2-stroke o'board problem

Cannot seperate lower gear unit from mid-section. Bought and read the service manual before starting project. Stumped. Any ideas?

Background: Nissan 9.9C 2-stroke. S/N 355A-1-66928. Year unknown {help?} but suspect 1993-1995.

Disconnected xmission linkage twixt lower and middle section. Removed four nuts & lockwashers that APPEAR to be only items holding both units together. Struggle, grunt and tried small mallet. Units won't come apart. Suspect old, dried-up "grease" now keeping units bound with friction, but don't know that for sure. Am I missing something? What?

Tried using small flat-tip and mallet along joining line to pry parts apart. Tried liberally coating that area with penetrating oil.

(days later) Hung the unit upside-down and liberally coated bolts with penetrating oil. (So gravity would assist penetration.)

My motor looks like a tuna hung from the boom. Next step: hacksaw.

ANY ideas out there?

Re: 2-stroke o'board problem

took me a week to free the drive on a similar engine,drive rod corroded into splined output of big end bearing,repeated heating,hitting leg with 5lb hammer freed it.

blowtorch and sae 50 oil did the trick,plus the big hammer..............

Re: 2-stroke o'board problem

Thanks, atoll.

Have Bernzomatic tourch-will fry her butt.

More info: Motor functioned pretty well on the dinghy around the harbour before I pulled her aboard. Reason(s) she's up are 1) almost no water out the tell-tale and 2) running raggedy. Bought a water pump rebuild kit and carb rebuild kit. And yes, I know about checking for salt build-up in the water cooling system. Just thought that after seven years I should really check the impellor.

Re: 2-stroke o'board problem

that's a common problem when the lower end goes too long without being removed. Patience plus persistence!
