I bought a boat with a 225 OX66. It has sat for 2 years. It "appears" to be a very clean motor and in great shape.
I plan to compression test first before starting the maintenence process.
I have pumped out the old fuel and cleaned tanks.
Any specific advice when performing the compression test?
My understanding of how I should do it-tell me where I am wrong
-remove all plugs and wires
-remove safety fob
-insert compression gauge -starting at the top
-crank a few times until gauge maxes out
-proceed down the block
What all would you guys recommend replacing out the gate?
