- My Westerbeke Universal M-25XP is only getting 1900 RPMs at full throttle. Catalina 34. Looking for advice. For some reason the comments are disabled, I can’t figure it out.
To remove the gear case housing, I believe also requires removing the injector pump. If so, they may have mis-installed the governing springs. There are three springs to re-install: a start spring which has one end attached to the gear case housing itself, and the speed control springs which are actually TWO springs nestled one inside of each other which transmit the throttle command to the governor.
If they forgot to install both of the speed springs (especially the heavier stronger spring), this would explain your problem. See this video to get an idea: ua-cam.com/video/Odd-41rclnE/v-deo.html
It was the governor spring. It had slipped off
Maybe the motor only turns 1900? I like my MB 168F air cooled. Lighter and no salt water to break things.
I have the same problem on the same engine. Just rebuilt the transmission, cleaned the fuel system and replaced the thermostat and sender. Now it wont go above 1900rpm. The last 1/4 of my throttle produces no extra RPM'S. Did you resolve this issue? Thanks
I'm having the same problem now, but I can hit 2000RPM. After that the last 1/4 of the throttle does nothing.
Maxwell, did you figure your issue out?
Was the purpose of moving the timing chain cover to gain access to the valve above it? Was the cam, crank or chain touched what so ever? If it was, this may be the issue. Possibly re assembled with the timing off a few degrees which now manifests itself in loss of power. Just a thought.
Seafoam is disaster! cleans the oil film between piston rings and cylinders so they move metal to metal.
WE are have the opposite problem....boat runs at FULL TILT BOOGIE...seems injectors or governor is stuck? Any suggestions...where is the governor located?
did you ever figure the problem out?
Governor spring was installed backwards.
@@catalinadude6218 where is the governor spring?

Cool channel! I have a lot of memories on a C22 and a capri 25
I have the same engine with the same problem ever fix it?
It was the governor spring
Easy fix? I Didn’t even know what that is
Is it the governor ?
