What is the ---" backside "-----Of the engine.-----Post some pictures.--------Sounds like the oil recirculation system.-----Or part of the electric primer valve hoses.
They had a ---" make room on the shelf " sale on them till they ran out.----$250 was last price.-----Down from about $2000 or so.-------Your location ?-----Good used is the option as you already know.
The non power trim ( 6 amp stator ) V-4 models had a lifting bracket on the engine.-----I welded a piece of 1/4 flat bar to an extra flywheel nut for a custom lift device.
Those splines need to be greased.------Misalignment between lower unit and powerhead ( bent / warped exhaust housing ) can cause it too.-----Crankshaft is hardened steel. and not stainless.
Sounds like throttle plates opening too early.-----And most motors rev up in neutral on a hose.-----Means nothing.-----Perform procedure know as ---" link and sync " on this motor.
Bad design is using wood as the structural element in a boat !!-----These drain holes are fairly common in older boats.---Just because water has a way of finding it's way under the floor.-------Wood in a fiberglass boat should be outlawed !
If the cast iron cylinder is not cracked I would simply run the motor.----Welding may make things much worse !!!----Did you have pistons out of the cylinders , yes or no ?-----Any pictures of pistons / rings ?
Crazy man.----Look at the 1983 model 235 HP parts diagram.-----The thermostats are in the cylinder heads.----I have 1 or 2 of these powerheads !!------Crazy easy to service !!
Drain carburetor bowl.----Use primer bulb to full it again.---Try starting motor.-----In the future run carburetor empty when done boating.----Fact, an empty carburetor does not gun up.
The wee key just keeps the bearing housing from turning.----That key will fall out if and when you get the bearing housing moving.-----Corrosion product / nature have jammed it up !!!
Very hard / impossible to disable compression release on these !!!----A leak down test would be easy to do if you know how the compression release works.----Just have to rotate the crankshaft so valves are both closed !!
Most motors rev up in neutral.---Even running on 2 of 3 cylinders.-----Not a good test of anything.----Have carburetors been properly synchronized with vacuum gauges ?
