87 mkII with M25XP
I just spent a few days in Catalina. Motor sailing the entire time.
the way there everything was normal, cruising at 2200RPM, no issues.
after anchoring and then leaving to fish, I couldn’t get the motor over 2000RPM at all. Last time that ever happened I got kelp wrapped on the prop and was able to clear it in reverse. This time it didn’t change and I even dove under to check and everything looked clean around the shaft and prop. I have a two blade folding prop. At some point later it seemed normal again and we motored on.
Then the next day, it was again limited to 2000RPM under power.
In neutral, it idles at 800 and I can WOT up to 2900 RPM.
we motored home 6 hours at 2000RPM, no overheating issues, and we were going the normal 5.9-6.1knts I usually get, but I feel like the fuel efficiency was also poor. I used about 10 gallons for about 12 hours total of motoring.
I normally can run the RpM’s well above 2000RPM even under power.
I just tested it at the dock tied up and got the same thing, maybe even less like 1900 RPM max.
Looking for suggestions and any advice.
I read some comments from others about running injector cleaner through it.
Any other thoughts?
Thank you.
