Nah, never happened. More "Life" got in the way of this happening. Maybe next week.We'll hold you to it.
Nope.Did you ever dive the boat and clean the prop and hull?
I your problems sound like fouling to me. I know that I can easily loose 1/2 a knot with just a few barnacles on the prop.Nope.
My issue is with the engine revs under load vs in neutral. I cannot raise over 2000 when under load vs. 3500 in neutral. The black gray slush in the exhaust is slowly diminishing, which is a positive. Still working on how I can getter better rpm under load. I dont need 3500 naturally, but I used to get better than 2000. (at least 2900)I your problems sound like fouling to me.

Didn’t you say on haulout you had a surprising amount of barnacle growth? Seems like that might be correlated with the problems. You might be a little over propped to begin with if you can’t reach your full RPM’s in gear, and the extra fouling exacerbating that.My issue is with the engine revs under load vs in neutral.

Excellent detective work! Please do report back in the spring.For some reason, most likely me trying to make things tidy in the engine bay, I had run the hose under the compression lever. Thinking about this, the lever would then sit maybe slightly open which would reduce compression, which it sounds like from some of the responses, the reason for low rpms.
My experience exactly. A few giant barnacles growing on your prop will throw everything out of whack. The diesel will be overloaded, won’t get up to normal operating revs, and will smoke.One spring, 4-months after I had a diver clean my hull and prop and replace the zincs, I headed out to do some crabbing. It had not been used during that time, but this was not an unusual situation and had never been a problem before. As soon as I left the dock, I realized that something was wrong because I could not rev to more than 1500-rpm and had a lot of vibration. Surprizingly, I was still able to make 5.4kts which was much faster than normal for 1400-rpms. The diver I had been using was unable to get out for several weeks. Fortunatly, I have a couple of freinds who are dive instructors who had just gotten new dry suits and were looking for an excuse to NOT get wet. This is what they found.![]()

Then the diver cleaned the prop, he had just knocked off the bodies of the barnicles but did not scrape off the white bases. The new growth then had a foothold and came back worse than ever.
Since then, I dive my own boat. It saves me $200 twice a year and when I dive, I might have a handful of barnacles.
Well @twodzusfittings , anything new worth reporting on the problem with your low RPM ?As I have winterized the engine, I won't know until the spring, if this is actually the case. So if you can wait till the spring, I'll let you all know. If not, OH WELL!
Can you post a picture ?can you say "Hernia Operation"?
