Mariner/Mercury Bogging issue
I have just purchased a 150ho mariner/mercury outboard approx. 1990.
I bought the engine knowing it had this fault with the intention of breaking it for parts.
However once I took off the scruffy scratched clamshell. The engine is fantastically clean and looks like its have very little use.
Shame to break.
I was told the engine starts and runs fine in a barrel or on muffs ,put it in the sea and under load it will not rev....
Any ideas , ive tested the compression and all are around the 122-127 mark.
If its an easy fix I may keep it and fit to my boat, if not it will sadly be dismantled for parts..
