I will be taking my boat to yet another mechanic to have the yearly maintenance done. Corpus has no qualified mechanics that will work on inboard boats. I would like to have a check list to present to the mechanic, so I can make sure I get everything done that I wanted done.

 

This is what I have came up with so far.

 

1 Replace both fuel filters

2 Replace engine oil filter and oil

3 Check v-drive oil

4 Grease all zerk fittings

5 Check tranny fluid level (changed 7/29/13)

6 Check plugs

7 Check plug wires

8 Change cap and rotor

9 Change water pump

10 Check why engine in guardian mode

11 Clean flame arrestor (carburetor air filter)

12 Check auto bilge

13 Check all pulleys (alternator pulley is 2 years old)

14 Report engine hours from the computer

 

Have I missed anything? What else should be added?

9 Change water pump ? You mean the impeller? Also check to see if there are any grooves on the housing.

 

Check steering cable? Check rudder and grease.

 

10 Check why engine in guardian mode ?? can you elaborate?

If it's overheating..

-impeller is worn

-grooves on the water pump housing

-clog in the cooling system somewhere... like the brass inlet under the boat or by the transmission cooler

-the 160 degree check valve is going bad

-water sensors are going bad

 

I would add in replacing the 160 degree check valve (it's that temp on the black scorpion). I replaced mine after strange spikes in water temp. Fixed it.

 

-Check belts

-Stabilize fuel

-winterize?

Changing cap and rotor annually really necessary? Good list...

160 degree thermostat. That's what I meant to say.

 

Cap and rotor should be inspected and replaced as necessary. I don't think it requires yearly replacement. It's probably $25 for the parts if you do it yourself.

 

Check the shaft seal and add grease.

I was gonna say: the biggest omission I noted was not at least inspecting the impeller. Some replace every year, some every other. The problem is that if you'v e already gone throught the trouble of inspecting it, it's just as easy to change it out and it's not exensive.

Yes, my boat went into guardian mode over the weekend and that's what is spawning this thread. That needs to be determined and fixed.

It was hard to start and would fire up when in fast idle but die when going back to neutral. I had to take the cover off the carb and play with the throttle to keep her running. With me at the engine and my wife at the helm we were able to limp her back to the ramp. About every two minutes a double beep could be heard. The boat never over heated and all the gauges looked good.

Just guessing, but I would have the IAC valve/muffler checked out.

 

Does it smell like gas when it has a hard time starting?

Good list Rhunt.... Replacing cap and rotor annually is best. Cheap and 10 minute job with a screw driver...

Yes I replaced the cap and rotor a couple of years ago. I'm not 100% on dropping the boat off for all the maintenance its just the code thing that has me worried.

I'm trying to get the oil out of the engine. I have what looks like a 1/2" hose with a brass plug on the end. I thought tis was to drain out the oil. I'm now having second thoughts be cause when I in screwed the plug nothing came out. I also removed the oil cap and pulled the dip stick up just enough to let in a littl air. Am I missing something? The crucial step is....

As the infamous Bigcatpt would say "My drip, drip has now become a trickle."

 

By the looks of what is coming out it might take a couple hours to drain. Off to work.

      Just read your message regarding restoring your Barefoot Falcon.  I have a 1991 Barefoot Falcon with exact same floor issues.  I also had to replaced the stringers and am in the process of replacing the floor.  My question is regarding the need to replace the foam.  Like you I have several hundred pounds of saturated foam removed and I am not certain to replace it or leave it without foam.  Do you are anyone know if the foam is necessary for any structural support, or is it just for sound and flotation?

      Actually it has me thinking of adding something between the seat and fiberglass riser. It may even allow it to rotate?  Hmmmm

      I have been told you are the expert in setting up the S238 for a great wave. We have a 2106 s238 with the surf package, our dealer told us to fill up the boat and then use the tabs, but we have figured out the more tab we put in it the less push the wave has.
      How do we best set it up for the best wave with push? We surf regular, our friend surfs goofy and her side seems to always be great, but the regular side not so much.
      Would love to have your set up and any tips you could give. Thanks so much
