I worked on a lot of those 9.5 models in those days.-----Nothing wrong with the motor / concept in the day.---The expectation of folks is just different today.
There is no telltale fitting on this motor !!----Water must be 8" above impeller in the test bucket.------Or did the copper tube come out stuck in the pump ?----If so on re-assembly the copper tube must first be installed in the exhaust housing.----Then the lower unit is installed.------These...
That is the crossflow model.------Post another picture of the back of the block.---Picture of the cowling.-----Compression test should be done , post your numbers here.-----Puzzled by the fact that this motor has that particular rectifier.
Motors use crankcase compression to move fuel.----Some pumps use a pressure pulse from one cylinder / crankcase.----Other designs use PRESSURE from 2 crankcases.-----A 4 cylinder 2 stroke has 4 separate crankcases.
You have to make sure item #39 is clean.----This is not a mystery to us.---And does spark jump a gap of 1/4" on both leads , yes or no ?-----Fuel filter checked ??----Water pump impeller replaced ??
It is esasy to test sensor coils ( trigger ) and charge coils.-----4 coils do not fail at once.----Not sure of the benefits in testing with a " load adapter "------What is your motor doing / not doing ?
That is NOT a Trim cylinder.----If there is a hydraulic line to this item , it is a TILT ONLY cylinder.-----If there is no oil line to it it is a shock absorber.
You will be overjoyed with the way the computer runs the new motor.-----Instant starting / quiet operation.-----So if you can solve it with $$$$ you do not have any problems.
Corrosion products-------In the presence of salt water and oxygen that white powder forms,-----Called aluminum oxide.-----So now there is more material in there ( oxygen ) that jams things up very , very tight.-----So heat can be used to expand the aluminum to loosen up the steel pin.-----Or...
