Compression test done ?-----Head gaskets were not the best designed item.----Is the shock absorber / slip clutch in the lower unit binding ?----Gas cap is to be CLOSED on the pressure system.-----So perhaps the float valve is leaking and flooding the motor.
Long shaft or short they run the same.----The " sail " motor exhaust was plugged above the prop.-----5" or 10" extensions redirected exhaust above the prop.----Not sure why you are having these issues.
Well------What happened is that likely the lower unit was removed in NEUTRAL.-----It then jumped into forward ( spring loaded clutch dog ) while being worked on.---Then on assembly it was in forward while control was in neutral.-----Correct on my assumption ?-----So now you need to fit the shift...
Let the oil drain for 2 days.----Then fill with TYPE-C for electric shift ( BRP PREMIUM BLEND ) and enjoy that fine electric shift motor.----No damage was done by the 80W90 gear oil.
The pulse hose may go to a fitting on the carburetor.-----That fitting may hide a little bladder ( used to be red years ago ) and that bladder might be called a fuel pumping element !
Test the hot light.-----Replace bulb if it needs a new one.-----Yes temperature gauges can be found if you search and per haps E-Bay or AMAZON will help.
Does spark jump a gap of 1/4" or more on an open air test device.-----A sparkplug laying on the block is NOT a good test.-----Is the filter screen and valve on the tank clean ?
They made changes from one year to the next.-----If there is provision for the o-ring then use it.----If no groove install it as is.----Both impeller styles will work just fine !!
The moving part of the oil pump is just a wee piston with an o-ring in a bore ( 3/8" diameter ) and is very rugged.------That part of this wonderful pump rarely fails.------These VRO pumps are not well understood , appear to be complicated and voodoo.
It does not use vacuum.-----Most of them used 2 impellers !!----One to provide cooling water to engine.----One to pump out leaky cedar strip boats.----Remember the 50's and 60's were a simpler time.
Your location ?----And what parts would you be looking for.----Most consumable parts for that 1972 motor are readily available.----Used parts are available if you know how to shop.
Any one who runs a motor with VRO in Canada ( 7 months of storage ? ) needs to accept that running the first tank in the season should be 50:1 mix.----Then if you have confirmed that VRO is indeed injecting oil you go to straight gas.-----Or pay the shop to verify operation of VRO and...
The wire may be for overheat warning.-----The cylinder thingy is the ENRICHER.----Used instead of choke flappers.----It does not need to be attached to anything.
