Hi All,

Just had my bottom job done this week.   Here is my smile - top photo this weeks haulout bottom from 2017 haulout.  Bilge is dry (in summer.)

Lots of excellent information here obviously.  I figured some pics may be helpful to showcase one example of a C34 fin keel smile.

I had a similar loss of RPM issue on my '88.  I noticed that it was dumping unburnt fuel out of the exhaust which led me to believe that back pressure might be the issue and it was.  The exhaust elbow had narrowed.   Replaced the elbow and problem solved.  I didn't see this ticked off as a check in thread so thought I'd bring it up.

Similar to Scanstrut, I've used Ram Mounts successfully.  I have one ball mount by instrument panel (w wiring) and one at pedestal (w wiring routed up pedestal tube and out of bottom instruments) and a holder for a Garman charplotter.  So typically, I just leave the device connected inside at the instrument table unless I need above deck navigation (rarely) in which case I bring above and connect to the ball/wiring at the pedestal.   I also have a ram mount for ipad & iphone near instrument table (that wifis into my VHF/autopilot.)[model]=GPSMAP+741#wizard

Do you own an iPad?  If so, you can consider iNavx application on the iPad a "back up."   Just keep it in the boat unless you get a nice waterproof cover.  You could then pick up something used for primary use/marine grade purposes.  

Interestingly, on my C34 I have a Garmin primary of previous design and on my friend's boat he has a new Raymarine.   When sailing on my or his boat, we always use the iPad because it is so easy/intuitive to use...  

Agree that integration is another topic/key issue per the previous post.

I hear you on that.  Engine starts/runs perfect with no smoke so think I'm ok on that front.

My theory is the raw water nipple extended a bit too far into the exhaust pipe which created a place for junk - carbon, salt etc to form.

Hello everyone,

I installed the new exhaust riser (from Catalina Direct) and the problem is solved/all is good.

The boat revs even higher now in gear - 3000 - with my 15x10 flexofold - whereas before it went only to 2850/2900.  Interestingly, maybe this riser is a bit less restrictive.  I did note that the raw water nipple doesn't extend as far into the exhaust pipe on this version.

Thanks for all your comments/help.

Bingo.   Just pulled hump hose and exhaust riser is blocked right in front of the place where raw water injects. 

Time to pull the 6 year old riser and either clean or get a new one.

Thanks again for everyone's help.

Breather tube runs down to oil absorbing pad under engine.  Silver dollar sized black mark to where the tube blows.  Oil engine level was perfect when I checked it when this symptom first arose.

At this point, I think I will check exhaust, then check injectors, then replace injectors or then have someone replace/rebuild injection pump...

Thanks Ron and Ken.  That is on the next steps list.  Did some more symptom checking though today. 

Boat idles to 3100 fine.  Reverse at dock 2400 max and fuel in exhaust as before.  Removed k&n airfilter - no impact to symptoms.  Screwdriver to ear on the 3 injectors and they all sound the same.  Noticed air filter was black with what appears to be oil or fuel.  Was red not too long ago.  Now thinking exhaust may be restricted causing too much back pressure as another potential cause?  Elbow is only 6 years old - muffler and exhaust hose original.  But cooling water seems to come out the back fine.  Or does fuel in an air filter also arise with any cause of unburnt fuel including injectors?  Maybe I am grasping at straws.

Haven't done any diagnostics yet - just observing symptoms.  Besides a bit of gray smoke, all seems normal at start and cruise rpm of 2200 which is making me scratch my head.  I will check injectors and cylinder firing as suggested here soon and will update.  Thanks for everyone's advice/thoughts.  Kurt

Thanks for the comments everyone.  A new datapoint - my boat use to rev to 2850 per meter on boat.  Now it can only go to 2400 and then I see the unburnt fuel pouring out via the exhaust.  At cruising rpm of 2200, maybe a bit of gray smoke but power output seems fine.  Forgot to check the idle max rpm.  Still thinking fuel issue - maybe the high pressure fuel pump?  Kurt

Hello Stu,

I guess I sail a bit too much (and motor a bit too little.) 

I started the boat yesterday and upon startup saw some black come out of the exhaust initially creating a bit of a black sheen on the surface of the water, then idled fine.  Lately though I see the smoke and black injected into the water only after the boat is well warmed up.  Am starting to think it is showing the symptoms of being slightly overpropped - I get to 2800 rpm max, flexofold 3 blade 10x15.  Next time out will try to examine the situation more closely at varying rpm levels.    Thanks for the advice/thoughts.

My '88 (1300 hours) has just recently begun giving off some smoke and I noticed looking behind the boat that fuel is coming out of the exhaust. I can see the black fuel in the water.   Boat starts fine, runs fine and is not overheating.  (I've previously sorted out the hx and am pretty sure that is not an issue.)

Should I just replace the injectors?  Check the valves for adjustment?  (Or hire a mechanic to further diagnose.)

Any insight appreciated.
