[Amel Yacht Owners] Low Revs.........

Get 12 buds. And your uncle. 
Then make sure you have the “paid professional” on back up. 

I don’t have a SM but 2800 seems in the ball park. Yes?  

See you in Bonaire!!

Hello Amelians- Would love to get advice, so please indulge me. Situation: I'm in Martinique, three weeks from heading to Bonaire for hurricane season.........then Aruba, Columbia, Panama, and through the canal......i.e. about to head away from the island chain and abundant technical support.

Through owning L'ORIENT (SM2K #422) for 8 years (and being cheap), I've become fairly technically competent with the boat and haven't paid for a technician in years.........and owe a lot to the posts I've read here for that. While not every repair has been smooth I've found the answer is always in this site. In maintaining the boat, I try to balance opposing cliches......."don't fix it if it isn't broken"........and "you can't be afraid of your boat".

So, the other day I decide to test the engine and attempt to get the revs up while motoring...........can't get above 1900 RPM. No big deal........it must be a dirty prop, like always..........so I dive on the prop and find some peach fuzz and a few smalll barnacles but not enough (in my estimation) to cause the loss of revs (this has happened to me before quite often when I lived at Miami Beach Marina for 2 years).

So after cleaning the prop I test the boat again and am able to achieve 2800 RPMs without vibration or problem (a bit of additional exhaust smell maybe but I think that was wind direction). This still leaves me uncomfortable since I feel like there should have been more fouling on the prop.

I have in my spares 4 new fuel injectors, guides, fuel line, etc........everything I need to change the injectors; however this is a project I've never done before. I'm normally decisive in this situation but don't really have a direction figured out yet. So, what now ?

1) do nothing......engine has only 2600 hours and things seem OK now. Also, it might not even be the injectors !!!

2) pay a guy to change the injectors and test the engine (hate this option)

3) change the injectors myself (my uncle, the former chief mechanic for a major US city thinks I'm a wimp to even consider paying someone else.........says he could do this in an hour while drinking 3 Buds).

My hesistancy to reflexively go to the "do nothing" option is that if the problem re-emerges in someplace less saturated with potential help I will wish I had dealt with it now.

Thoughts ?
