No it is not.------On the starboard side of the motor there is a wee oil recirculation line.-----Comes from the bottom of the motor and goes to top bearing.---Find it and inspect it.-----Serial # of your motor ?
You have to shim new gears.----Using the factory shimming unit ( I have that item ) here.------Called gear pro's some time ago and answer on shimming ( using factory tool ) was not very clear at the time.
No need to mix in a separate tank.-------Add oil then the fuel coming in will mix it all up.-----Post #1 is missing some information.----Was tank completely empty ?------How long have you owned the boat ?-----First time that you added the oil before adding the fuel ?
??----There must be a bolt on top of the bracket that the motor spins / tilts on !-----It is item 25 and has a friction block and tension spring as well.----Was motor used in salt water ?
???---Lot of speculation here and everywhere.---BRP / Johnson / Evinrude have been supplying many consumable parts for motor that were built 50 years ago have they not ?
???----Your bolts are NOT -----7/16"-----Well the wrench you use might be 7/16".-----The bolts are 5/16" mate !!!!----And the threads in the block are aluminum.
Drill a wee hole from the side near the top of the bolt.-----That gets penetrating oil in there.------Some of those bolt cavities fill with aluminum oxide and jam the bolt solid.-----Then drill through from the side to cut the bolt !!
The solenoids rarely fail on these.----Only use 12 volts when motor is in neutral for the one solenoid.----And 12 volts to both for reverse.----For most applications those solenoids are only used momentarily.-----No power to those solenoids when in forward gear !
What was the shifting issue ?-----Checked the control box and cables ?----Have you checked the gears ?----Have you checked the shift rod height ?-----Checked the cover where shift rod goes into the lower unit ?-----
Are you looking at buying this boat ??-------Remove the screws on that broken cylinder and I believe you will find one oil line going to that cylinder.
??-I say it is hydraulic.----Look inside the boat for a motor / pump / reservoir and black plastic oil lines going through the transom.----Any other pictures of this project boat ?
