1972 Johnson Hydroelectric Shift - 65hp

[rexoroz]

I'm looking for some help. My motor will run but when I shift into forward or reverse it bogs and dies. Like the throttle is not opening for more gas flow.
Any suggestions. Cables seem to be working and mechanical movement in Engine.

Step #1 is to post actual compression test numbers.----A 50 year old motor with 6 owners ( ? ) could have a number of issues.
