get it running. If it is the 2bbl rochester...super easy to rebuild.
